EEG Pattern Recognition with Convolutional Neural Networks
Project Overview
EEG Pattern Recognition is a comprehensive machine learning project that combines signal processing with deep learning to analyze and classify patterns in electroencephalogram (EEG) data. This project demonstrates the application of convolutional neural networks to biomedical signal analysis, bridging the gap between neuroscience and artificial intelligence.
The project follows a systematic three-stage pipeline: data preprocessing, exploratory data analysis, and model development. It processes raw EEG signals through cleaning, normalization, and feature extraction, then applies advanced visualization techniques to understand signal patterns before training CNN models for pattern recognition and classification.
