WebJul 13, 2024 · Q-Learning is part of so-called tabular solutions to reinforcement learning, or to be more precise it is one kind of Temporal-Difference algorithms. These types of algorithms don’t model the whole environment and … WebJul 12, 2024 · Shortcut Maze Consider a case called shortcut maze, in which the environment is dynamically changing. An agent starts at S and aims to reach G as fast as possible, and the black grey blocks are areas that the agent can not pass through. WebThe main idea behind Q-learning is that if we had a function Q^*: State \times Action \rightarrow \mathbb {R} Q∗: State× Action → R, that could tell us what our return would be, if we were to take an action in a given state, then we could easily construct a policy that maximizes our rewards: protein shake for suhoor

Private Equity Interview Course. 9 LBO Modeling Tests + … Q-learning is a model-free reinforcement learning algorithm to learn the value of an action in a particular state. It does not require a model of the environment (hence "model-free"), and it can handle problems with stochastic transitions and rewards without requiring adaptations. For any finite Markov decision … See more Reinforcement learning involves an agent, a set of states $${\displaystyle S}$$, and a set $${\displaystyle A}$$ of actions per state. By performing an action $${\displaystyle a\in A}$$, the agent transitions from … See more Learning rate The learning rate or step size determines to what extent newly acquired information overrides old information. A factor of 0 makes the agent learn nothing (exclusively exploiting prior knowledge), while a factor of 1 makes the … See more Q-learning was introduced by Chris Watkins in 1989. A convergence proof was presented by Watkins and Peter Dayan in 1992. Watkins was addressing “Learning from delayed rewards”, the title of his PhD thesis. Eight years … See more The standard Q-learning algorithm (using a $${\displaystyle Q}$$ table) applies only to discrete action and state spaces. Discretization of these values leads to inefficient learning, largely due to the curse of dimensionality. However, there are adaptations of Q … See more After $${\displaystyle \Delta t}$$ steps into the future the agent will decide some next step. The weight for this step is calculated as $${\displaystyle \gamma ^{\Delta t}}$$, where $${\displaystyle \gamma }$$ (the discount factor) is a number between 0 and 1 ( See more Q-learning at its simplest stores data in tables. This approach falters with increasing numbers of states/actions since the likelihood of the agent visiting a particular state and … See more Deep Q-learning The DeepMind system used a deep convolutional neural network, with layers of tiled convolutional filters to mimic the effects of receptive fields.

"WebQ-learning is probably the most popular RL technique for beginners, but can only solve very simple toy problems with a discrete state space, such as a 2D maze. It is not very effective in addressing problems with a continuous state space, even simple ones, such as the Cartpole. It might solve them but would take much longer than other RL methods.
