Thread-safe connection pool for one host.

particular multithreaded situations where one does not want to use more

Get a connection from the pool and perform an HTTP request. This is the
lowest level call for making a request, so you'll need to specify all
the raw details.
.. note::
More commonly, it's appropriate to use a convenience method provided
by :class:`.RequestMethods`, such as :meth:`request`.
.. note::
`release_conn` will only behave as expected if
`preload_content=False` because we want to make
`preload_content=False` the default behaviour someday soon without
breaking backwards compatibility.
:param method:
HTTP request method (such as GET, POST, PUT, etc.)
:param body:
Data to send in the request body (useful for creating
POST requests, see HTTPConnectionPool.post_url for
more convenience).
:param headers:
Dictionary of custom headers to send, such as User-Agent,
If-None-Match, etc. If None, pool headers are used. If provided,
these headers completely replace any pool-specific headers.
:param retries:
Configure the number of retries to allow before raising a
:class:`~urllib3.exceptions.MaxRetryError` exception.
Pass ``None`` to retry until you receive a response. Pass a
:class:`~urllib3.util.retry.Retry` object for fine-grained control
over different types of retries.
Pass an integer number to retry connection errors that many times,
but no other types of errors. Pass zero to never retry.
If ``False``, then retries are disabled and any exception is raised
immediately. Also, instead of raising a MaxRetryError on redirects,
the redirect response will be returned.
:type retries: :class:`~urllib3.util.retry.Retry`, False, or an int.
:param redirect:
If True, automatically handle redirects (status codes 301, 302,
303, 307, 308). Each redirect counts as a retry. Disabling retries
will disable redirect, too.
:param assert_same_host:
If ``True``, will make sure that the host of the pool requests is
consistent else will raise HostChangedError. When False, you can
use the pool on an HTTP proxy and request foreign hosts.
:param timeout:
If specified, overrides the default timeout for this one
request. It may be a float (in seconds) or an instance of
:class:`urllib3.util.Timeout`.
:param pool_timeout:
If set and the pool is set to block=True, then this method will
block for ``pool_timeout`` seconds and raise EmptyPoolError if no
connection is available within the time period.
:param release_conn:
If False, then the urlopen call will not release the connection
back into the pool once a response is received (but will release if
you read the entire contents of the response such as when
`preload_content=True`). This is useful if you're not preloading
the response's content immediately. You will need to call
``r.release_conn()`` on the response ``r`` to return the connection
back into the pool. If None, it takes the value of
``response_kw.get('preload_content', True)``.
:param chunked:
If True, urllib3 will send the body using chunked transfer
encoding. Otherwise, urllib3 will send the body using the standard
content-length form. Defaults to False.
:param int body_pos:
Position to seek to in file-like body in the event of a retry or
redirect. Typically this won't need to be set because urllib3 will
auto-populate the value when needed.
:param \\**response_kw:
Additional parameters are passed to
:meth:`urllib3.response.HTTPResponse.from_httplib`

This module provides a pool manager that uses Google App Engine's
`URLFetch Service <https://cloud.google.com/appengine/docs/python/urlfetch>`_.
Example usage::
from pip._vendor.urllib3 import PoolManager
from pip._vendor.urllib3.contrib.appengine import AppEngineManager, is_appengine_sandbox
if is_appengine_sandbox():
# AppEngineManager uses AppEngine's URLFetch API behind the scenes
http = AppEngineManager()
else:
# PoolManager uses a socket-level API behind the scenes
http = PoolManager()
r = http.request('GET', 'https://google.com/')
There are `limitations <https://cloud.google.com/appengine/docs/python/\
urlfetch/#Python_Quotas_and_limits>`_ to the URLFetch service and it may not be
the best choice for your application. There are three options for using
urllib3 on Google App Engine:
1. You can use :class:`AppEngineManager` with URLFetch. URLFetch is
cost-effective in many circumstances as long as your usage is within the
limitations.
2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets.
Sockets also have `limitations and restrictions
<https://cloud.google.com/appengine/docs/python/sockets/\
#limitations-and-restrictions>`_ and have a lower free quota than URLFetch.
To use sockets, be sure to specify the following in your ``app.yaml``::
env_variables:
GAE_USE_SOCKETS_HTTPLIB : 'true'
3. If you are using `App Engine Flexible
<https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard
:class:`PoolManager` without any configuration or special environment variables.

