LuminaAI/RCL-Ionosphere-Signals

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:

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

Additional Information

The data values have been prepared to ensure compatibility with PrismRCL. No normalization is required as of version 2.4.0.
