Sequential Harmful Shift Detection Without Labels

Salim I. Amoukou, Tom Bewley, Saumitra Mishra +3

We introduce a novel approach for detecting distribution shifts that negatively impact the performance of machine learning models in continuous production environments, which requi…

Interpreting Language Reward Models via Contrastive Explanations

Junqi Jiang, Tom Bewley, Saumitra Mishra +2

Reward models (RMs) are a crucial component in the alignment of large language models' (LLMs) outputs with human values. RMs approximate human preferences over possible LLM respons…

Temporal Fairness in Decision Making Problems

Manuel R. Torres, Parisa Zehtabi, Michael Cashmore +2

In this work we consider a new interpretation of fairness in decision making problems. Building upon existing fairness formulations, we focus on how to reason over fairness from a…

Counterfactual Metarules for Local and Global Recourse

Tom Bewley, Salim I. Amoukou, Saumitra Mishra +2

We introduce T-CREx, a novel model-agnostic method for local and global counterfactual explanation (CE), which summarises recourse options for both individuals and groups in the fo…

Deep Reinforcement Learning and Mean-Variance Strategies for Responsible Portfolio Optimization

Fernando Acero, Parisa Zehtabi, Nicolas Marchesotti +3

Portfolio optimization involves determining the optimal allocation of portfolio assets in order to maximize a given investment objective. Traditionally, some form of mean-variance…
