This repository contains the code and data for my "Machine Learning for Handling Missing Data in Wearable Electromyographic Systems" final project.

The project can be summarized as follows. First, the missing data is simulated under two different assumptions: Missing Completely at Random, and Missing Under Gait Assumptions. For each assumption, this project implements five different imputation methods: zero-imputation, mean-imputation, K-Nearest Neighbors, Gaussian Process, and Predictive Mean Matching on the raw EMG signal and study their effectiveness.

The final report is available here: https://drive.google.com/file/d/1opO8s8WlVKeHu3qXj9SBhkTk5SYA-hKq/view?usp=sharing
