# 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: classification application |
|
chisquared: training evaluation method |
|
rclticks=18: RCL training parameter |
|
boxdown=1: RCL training parameter |
|
channelpick=5 : RCL training parameter |
|
data=C:\path\to\Haberman-Survival\train: path to training data |
|
testdata=C:\path\to\Haberman-Survival\test: path to testing data |
|
savemodel=C:\path\to\models\mymodel.classify: path to save resulting model |
|
log=C:\path\to\log_files: path to logfiles |
|
stopwhendone: ends the PrismRCL session when training is done |
|
``` |
