About
OmniAnomaly is an open-source AI tool designed for robust anomaly detection in multivariate time series. It leverages a stochastic recurrent neural network architecture, combining Gated Recurrent Unit (GRU) and Variational Autoencoder (VAE) components. The core functionality involves learning the normal patterns within complex time series data and then using reconstruction probability to identify deviations that signify anomalies. This model is particularly useful for analyzing datasets like SMAP, MSL, and SMD, which include server machine data and satellite telemetry. The tool provides a comprehensive workflow from data preprocessing to model training, anomaly scoring, and threshold determination using the POT model, making it suitable for researchers and developers working with time series anomaly detection.
