Explainability Via Causal Self-Talk

no code implementations17 Nov 2022 Nicholas A. Roy, Junkyung Kim, Neil Rabinowitz

We take a pragmatic view of the issue, and define a set of desiderata that capture both the ambitions of XAI and the practical constraints of deep learning.

Inferring learning rules from animal decision-making

1 code implementation NeurIPS 2020 Zoe Ashwood, Nicholas A. Roy, Ji Hyun Bak, Jonathan W. Pillow

Specifically, this allows us to: (i) compare different learning rules and objective functions that an animal may be using to update its policy; (ii) estimate distinct learning rates for different parameters of an animal’s policy; (iii) identify variations in learning across cohorts of animals; and (iv) uncover trial-to-trial changes that are not captured by normative learning rules.

Belief-Dependent Macro-Action Discovery in POMDPs using the Value of Information

no code implementations NeurIPS 2020 Genevieve Flaspohler, Nicholas A. Roy, John W. Fisher III

This work introduces macro-action discovery using value-of-information (VoI) for robust and efficient planning in partially observable Markov decision processes (POMDPs).
