Reinforcement learning in populations of spiking neurons [PDF]

open access: yes, 2008
Population coding is widely regarded as a key mechanism for achieving reliable behavioral responses in the face of neuronal variability. But in standard reinforcement learning a flip-side becomes apparent.

Quality Diversity Optimization Method for Bilinear Matrix Inequality Problems in Control System Design

open access: yesIEEE Access, 2023
In this paper, a quality diversity optimization method (QDOM) based on an adaptive bound-searching algorithm and diversity-selecting immune algorithm is proposed for solving bilinear matrix inequality (BMI) problems in control system design. By using the

REINFORCEMENT MAGNITUDE AND THE INHIBITING EFFECT OF REINFORCEMENT [PDF]

open access: yesJournal of the Experimental Analysis of Behavior, 1979
In a two‐key concurrent variable‐interval schedule (using pigeons), if the reinforcement frequency for one response is held constant while that for the other is increased, the rate of response on the constant key decreases. The immediate reinforcement for key pecking can usually be conceptualized as the change from a condition in which the key light is
