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.

Dynamic Interpretable Change Point Detection

no code implementations8 Nov 2022 Kopal Garg, Jennifer Yu, Tina Behrouzi, Sana Tonekaboni, Anna Goldenberg

Identifying change points (CPs) in a time series is crucial to guide better decision making across various fields like finance and healthcare and facilitating timely responses to potential risks or opportunities.

Decoupling Local and Global Representations of Time Series

1 code implementation4 Feb 2022 Sana Tonekaboni, Chun-Liang Li, Sercan Arik, Anna Goldenberg, Tomas Pfister

Learning representations that capture the factors contributing to this variability enables a better understanding of the data via its underlying generative process and improves performance on downstream machine learning tasks.

What went wrong and when? Instance-wise Feature Importance for Time-series Models

no code implementations5 Mar 2020 Sana Tonekaboni, Shalmali Joshi, Kieran Campbell, David Duvenaud, Anna Goldenberg

Explanations of time series models are useful for high stakes applications like healthcare but have received little attention in machine learning literature.

Explaining Time Series by Counterfactuals

no code implementations25 Sep 2019 Sana Tonekaboni, Shalmali Joshi, David Duvenaud, Anna Goldenberg

We propose a method to automatically compute the importance of features at every observation in time series, by simulating counterfactual trajectories given previous observations.
