Fairness and Sequential Decision Making: Limits, Lessons, and Opportunities

no code implementations13 Jan 2023 Samer B. Nashed, Justin Svegliato, Su Lin Blodgett

As automated decision making and decision assistance systems become common in everyday life, research on the prevention or mitigation of potential harms that arise from decisions made by these systems has proliferated.

Causal Explanations for Sequential Decision Making Under Uncertainty

no code implementations30 May 2022 Samer B. Nashed, Saaduddin Mahmud, Claudia V. Goldman, Shlomo Zilberstein

We introduce a novel framework for causal explanations of stochastic, sequential decision-making systems built on the well-studied structural causal model paradigm for causal reasoning.

Localization under Topological Uncertainty for Lane Identification of Autonomous Vehicles

no code implementations4 Mar 2018 Samer B. Nashed, David M. Ilstrup, Joydeep Biswas

We present the Variable Structure Multiple Hidden Markov Model (VSM-HMM) as a framework for localizing in the presence of topological uncertainty, and demonstrate its effectiveness on an AV where lane membership is modeled as a topological localization process.

Human-in-the-Loop SLAM

1 code implementation23 Nov 2017 Samer B. Nashed, Joydeep Biswas

Building large-scale, globally consistent maps is a challenging problem, made more difficult in environments with limited access, sparse features, or when using data collected by novice users.
