### Introduction

Welcome to the PyTorch Hands-On Course! This course is designed to provide you with a practical understanding of PyTorch, a powerful and flexible deep learning framework. Throughout this course, you'll engage with ten carefully crafted exercises that will guide you from the basics of tensor operations to advanced topics such as convolutional neural networks, recurrent neural networks, and generative adversarial networks. By the end of this course, you'll have the skills and confidence to build, train, and deploy your own deep learning models using PyTorch.

### Course Exercises

1. **Introduction to PyTorch Tensors**
   - **Exercise**: Create and manipulate tensors. Perform basic tensor operations such as addition, subtraction, and element-wise multiplication.

2. **Linear Regression with PyTorch**
   - **Exercise**: Implement a simple linear regression model from scratch using PyTorch. Train the model on a small dataset and visualize the results.

3. **Logistic Regression for Binary Classification**
   - **Exercise**: Build and train a logistic regression model for a binary classification task (e.g., predicting whether a student passes or fails based on study hours).

4. **Feedforward Neural Network (FFNN)**
   - **Exercise**: Implement a multi-layer feedforward neural network for a classification task (e.g., MNIST digit classification). Use PyTorch’s built-in modules and functions.

5. **Convolutional Neural Networks (CNNs)**
   - **Exercise**: Develop a CNN for image classification using a dataset like CIFAR-10. Include layers such as convolutional, pooling, and fully connected layers.

6. **Recurrent Neural Networks (RNNs) and LSTMs**
   - **Exercise**: Create an RNN or LSTM network to perform sequence prediction (e.g., text generation or time series forecasting).

7. **Transfer Learning with Pre-trained Models**
   - **Exercise**: Use a pre-trained model (e.g., ResNet, VGG) from the PyTorch library for a custom image classification task. Fine-tune the model on a new dataset.

8. **Natural Language Processing (NLP) with PyTorch**
   - **Exercise**: Implement a text classification model using an RNN or a Transformer-based model. Train the model on a dataset like IMDB movie reviews for sentiment analysis.

9. **Generative Adversarial Networks (GANs)**
   - **Exercise**: Build and train a simple GAN to generate synthetic images. Use a dataset like MNIST to generate handwritten digits.

10. **Deploying PyTorch Models**
    - **Exercise**: Learn how to save, load, and deploy PyTorch models. Create a simple web application using Steamlit to serve a trained model for inference.
