Custom Neural Network-Based Heart Disease Risk Prediction System: End-to-End Machine Learning Practice

The open-source project heart-disease-risk-prediction-mlp introduced in this article is an end-to-end heart disease risk prediction system. It core uses a custom multi-layer perceptron (MLP) neural network, includes modules for data preprocessing, model training and evaluation, and builds an interactive web interface via Streamlit to help medical workers and users predict and understand heart health risks.

Heart disease is one of the major global health threats, and early risk assessment is crucial for prevention and treatment. The application of machine learning in the medical field has promoted data-driven risk prediction research. This open-source project provides a complete end-to-end solution, which not only implements a custom neural network model but also includes data preprocessing, training, and an interactive visualization interface, lowering the threshold for users without technical backgrounds to use it.
