Rational Attention and Adaptive Coding: A Puzzle and a Solution
论文指出大脑的自适应编码特性与理性注意模型预测的行为不一致,提出赫布学习作为可能的解释,适合关注行为经济学与神经科学交叉的学者。
Adaptive Coding is the property of the brain to adjust its response to statistical properties of the environment. Its effect is an improved discrimination among signals under the constraints on the dynamic range of its response. It can thus be considered the neural correspondent of Rational Attention, which models how a rational decisionmaker allocates attention among different informative signals. There is strong evidence of existence of widespread adaptive coding. Adaptive coding introduces a dependence of choice from the environment which is not observed in behavior. We discuss potential solutions and propose Hebbian learning as a potentially satisfactory answer.
