![]() ![]() TL DR Use real-world Electrocardiogram (ECG) data to detect anomalies in a patient heartbeat. Deep Learning, PyTorch, Machine Learning, Neural Network, Autoencoder, Time Series, Python - 5 min read. hearse for sale Time Series Anomaly Detection using LSTM Autoencoders with PyTorch in Python. After training, the demo scans through 1,000 images and finds the one image that’s most anomalous, where most anomalous means highest reconstruction error. An autoencoder is a neural network that learns to predict its input. ![]() The demo program creates and trains a 784-100-50-100-784 deep neural autoencoder using the PyTorch code library.To classify a sequence as normal or an anomaly, we'll pick a threshold above which a heartbeat is considered abnormal. We'll use a couple of LSTM layers (hence the LSTM Autoencoder) to capture the temporal dependencies of the data. I'll have a look at how to feed Time Series data to an Autoencoder. ![]()
