These topics are getting very hot nowadays because these learning algorithms can be used in several fields from software engineering to investment banking. Goal: learn a policy that maximize reward. RL focuses on the controlled learning process, where a machine learning algorithm is provided with a set of actions, parameters, and end values. Sequential decision making is needed to reach a goal, so time plays an important role in reinforcement problems (no IID assumption of the data holds good here) The agent's action affects the subsequent data it receives. Code link included at the end. AI-2, Assignment 2 - Reinforcement Learning. P(B|A) = (P(A|B) * P(B)) / P(A) Probability of B given A = … naive comes from the fact that features have been independently chosen from a distribution It does so by exploration and exploitation of knowledge it learns by repeated trials of maximizing the reward.

Naïve Bayes algorithm is a supervised learning algorithm, which is based on Bayes theorem and used for solving classification problems. . Reinforcement learning cannot produce reliable results without a good encoding, and encoder cannot be tuned properly without a good agent, since it must properly encode high-dimensional states in various stages of the environment . JEL Classification: D10, D14, G10. Reinforcement learning (RL) is the most widely used machine learning algorithm, besides supervised and unsupervised learning and the less common self-supervised and semi-supervised learning. discovering novel strategies is intractable with naive self-play exploration methods; and those strategies may not be effective when deployed in real-world play with humans. Naive Bayes. For each good action, the agent gets positive feedback, and for each bad action, the agent gets negative feedback or penalty. This is another naive approach which would give .
