Comparison between approaches for timeseries anomaly detection
$begingroup$
After various days of research, I could take a global picture of the existing methods to perform anomaly detection on time series, namely:
Forecasting with Deep Learning. Eg. RADM or LSTM model
Forecasting without Deep Learning. Eg. Seasonal ARIMA + Kalman Filters
Denoising fixed-length windows with autoencoders (Deep Learning approach). Eg. MAD-GAN, CNN/LSTM autoencoders, variational autoencoders, etc.
Denoising without deep-learning. Eg. Applying filters such as Kalman or Hodrick Prescott, and test if the deviation of the predicted with the original timeseries is under a threshold.
Maybe there are even more methods that are not classificable into this screenshot.
My question is, which approach suits better the need of developing a timeseries anomaly system which:
- Detects anomalies in an univariate way, but allows for multivariate posterior integration.
- Is suitable for online data-streaming
- Is capable of learning data distributions holding more than one seasonality.
- [Plus] Might allow for semi-supervised improvement at any step.
