# Haberman's Survival Dataset

## Overview
This dataset contains tabular data for classifying survival status of patients who had undergone surgery for breast cancer. 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:
Haberman-Survival/
    train_data/
        class_1/
            sample_0.txt
            sample_10.txt
            ...
        class_2/
            sample_0.txt
            sample_10.txt
            ...
    test_data/
        class_1/
            sample_0.txt
            sample_10.txt
            ...
        class_2/
            sample_0.txt
            sample_10.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:
    - `class_1`: Patients who survived 5 years or longer.
    - `class_2`: Patients who did not survive 5 years.

## Usage (pre-split; optimal parameters)
Here is an example of how to load the dataset using PrismRCL:
```bash
C:\PrismRCL\PrismRCL.exe naivebayes rclticks=18 boxdown=1 channelpick=5 data=C:\path\to\Haberman-Survival\train_data testdata=C:\path\to\Haberman-Survival\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
- `naivebayes`: Specifies Naive Bayes as the training evaluation method
- `rclticks=18`: Sets the number of RCL iterations during training to 18
- `boxdown=1`: Configuration parameter for training behavior
- `channelpick=5`: RCL training parameter
- `data=C:\path\to\Haberman-Survival\train_data`: Path to the training data for Haberman Survival classification
- `testdata=C:\path\to\Haberman-Survival\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