# -- Filename generation methods -----------------------------------

# * library files (shared or static) are named by plugging the
# library name and extension into a format string, eg.
# "lib%s.%s" % (lib_name, ".a") for Unix static libraries
# * executables are named by appending an extension (possibly
# empty) to the program name: eg. progname + ".exe" for
# Windows
#
# To reduce redundant code, these methods expect to find
# several attributes in the current object (presumably defined
# as class attributes):
# * src_extensions -
# list of C/C++ source file extensions, eg. ['.c', '.cpp']
# * obj_extension -
# object file extension, eg. '.o' or '.obj'
# * static_lib_extension -
# extension for static library files, eg. '.a' or '.lib'
# * shared_lib_extension -
# extension for shared library/object files, eg. '.so', '.dll'
# * static_lib_format -
# format string for generating static library filenames,
# eg. 'lib%s.%s' or '%s.%s'
# * shared_lib_format
# format string for generating shared library filenames
# (probably same as static_lib_format, since the extension
# is one of the intended parameters to the format string)

## Kohonen Maps (Self-Organizing Maps)
This documentation explains the `CKohonenMaps` class in MQL5, which implements **Kohonen Maps**, also known as **Self-Organizing Maps (SOM)**, for clustering and visualization tasks.
**I. Kohonen Maps Theory:**
Kohonen Maps are a type of **artificial neural network** used for unsupervised learning, specifically for **clustering** and **visualization** of high-dimensional data. They work by:
1. **Initializing a grid of neurons:** Each neuron is associated with a weight vector representing its position in the high-dimensional space.
2. **Iteratively presenting data points:**
* For each data point:
* Find the **winning neuron** (closest neuron in terms of distance) based on the weight vectors.
* Update the weights of the winning neuron and its **neighborhood** towards the data point, with decreasing influence as the distance from the winning neuron increases.
3. **Convergence:** After a certain number of iterations (epochs), the weight vectors of the neurons become organized in a way that reflects the underlying structure of the data.
**II. CKohonenMaps Class:**
The `CKohonenMaps` class provides functionalities for implementing Kohonen Maps in MQL5:
**Public Functions:**
* **CKohonenMaps(uint clusters=2, double alpha=0.01, uint epochs=100, int random_state=42)** Constructor, allows setting hyperparameters:
* `clusters`: Number of clusters (default: 2).
* `alpha`: Learning rate (default: 0.01).
* `epochs`: Number of training epochs (default: 100).
* `random_state`: Random seed for reproducibility (default: 42).
* `~CKohonenMaps(void)` Destructor.
* `void fit(const matrix &x)` Trains the model on the provided data (`x`).
* `int predict(const vector &x)` Predicts the cluster label for a single data point (`x`).
* `vector predict(const matrix &x)` Predicts cluster labels for multiple data points (`x`).
**Internal Functions:**
* `Euclidean_distance(const vector &v1, const vector &v2)`: Calculates the Euclidean distance between two vectors.
* `CalcTimeElapsed(double seconds)`: Converts seconds to a human-readable format (not relevant for core functionality).
**III. Additional Notes:**
* The class internally uses the `CPlots` class (not documented here) for potential visualization purposes.
* The `c_matrix` and `w_matrix` member variables store the cluster assignments and weight matrix, respectively.
* Choosing the appropriate number of clusters is crucial for the quality of the results.
By understanding the theoretical foundation and functionalities of the `CKohonenMaps` class, MQL5 users can leverage Kohonen Maps for:
* **Clustering:** Group similar data points together based on their features.
* **Data visualization:** Project the high-dimensional data onto a lower-dimensional space (e.g., a 2D grid of neurons) for easier visualization, potentially using the `CPlots` class.
## Pattern Recognition Neural Network
This documentation explains the `CPatternNets` class in MQL5, which implements a **feed-forward neural network** for pattern recognition tasks.
**I. Neural Network Theory:**
A feed-forward neural network consists of interconnected layers of **neurons**. Each neuron receives input from the previous layer, applies an **activation function** to transform the signal, and outputs the result to the next layer.
**II. CPatternNets Class:**
The `CPatternNets` class provides functionalities for training and using a feed-forward neural network for pattern recognition in MQL5:
**Public Functions:**
* `CPatternNets(matrix &xmatrix, vector &yvector,vector &HL_NODES, activation ActivationFx, bool SoftMaxLyr=false)` Constructor:
* `xmatrix`: Input data matrix (rows: samples, columns: features).
* `yvector`: Target labels vector (corresponding labels for each sample in `xmatrix`).
* `HL_NODES`: Vector specifying the number of neurons in each hidden layer.
* `ActivationFx`: Activation function (enum specifying the type of activation function).
* `SoftMaxLyr`: Flag indicating whether to use a SoftMax layer in the output (default: False).
* `~CPatternNets(void)` Destructor.
* `int PatternNetFF(vector &in_vector)` Performs a forward pass on the network with a single input vector and returns the predicted class label.
* `vector PatternNetFF(matrix &xmatrix)` Performs a forward pass on the network for all rows in the input matrix and returns a vector of predicted class labels.
