# ECG-Synthesis-and-Classification

1D GAN for ECG Synthesis and 3 models: CNN with skip-connections, CNN with LSTM, and CNN with LSTM and Attention mechanism for ECG Classification.

## Motivation 

ECG is widely used by cardiologists and medical practitioners for monitoring the cardiac health. The main problem

with manual analysis of ECG signals, similar to many other

time-series data, lies in difficulty of detecting and categorizing

different waveforms and morphologies in the signal. For a

human, this task is both extensively time-consuming and prone

to errors. Let's try to apply machine learning for this task.

## Data

Available [here](https://www.kaggle.com/shayanfazeli/heartbeat).

## Formulation of the problem:

Each signal should be labeled as one of the classes (**"Normal"**, **"Artial Premature"**, **"Premature ventricular contraction"**,**"Fusion of ventricular and normal"**, **"Fusion of paced and normal"**).

## Solution

Code with research and solution is available here - [1D GAN for ECG Synthesis](https://www.kaggle.com/polomarco/1d-gan-for-ecg-synthesis) and  here - [ECG Classification | CNN LSTM Attention mechanism](https://www.kaggle.com/polomarco/ecg-classification-cnn-lstm-attention-mechanism).
