Blood Donor Classification Project

Project Overview

This supervised machine learning project applies machine learning algorithms to a dataset of blood donors as well as their blood feature data. With this blood feature data, the project attempts to classify patients into one of a few different classes, each class representing a different stage of hepatitis.

Python and Package Versions

For my project, I used the following Python and package versions:

You can reproduce this environment using the Project YAML file provided here: Project YAML

Folder Organization and Dataset Citation

For the Jupyter Notebooks, navigate to the src folder. The baseline evaluation metric calculation and correlation plot is done in the projectbaseline.ipynb notebook, while the project.ipynb is the most up-to-date notebook for the rest of the data. oldproject.ipynb is a defunct notebook, although feel free to explore it for any insights.

The raw dataset is found in the data folder, titled hcvdat0.csv. Preprocessed data is in the preprocessed_data

Saved figures are in the figures folder.

The final report is in the report folder.

All results are stored in the results folder in .pkl files. Note that these files are only done AFTER hyperparameter tuning. The results of the ML models are not included before hyperparameter tuning as it simply serves as a benchmark of the progression of my project, not as results that should be stored.

Dataset Information

What do the instances in this dataset represent?
Instances are patients

Additional Information
The target attribute for classification is Category (blood donors vs. Hepatitis C, including its progress: 'just' Hepatitis C, Fibrosis, Cirrhosis).

Has Missing Values?
Yes

Variables

Category: Patient classification (e.g., Blood Donor, Hepatitis, Fibrosis, Cirrhosis)
Age: Patient's age in years
Sex: Patient's gender (m for male, f for female)
ALB: Albumin, a protein made by the liver
ALP: Alkaline Phosphatase, an enzyme related to liver and biliary system
ALT: Alanine Aminotransferase, an enzyme indicating liver damage
AST: Aspartate Aminotransferase, another enzyme indicating liver damage
BIL: Bilirubin, a product of red blood cell breakdown
CHE: Cholinesterase, an enzyme involved in fat processing
CHOL: Cholesterol, a type of fat in the blood
CREA: Creatinine, a waste product used to assess kidney function
GGT: Gamma-Glutamyl Transferase, an enzyme indicative of liver disease
PROT: Total Protein, measuring overall protein in the blood