**Internal Functions:**
* `SoftMaxLayerFX(matrix<double> &mat)`: Applies the SoftMax function to a matrix (used for the output layer if `SoftMaxLyr` is True).
**III. Class Functionality:**
1. **Initialization:**
* The constructor validates data dimensions and parses user-defined hyperparameters.
* The network architecture (number of layers and neurons) is determined based on the provided configuration.
* Weights (connections between neurons) and biases (individual offsets for each neuron) are randomly initialized.
2. **Forward Pass:**
* The provided input vector is fed into the first layer.
* Each layer performs the following steps:
* Calculates the weighted sum of the previous layer's outputs.
* Adds the bias term to the weighted sum.
* Applies the chosen activation function to the result.
* This process continues through all layers until the final output layer is reached.
3. **SoftMax Layer (Optional)**
* If the `SoftMaxLyr` flag is True, the output layer uses the SoftMax function to ensure the output values sum to 1 and represent class probabilities.
4. **Prediction:**
* For single-sample prediction (`PatternNetFF(vector &in_vector)`), the class label with the **highest output value** is returned.
* For batch prediction (`PatternNetFF(matrix &xmatrix)`), a vector containing the predicted class label for each sample in the input matrix is returned.
**IV. Additional Notes:**
* The class provides several debug statements (disabled by default) to print intermediate calculations for debugging purposes.
* The code uses helper functions from the `MatrixExtend` class (not documented here) for matrix and vector operations.
* Choosing the appropriate network architecture, activation function, and learning approach (not implemented in this class) is crucial for optimal performance on specific tasks.
By understanding the theoretical foundation and functionalities of the `CPatternNets` class, MQL5 users can leverage neural networks for various pattern recognition tasks, including:
* **Classification:** Classifying data points into predefined categories based on their features.
* **Anomaly detection:** Identifying data points that deviate significantly from the expected patterns.
* **Feature learning:** Extracting hidden patterns or representations from the data.
## Regression Neural Network
This documentation explains the `CRegressorNets` class in MQL5, which implements a **Multi-Layer Perceptron (MLP)** for regression tasks.
**I. Regression vs. Classification:**
* **Regression:** Predicts continuous output values.
* **Classification:** Assigns data points to predefined categories.
**II. MLP Neural Network:**
An MLP is a type of **feed-forward neural network** used for supervised learning tasks like regression. It consists of:
* **Input layer:** Receives the input data.
* **Hidden layers:** Process and transform the information.
* **Output layer:** Produces the final prediction (continuous value in regression).
**III. CRegressorNets Class:**
The `CRegressorNets` class provides functionalities for training and using an MLP for regression in MQL5:
**Public Functions:**
* `CRegressorNets(vector &HL_NODES, activation ActivationFX=AF_RELU_)` Constructor:
* `HL_NODES`: Vector specifying the number of neurons in each hidden layer.
* `ActivationFX`: Activation function (enum specifying the type of activation function).
* `~CRegressorNets(void)` Destructor.
* `void fit(matrix &x, vector &y)` Trains the model on the provided data (`x` - features, `y` - target values).
* `double predict(vector &x)` Predicts the output value for a single input vector.
* `vector predict(matrix &x)` Predicts output values for all rows in the input matrix.
**Internal Functions (not directly accessible)**
* `CalcTimeElapsed(double seconds)`: Calculates and returns a string representing the elapsed time in a human-readable format (not relevant for core functionality).
* `RegressorNetsBackProp(matrix& x, vector &y, uint epochs, double alpha, loss LossFx=LOSS_MSE_, optimizer OPTIMIZER=OPTIMIZER_ADAM)`: Performs backpropagation for training (details not provided but likely involve calculating gradients and updating weights and biases).
* Optimizer functions (e.g., `AdamOptimizerW`, `AdamOptimizerB`) Implement specific optimization algorithms like Adam for updating weights and biases during training.
**Other Class Members:**
* `mlp_struct mlp`: Stores information about the network architecture (inputs, hidden layers, and outputs).
* `CTensors*` pointers: Represent tensors holding weights, biases, and other internal calculations (specific implementation likely relies on a custom tensor library).
* `matrix` variables: Used for calculations during training and may hold temporary data (e.g., `W_MATRIX`, `B_MATRIX`).
* `vector` variables: Store network configuration details (e.g., `W_CONFIG`, `HL_CONFIG`).
* `bool isBackProp`: Flag indicating if backpropagation is being performed (private).
* `matrix` variables: Used for storing intermediate results during backpropagation (e.g., `ACTIVATIONS`, `Partial_Derivatives`).
**IV. Additional Notes:**
* The class provides various activation function options and supports different loss functions (e.g., Mean Squared Error, Mean Absolute Error) for selecting the appropriate evaluation metric during training.
* The class implements the Adam optimizer, one of several optimization algorithms used for efficient training of neural networks.

