Statistics and Deep Learning-based Hybrid Model for Interpretable Anomaly Detection

no code implementations25 Feb 2022 Thabang Mathonsi, Terence L van Zyl

Hybrid methods have been shown to outperform pure statistical and pure deep learning methods at both forecasting tasks, and at quantifying the uncertainty associated with those forecasts (prediction intervals).

Anomaly Detection Prediction Intervals

A Statistics and Deep Learning Hybrid Method for Multivariate Time Series Forecasting and Mortality Modeling

1 code implementation16 Dec 2021 Thabang Mathonsi, Terence L. Van Zyl

Difficulties with applying hybrid forecast methods to multivariate data include ($i$) the high computational cost involved in hyperparameter tuning for models that are not parsimonious, ($ii$) challenges associated with auto-correlation inherent in the data, as well as ($iii$) complex dependency (cross-correlation) between the covariates that may be hard to capture.
