Learning from Time Series under Temporal Label Noise

no code implementations6 Feb 2024 Sujay Nagaraj, Walter Gerych, Sana Tonekaboni, Anna Goldenberg, Berk Ustun, Thomas Hartvigsen

We first demonstrate the importance of modelling the temporal nature of the label noise function and how existing methods will consistently underperform.

Stop&Hop: Early Classification of Irregular Time Series

1 code implementation21 Aug 2022 Thomas Hartvigsen, Walter Gerych, Jidapa Thadajarassiri, Xiangnan Kong, Elke Rundensteiner

We bridge this gap and study early classification of irregular time series, a new setting for early classifiers that opens doors to more real-world problems.

Recurrent Bayesian Classifier Chains for Exact Multi-Label Classification

1 code implementation NeurIPS 2021 Walter Gerych, Tom Hartvigsen, Luke Buquicchio, Emmanuel Agu, Elke Rundensteiner

In this work we propose Recurrent Bayesian Classifier Chains (RBCCs), which learn a Bayesian network of class dependencies and leverage this network in order to condition the prediction of child nodes only on their parents.

Outlier Preserving Distribution Mapping Autoencoders

no code implementations1 Jan 2021 Walter Gerych, Elke Rundensteiner, Emmanuel Agu

OP-DMA succeeds in mapping outliers to low probability regions in the latent space by leveraging a novel Prior-Weighted Loss (PWL) that utilizes the insight that outliers are likely to have a higher reconstruction error than inliers.

Outlier Detection

Versatile Anomaly Detection with Outlier Preserving Distribution Mapping Autoencoders

no code implementations25 Sep 2019 Walter Gerych, Elke Rundensteiner, Emmanuel Agu

State-of-the-art deep learning methods for outlier detection make the assumption that anomalies will appear far away from inlier data in the latent space produced by distribution mapping deep networks.
