PATE: Proximity-Aware Time series anomaly Evaluation

1 code implementation20 May 2024 Ramin Ghorbani, Marcel J. T. Reinders, David M. J. Tax

We introduce Proximity-Aware Time series anomaly Evaluation (PATE), a novel evaluation metric that incorporates the temporal relationship between prediction and anomaly intervals.

RESTAD: REconstruction and Similarity based Transformer for time series Anomaly Detection

1 code implementation13 May 2024 Ramin Ghorbani, Marcel J. T. Reinders, David M. J. Tax

This layer fits a non-parametric density in the latent representation, such that a high RBF output indicates similarity with predominantly normal training data.

Self-Supervised PPG Representation Learning Shows High Inter-Subject Variability

1 code implementation7 Dec 2022 Ramin Ghorbani, Marcel J. T. Reinders, David M. J. Tax

Unfortunately, there is high inter-subject variability in the SSL-learned representations, which makes working with this data more challenging when labeled data is scarce.