Package resource API
--------------------
A resource is a logical file contained within a package, or a logical
subdirectory thereof. The package resource API expects resource names
to have their path parts separated with ``/``, *not* whatever the local
path separator is. Do not use os.path operations to manipulate resource
names being passed into the API.
The package resource API is designed to work with normal filesystem packages,
.egg files, and unpacked .egg files. It can also work in a limited way with
.zip files and with custom PEP 302 loaders that support the ``get_data()``
method.

""" Retry configuration.
Each retry attempt will create a new Retry object with updated values, so
they can be safely reused.
Retries can be defined as a default for a pool::
retries = Retry(connect=5, read=2, redirect=5)
http = PoolManager(retries=retries)
response = http.request('GET', 'http://example.com/')
Or per-request (which overrides the default for the pool)::
response = http.request('GET', 'http://example.com/', retries=Retry(10))
Retries can be disabled by passing ``False``::
response = http.request('GET', 'http://example.com/', retries=False)
Errors will be wrapped in :class:`~urllib3.exceptions.MaxRetryError` unless
retries are disabled, in which case the causing exception will be raised.
:param int total:
Total number of retries to allow. Takes precedence over other counts.
Set to ``None`` to remove this constraint and fall back on other
counts. It's a good idea to set this to some sensibly-high value to
account for unexpected edge cases and avoid infinite retry loops.
Set to ``0`` to fail on the first retry.
Set to ``False`` to disable and imply ``raise_on_redirect=False``.
:param int connect:
How many connection-related errors to retry on.
These are errors raised before the request is sent to the remote server,
which we assume has not triggered the server to process the request.
Set to ``0`` to fail on the first retry of this type.
:param int read:
How many times to retry on read errors.
These errors are raised after the request was sent to the server, so the
request may have side-effects.
Set to ``0`` to fail on the first retry of this type.
:param int redirect:
How many redirects to perform. Limit this to avoid infinite redirect
loops.
A redirect is a HTTP response with a status code 301, 302, 303, 307 or
308.
Set to ``0`` to fail on the first retry of this type.
Set to ``False`` to disable and imply ``raise_on_redirect=False``.
:param int status:
How many times to retry on bad status codes.
These are retries made on responses, where status code matches
``status_forcelist``.
Set to ``0`` to fail on the first retry of this type.
:param iterable method_whitelist:
Set of uppercased HTTP method verbs that we should retry on.
By default, we only retry on methods which are considered to be
idempotent (multiple requests with the same parameters end with the
same state). See :attr:`Retry.DEFAULT_METHOD_WHITELIST`.
Set to a ``False`` value to retry on any verb.
:param iterable status_forcelist:
A set of integer HTTP status codes that we should force a retry on.
A retry is initiated if the request method is in ``method_whitelist``
and the response status code is in ``status_forcelist``.
By default, this is disabled with ``None``.
:param float backoff_factor:
A backoff factor to apply between attempts after the second try
(most errors are resolved immediately by a second try without a
delay). urllib3 will sleep for::
{backoff factor} * (2 ** ({number of total retries} - 1))
seconds. If the backoff_factor is 0.1, then :func:`.sleep` will sleep
for [0.0s, 0.2s, 0.4s, ...] between retries. It will never be longer
than :attr:`Retry.BACKOFF_MAX`.
By default, backoff is disabled (set to 0).
:param bool raise_on_redirect: Whether, if the number of redirects is
exhausted, to raise a MaxRetryError, or to return a response with a
response code in the 3xx range.
:param bool raise_on_status: Similar meaning to ``raise_on_redirect``:
whether we should raise an exception, or return a response,
if status falls in ``status_forcelist`` range and retries have
been exhausted.
:param tuple history: The history of the request encountered during
each call to :meth:`~Retry.increment`. The list is in the order
the requests occurred. Each list item is of class :class:`RequestHistory`.
:param bool respect_retry_after_header:
Whether to respect Retry-After header on status codes defined as
:attr:`Retry.RETRY_AFTER_STATUS_CODES` or not.
:param iterable remove_headers_on_redirect:
Sequence of headers to remove from the request when a response
indicating a redirect is returned before firing off the redirected
request.

