# Biomedical Text Publication Classification Dataset
## Overview
This dataset contains text data for classifying biomedical publications. 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.
## Dataset Structure
The dataset is organized into the following structure:
Cancer_Documents_Classification/
train_data/
category_1/
sample_0.txt
sample_1.txt
...
category_2/
sample_0.txt
sample_1.txt
...
test_data/
category_1/
sample_0.txt
sample_1.txt
...
category_2/
sample_0.txt
sample_1.txt
...
**Note**: All text file names must be unique across all category folders.
## Features
- **Tabular Data**: Each text file contains space-separated values representing the features of a sample.
- **Categories**: There are multiple categories, each represented by a separate folder based on the type of publication.
## Usage (not pre-split; optimal parameters)
Here is an example of how to load the dataset using PrismRCL:
```bash
C:\PrismRCL\PrismRCL.exe chisquared rclticks=15 boxdown=0 channelpick=5 data=C:\path\to\Cancer_Documents_Classification_mm testsize=0.1 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=15`: Sets the number of RCL iterations during training to 15
- `boxdown=0`: Configuration parameter for training behavior
- `channelpick=5`: RCL training parameter
- `data=C:\path\to\Cancer_Documents_Classification_mm`: Path to the complete dataset for Cancer Documents Classification
- `testsize=0.1`: Specifies that 10% of the data should be used for testing
- `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
