Extended Data Fig. 4: Full generative model of constant-volatility models.
From: Imprecise neural computations as a source of adaptive behaviour in volatile environments

This model is exactly the process generating changing environments. This generative model assumes that volatility τ is constant. zt represents the current correct combination. γ represents the probabilities of combination occurrence whenever the correct combination changes. η represents feedback noise. In every trial, observables are stimuli st, actions at and binary feedback rt. See Methods for details.
