The Unofficial Kevin and Kell FAQR.L. was Kell's boss at HerdThinners, Inc. He may be a wolf; he's only seen as fangs and hands. He is 'fifty-ish'. While he is an adept manager and savage predator, he is not particularly computer-literate. He is another secret sufferer from Domestication, a malady and secret that he shares with Kell and Rudy. His predecessor at HerdThinners was named 'L.D.'. R.L. is married to Angelique, Kevin's ex.
Related QuestionsHow does RL relate to Neuroscience?
RL FAQIdeally, the ideas of reinforcement learning could constitute part of a computational theory of what the brain is doing and why. A number of links have been drawn between reinforcement learning and neuroscience, beginning with early models of classical conditioning based on temporal-difference learning (see Barto and Sutton, 1982; Sutton and Barto, 1981, 1990; Moore et al., 1986), and continuing through work on foraging and prediction learning (see Montague et al.
Related QuestionsHow does RL relate to behaviorism?
RL FAQFormally, RL is unrelated to behaviorism, or at least to the aspects of behaviorism that are widely viewed as undesireable. Behaviorism has been disparaged for focusing exclusively on behavior, refusing to consider what was going on inside the head of the subject. RL of course is all about the algorithms and processes going on inside the agent. For example, we often consider the construction of internal models of the environment within the agent, which is far outside the scope of behaviorism.

Dr. Bach was a classically trained physician who became a pioneer in understanding the relationship of emotions to the health of body and mind. Today we call this the "body/mind connection." You can also use the tongue-twister, "psychoneuroimmunology." He observed that many physical diseases could be directly related to a person's mental attitude.Related Questions

How does RL relate to Neuro-Dynamic Programming?
RL FAQTo a first approximation, Reinforcement Learning and Neuro-Dynamic Programming are synonomous. The name "reinforcement learning" came from psychology (although psychologists rarely use exactly this term) and dates back to the eary days of cybernetics. For example, Marvin Minsky used this term in his 1954 thesis, and Barto and Sutton revived it in the early 1980's.
Related QuestionsHow does RL relate to the psychology of animal behavior?
RL FAQBroadly speaking, RL works as a pretty good model of instrumental learning, though a detailed argument for this has never been publically made (the closest to this is probably Barto, Sutton and Watkins, 1990). On the other hand, the links between classical (or Pavlovian) conditioning and temporal-difference (TD) learning (one of the central elements of RL) are close and widely acknowledged (see Sutton and Barto, 1990).
Related QuestionsHow does RL relate to genetic algorithms?
RL FAQMost work with genetic algorithms simulates evolution, not learning during an individual's life, and because of this is very different from work in RL. That having been said, there are two provisos. First, there is a large body of work on classifier systems that uses or is closely related to genetic algorithms. This work is concerned with learning during a single agent's lifetime (using GAs to organize the components of the agent's mind) and is in fact RL research.
Related QuestionsMy state and/or action space is huge! Can I still apply RL?
RL FAQFunction approximation" refers to the use of a parameterized functional form to represent the value function (and/or the policy), as opposed to a simple table. A table is able to represent the value of each state separately, without confusion, interaction, or generalization with the value of any other state. In typical problems, however, there are far too many states to learn or represent their values individually; instead we have to generalize from observed to states to new, unobserved ones.
Related QuestionsIs RL just trial-and-error learning, or does it include planning?
RL FAQModern reinforcement learning concerns both trial-and-error learning without a model of the environment, and deliberative planning with a model. By "a model" here we mean a model of the dynamics of the environment. In the simplest case, this means just an estimate of the state-transition probabilities and expected immediate rewards of the environment. In general it means any predictions about the environment's future behavior conditional on the agent's behavior.
Related QuestionsWhat advantages does RL offer in Operations Research problems?
RL FAQUsing function approximation, RL can apply to much larger state spaces than classical sequential optimization techniques such as dynamic programming. In addition, using simulations (sampling), RL can apply to systems that are too large or complicated to explicitly enumerate the next-state transition probabilities.
Related QuestionsMost RL work assumes the action space is discrete; what about continuous actions?
RL FAQIt is true that most RL work has considered discrete action spaces, but this was usually done for convenience, not as an essential limitation of the ideas; and there are exceptions. Nevertheless, it is often not obvious how to extend RL methods to continuous, or even large discrete, action spaces. The key problem is that RL methods typically involve a max or sum over elements of the action space, which is not feasible if the space is large or infinite.
Related QuestionsI am doing RL with a backpropagation neural network and it doesn't work; what should I do?
RL FAQIt is a common error to use a backpropagation neural network as the function approximator in one's first experiments with reinforcement learning, which almost always leads to an unsatisfying failure. The primary reason for the failure is that backpropation is fairly tricky to use effectively, doubly so in an online application like reinforcement learning.
