Notes on Learning
“Shopbots, agents that automatically search the Internet for goods and/or services on behalf of consumers, herald a future in which autonomous agents become an essential component of nearly every facet of electronic commerce. . . . Moreover, we predict the emergence of pricebots economically motivated agents that set prices so as to maximize the profits of firms, just as shopbots seek prices th...
متن کاملOn Generalized Bellman Equations and Temporal-Difference Learning
We consider off-policy temporal-difference (TD) learning in discounted Markov decision processes, where the goal is to evaluate a policy in a model-free way by using observations of a state process generated without executing the policy. To curb the high variance issue in off-policy TD learning, we propose a new scheme of setting the λ-parameters of TD, based on generalized Bellman equations. O...
متن کاملBellman Gradient Iteration for Inverse Reinforcement Learning
This paper develops an inverse reinforcement learning algorithm aimed at recovering a reward function from the observed actions of an agent. We introduce a strategy to flexibly handle different types of actions with two approximations of the Bellman Optimality Equation, and a Bellman Gradient Iteration method to compute the gradient of the Qvalue with respect to the reward function. These metho...
متن کاملNotes on Learning Probabilistic Automata
Alberto Apostolico y Probabilistic models of various classes of sources are developed in the context of coding and compression as well as in machine learning and classi cation. In the rst domain, the repetitive structures of substrings are regarded as redundancies and sought to be removed. In the second, repeated subpatterns are unveiled as carriers of information and structure. In both context...
