TsSHAP: Robust model agnostic feature-based explainability for time series forecasting

no code implementations22 Mar 2023 Vikas C. Raykar, Arindam Jati, Sumanta Mukherjee, Nupur Aggarwal, Kanthi Sarpatwar, Giridhar Ganapavarapu, Roman Vaculin

The explanations are in terms of the SHAP values obtained by applying the TreeSHAP algorithm on a surrogate model that learns a mapping between the interpretable feature space and the forecast of the black-box model.

Semi-supervised counterfactual explanations

no code implementations22 Mar 2023 Shravan Kumar Sajja, Sumanta Mukherjee, Satyam Dwivedi

Counterfactual explanations for machine learning models are used to find minimal interventions to the feature values such that the model changes the prediction to a different output or a target output.

Hierarchical Proxy Modeling for Improved HPO in Time Series Forecasting

no code implementations28 Nov 2022 Arindam Jati, Vijay Ekambaram, Shaonli Pal, Brian Quanz, Wesley M. Gifford, Pavithra Harsha, Stuart Siegel, Sumanta Mukherjee, Chandra Narayanaswami

To address this test-validation mismatch, we propose a novel technique, H-Pro to drive HPO via test proxies by exploiting data hierarchies often associated with time series datasets.