## Linear Support Vector Machine (SVM)
This documentation explains the `CLinearSVM` class in MQL5, which implements a **linear support vector machine (SVM)** for binary classification tasks.
**I. SVM Theory:**
SVMs are a type of **supervised learning** algorithm used for classification. They aim to find a **hyperplane** that best separates data points belonging to different classes.
**II. CLinearSVM Class:**
The `CLinearSVM` class provides functionalities for training and using a linear SVM classifier in MQL5:
**Public Functions:**
* **CLinearSVM(uint batch_size=32, double alpha=0.001, uint epochs= 1000,double lambda=0.1):** Constructor:
* `batch_size`: Size of mini-batches used during training (default: 32).
* `alpha`: Learning rate for updating weights (default: 0.001).
* `epochs`: Number of training epochs (default: 1000).
* `lambda`: Regularization parameter to control overfitting (default: 0.1).
* **~CLinearSVM(void):** Destructor.
* **void fit(matrix &x, vector &y):** Trains the model on the provided data (`x` - features, `y` - binary target labels).
* **int Predict(vector &x):** Predicts the class label (+1 or -1) for a single input vector.
* **vector Predict(matrix &x):** Predicts class labels (+1 or -1) for all rows in the input matrix.
**Internal Variables:**
* `W`: Vector storing the weight coefficients of the hyperplane.
* `B`: Bias term of the hyperplane.
* `is_fitted_already`: Flag indicating if the model is trained.
* `during_training`: Flag indicating if the training process is ongoing.
* `config`: Structure containing hyperparameters for training (batch size, learning rate, epochs, regularization).
**Private Functions:**
* `hyperplane(vector &x)`: Calculates the dot product of the input vector with the weight vector and adds the bias term, representing the hyperplane equation.
**III. Class Functionality:**
1. **Initialization:**
* The constructor sets default hyperparameter values and initializes internal flags.
2. **Training (fit function):**
* Checks if the number of samples in the data (`x`) matches the size of the target label vector (`y`).
* Initializes the weight vector and bias term to zero.
* Iterates through training epochs:
* For each epoch, loops through mini-batches of data:
* Updates the weight and bias terms using the hinge loss function and gradient descent with **stochastic** updates (updating based on a mini-batch).
* Sets the `is_fitted_already` flag to True.
* Prints training progress and performance metrics (loss and accuracy) for each epoch during training (debug mode only).
3. **Prediction:**
* Checks if the model is trained before making predictions.
* For a single input vector:
* Calculates the hyperplane output using the weight vector and bias term.
* Uses the sign of the output to predict the class label (+1 for positive, -1 for negative).
* For a matrix of input vectors:
* Iterates through each row and calls the single-sample prediction function.
**IV. Additional Notes:**
* The class implements a linear SVM, which is only effective for linearly separable data.
* The chosen hyperparameters (learning rate, epochs, etc.) can significantly impact the performance of the model. Experimentation and tuning might be needed for optimal results.
* The class uses mini-batch training for improved efficiency on large datasets.
* During training, the `during_training` flag is set to True to prevent making predictions while the model is being updated.

