MultiScale Contextual Bandits for Long Term Objectives

no code implementations22 Mar 2025 Richa Rastogi, Yuta Saito, Thorsten Joachims

To overcome this disconnect, we introduce the framework of MultiScale Policy Learning to contextually reconcile that AI systems need to act and optimize feedback at multiple interdependent timescales.

Fairness in Ranking under Disparate Uncertainty

2 code implementations4 Sep 2023 Richa Rastogi, Thorsten Joachims

While ranking can make human evaluation more effective by focusing attention on the most promising options, we argue that it can introduce unfairness if the uncertainty of the underlying relevance model differs between groups of options.

Semi-Parametric Inducing Point Networks and Neural Processes

2 code implementations24 May 2022 Richa Rastogi, Yair Schiff, Alon Hacohen, Zhaozhi Li, Ian Lee, Yuntian Deng, Mert R. Sabuncu, Volodymyr Kuleshov

We introduce semi-parametric inducing point networks (SPIN), a general-purpose architecture that can query the training set at inference time in a compute-efficient manner.
