# Ionosphere Signals Dataset |
|
## Overview |
|
This dataset contains tabular data for classifying radar returns from the ionosphere. Each sample is stored in a separate text file, with features space-separated on a single line. The dataset is structured to be compatible with Lumina AI's Random Contrast Learning (RCL) algorithm via the PrismRCL application or API. |
|
|
|
## Dataset Structure |
|
The dataset is organized into the following structure: |
|
|
|
Ionosphere-Signals/ |
|
train_data/ |
|
class_good/ |
|
sample_0.txt |
|
sample_1.txt |
|
... |
|
class_bad/ |
|
sample_0.txt |
|
sample_1.txt |
|
... |
|
test_data/ |
|
class_good/ |
|
sample_0.txt |
|
sample_1.txt |
|
... |
|
class_bad/ |
|
sample_0.txt |
|
sample_1.txt |
|
... |
|
|
|
**Note**: All text file names must be unique across all class folders. |
|
|
|
## Features |
|
- **Tabular Data**: Each text file contains space-separated values representing the features of a sample. |
|
- **Classes**: There are two classes, each represented by a separate folder based on the type of radar return. |
|
|
|
## Usage (pre-split; optimal parameters) |
|
Here is an example of how to load the dataset using PrismRCL: |
|
```bash |
|
C:\PrismRCL\PrismRCL.exe chisquared rclticks=25 boxdown=0 channelpick=5 data=C:\path\to\Ionosphere-Signals\train_data testdata=C:\path\to\Ionosphere-Signals\test_data savemodel=C:\path\to\models\mymodel.classify log=C:\path\to\log_files stopwhendone |
|
``` |
|
|
|
Explanation of Command: |
|
- `C:\PrismRCL\PrismRCL.exe`: Path to the PrismRCL executable for classification |
|
- `chisquared`: Specifies Chi-squared as the training evaluation method |
|
- `rclticks=25`: Sets the number of RCL iterations during training to 25 |
|
- `boxdown=0`: Configuration parameter for training behavior |
|
- `channelpick=5`: RCL training parameter |
|
- `data=C:\path\to\Ionosphere-Signals\train_data`: Path to the training data for Ionosphere Signals classification |
|
- `testdata=C:\path\to\Ionosphere-Signals\test_data`: Path to the testing data for evaluation |
|
- `savemodel=C:\path\to\models\mymodel.classify`: Path to save the resulting trained model |
|
- `log=C:\path\to\log_files`: Directory path for storing log files of the training process |
|
- `stopwhendone`: Instructs PrismRCL to end the session once training is complete |