START state: This is the state to start with, or a legal byte sequence

ME state: This indicates that the state machine identified a byte sequence
that is specific to the charset it is designed for and that
there is no other possible encoding which can contain this byte
sequence. This will to lead to an immediate positive answer for
the detector.
ERROR state: This indicates the state machine identified an illegal byte

## Theory Overview: Linear Regression
Linear regression is a statistical method for modeling the relationship between a dependent variable (what you want to predict) and one or more independent variables (what you are using to predict). It assumes a linear relationship between the variables, meaning the change in the dependent variable is proportional to the change in the independent variable(s).
The goal of linear regression is to find a line (for single independent variable) or hyperplane (for multiple independent variables) that best fits the data points. This line/hyperplane is represented by the following equation:
`y = β₀ + β₁x₁ + β₂x₂ + ... + βₙxₙ`
where:
* `y` is the dependent variable
* `x₁`, `x₂`, ..., `xₙ` are the independent variables
* `β₀` is the intercept (the y-value where the line/hyperplane crosses the y-axis)
* `β₁`, `β₂`, ..., `βₙ` are the coefficients (slopes) of the independent variables
By fitting the line/hyperplane to the data, linear regression allows us to:
* **Make predictions:** We can use the fitted model to predict the dependent variable for new data points based on their independent variable values.
* **Understand relationships:** The coefficients represent the strength and direction of the relationships between the independent and dependent variables.
## CLinearRegression Class Documentation
The `CLinearRegression` class implements linear regression functionality. It provides methods for both training and prediction:
**Public Functions:**
* `CLinearRegression(void)` Default constructor.
* `~CLinearRegression(void)` Destructor.
* `void fit_LeastSquare(matrix &x, vector &y)` Fits the model using the least squares method.
* This method trains the model by finding the coefficients (Betas) that minimize the sum of squared errors between the predicted and actual values.
* Requires `x` (matrix of independent variables) and `y` (vector of dependent variables) as input.
* `void fit_GradDescent(matrix &x, vector &y, double alpha, uint epochs = 1000)` Fits the model using gradient descent.
* This method trains the model iteratively, updating the coefficients based on the calculated gradients (slopes of the error function).
* Requires `x` (matrix of independent variables), `y` (vector of dependent variables), `alpha` (learning rate), and optional `epochs` (number of iterations) as input.
* `double predict(vector &x)` Predicts the dependent variable for a new data point represented by the input vector `x`.
* Requires a vector containing the values for the independent variables of the new data point.
* Assumes the model is already trained (trained flag checked internally).
* `vector predict(matrix &x)` Predicts the dependent variables for multiple new data points represented by the input matrix `x`.
* Requires a matrix where each row represents a new data point with its independent variable values.
* Assumes the model is already trained (trained flag checked internally).
**Additional Notes:**
* The class uses internal member variables to store the trained coefficients (`Betas` and `Betas_v`).
* Internal helper functions (`checkIsTrained`, `TrimNumber`, `dx_wrt_bo`, `dx_wrt_b1`) are not directly accessible from the user but support the core functionalities.
* The class checks if the model is trained before allowing predictions using the `checkIsTrained` function.
## CLogisticRegression Class: Logistic Regression
The `CLogisticRegression` class provides functionalities for implementing logistic regression in MQL5. This statistical method allows you to model the probability of a binary outcome (belonging to one of two classes) based on independent variables.
**Public Functions:**
* `CLogisticRegression(uint epochs=10, double alpha=0.01, double tol=1e-8)` Constructor, allows setting hyperparameters (epochs, learning rate, tolerance) for training.
* `~CLogisticRegression(void)` Destructor.
* `void fit(matrix &x, vector &y)` Trains the model using the provided training data (`x` - independent variables, `y` - binary classification labels).
* Internally performs gradient descent optimization to find the optimal weights and bias for the model.
* `int predict(vector &x)` Predicts the class label (0 or 1) for a new data point represented by the input vector `x`.
* Assumes the model is already trained (checked internally).
* `vector predict(matrix &x)` Predicts class labels for multiple new data points represented by the input matrix `x`.
* Each row in the matrix represents a new data point.
* Assumes the model is already trained (checked internally).
