A Semi-parametric Model for Decision Making in High-Dimensional Sensory Discrimination Tasks

AAAI 2023technical

Psychometric functions typically characterize binary sensory decisions along a single stimulus dimension. However, real-life sensory tasks vary along a greater variety of dimensions (e.g. color, contrast and luminance for visual stimuli). Approaches to characterizing high-dimensional sensory spaces…

Look-Ahead Acquisition Functions for Bernoulli Level Set Estimation

AISTATS 2022poster

Level set estimation (LSE) is the problem of identifying regions where an unknown function takes values above or below a specified threshold. Active sampling strategies for efficient LSE have primarily been studied in continuous-valued functions. Motivated by applications in human psychophysics wher…
