Biases and Variability from Costly Bayesian Inference

no code implementations7 Jul 2021 Arthur Prat-Carrabin, Florent Meyniel, Misha Tsodyks, Rava Azeredo da Silveira

An unpredictability cost induces underestimation of small probabilities and a fixed bias that remains appreciable even for nearly unbiased observations.

Bias and variance of the Bayesian-mean decoder

no code implementations NeurIPS 2021 Arthur Prat-Carrabin, Michael Woodford

We present widely-applicable approximations to the bias and to the variance of the Bayesian mean, obtained under the minimal and biologically-relevant assumption that the encoding results from a series of independent, though not necessarily identically-distributed, signals.

Human Inference in Changing Environments With Temporal Structure

no code implementations27 Jan 2021 Arthur Prat-Carrabin, Robert C. Wilson, Jonathan D. Cohen, Rava Azeredo da Silveira

We show that humans adapt their inference process to fine aspects of the temporal structure in the statistics of stimuli.