* `double predict_proba(vector &x)` Predicts the probability of belonging to class 1 for a new data point represented by the input vector `x`.
* Assumes the model is already trained (checked internally).
* `vector predict_proba(matrix &x)` Predicts the probabilities of belonging to class 1 for multiple new data points represented by the input matrix `x`.
* Each row in the matrix represents a new data point.
* Assumes the model is already trained (checked internally).
**Mathematical Theory (Basic Overview):**
Logistic regression uses the sigmoid function to map the linear combination of the input features (weighted sum) to a probability between 0 and 1.
The mathematical formula for the logistic function is:
```
f(z) = 1 / (1 + exp(-z))
```
where:
* `z` is the linear combination of weights and features (z = w₁x₁ + w₂x₂ + ... + wₙxₙ + b)
* `w_i` are the weights for each feature
* `b` is the bias term
* `f(z)` is the predicted probability of belonging to class 1
By adjusting the weights and bias through training (minimizing the error between predicted and actual labels), the logistic regression model learns to distinguish between the two classes based on the input features and predict probabilities accordingly.
**Additional Notes:**
* The class utilizes gradient descent to optimize the weights and bias during training.
* Hyperparameter tuning (epochs, learning rate, tolerance) can significantly impact model performance and should be considered based on the specific data and task.
## CPolynomialRegression Class: Polynomial Regression
The `CPolynomialRegression` class provides functionalities for implementing polynomial regression in MQL5. This technique extends linear regression by fitting a higher-degree polynomial function to the data, allowing for more complex relationships between the independent and dependent variables.
**Public Functions:**
* `CPolynomialRegression(int degree=2)` Constructor, allows setting the degree of the polynomial (default is 2).
* `~CPolynomialRegression(void)` Destructor.
* `void BIC(ulong k, vector &bic, int &best_degree)` Calculates the Bayesian Information Criterion (BIC) for different polynomial degrees (`k`) and recommends the "best" degree based on the lowest BIC value (stored in `best_degree`).
* Requires `k` (vector of degree values to evaluate), `bic` (output vector to store BIC values), and `best_degree` (output variable to store the recommended degree).
* `void fit(matrix &x, vector &y)` Trains the model using the provided training data (`x` - independent variables, `y` - dependent variables).
* Internally fits the polynomial function to the data and stores the coefficients in the `Betas` and `Betas_v` member variables.
* `double predict(vector &x)` Predicts the dependent variable for a new data point represented by the input vector `x`.
* Assumes the model is already trained (trained flag not explicitly mentioned but potentially implemented internally).
* `vector predict(matrix &x)` Predicts the dependent variables for multiple new data points represented by the input matrix `x`.
* Each row in the matrix represents a new data point.
* Assumes the model is already trained (trained flag not explicitly mentioned but potentially implemented internally).
**Mathematical Theory (Basic Overview):**
Polynomial regression models the relationship between the independent and dependent variables using a polynomial function of the form:
```
y = β₀ + β₁x + β₂x² + ... + βₙxⁿ
```
where:
* `y` is the dependent variable
* `x` is the independent variable
* `β₀`, `β₁`, ..., `βₙ` are the coefficients of the polynomial (model parameters)
* `n` is the degree of the polynomial (set during object creation or through the `BIC` function)
By increasing the degree of the polynomial, the model can capture more complex non-linear relationships in the data. However, it is crucial to find a balance between model complexity and overfitting (memorizing the training data poorly generalizing to unseen data).
**Additional Notes:**
* The `BIC` function can be used to help select an appropriate polynomial degree by balancing model complexity and goodness-of-fit.
* Choosing a high polynomial degree without sufficient data can lead to overfitting, so careful consideration and potentially additional techniques like regularization might be necessary.

# because the checksum will be of the compressed
# file. This breakage will only occur if the
# server adds a Content-Encoding header, which
# depends on how the server was configured:
# - Some servers will notice that the file isn't a
# compressible file and will leave the file alone
# and with an empty Content-Encoding
# - Some servers will notice that the file is
# already compressed and will leave the file
# alone and will add a Content-Encoding: gzip
# header
# - Some servers won't notice anything at all and
# will take a file that's already been compressed
# and compress it again and set the
# Content-Encoding: gzip header
#
# By setting this not to decode automatically we
# hope to eliminate problems with the second case.
