This chapter details the operation of the Q-Learning algorithm, one of the most widely used in algorithms Reinforcement Learning. The components of the algorithm and its demonstration through pseudocode are pre
The pseudocode for Q-learning is given in Algorithm 4. Algorithm 4 Q-learning algorithm. Initialization: Arbitrary initialization for all s∈ S, a∈ A, except that Q(terminal, .) = 0 for each episode do Initialize s repeat Choose a∈ A from s using policy derived from Q Take action a...
So now that we understood what are Q-Learning, Q-Function, and Q-Table, let’s dive deeper into the Q-Learning algorithm 5.2. The Q-Learning algorithm This is the Q-Learning pseudocode, let’s study each part, then we’ll see how it works with a simple example before implementing it....
Here is the pseudocode for a 3 layer neural network, as reference.You should use a learning rate (eta) of 0.1minibatch_gd(epoch, w1, w2, w3, w4, b1, b2, b3, b4, x_train, y_train, num_classes, shuffle=True)This function will implement your minibatch gradient descent (model ...
Q-learning Agent TrainedAgent In this part of the assignment, you will create a snake agent to learn how to get food as many as possible without dying. In order to do this, you must use Q-learning. Implement the TD Q-learning algorithm and train it on the MDP outlined above. ...
Just from looking at the structure of this pseudocode, what might go wrong if you try to do this with a deep neural network to represent Q Phi. So maybe your initial policy is pretty bad. So the data you collect in step 1 might never visit states with high-reward. So that would ...

Pseudocode for Q-Learning with TD Update: The updated algorithms, incorporating double Q-learning and dynamic parameter adjustment, are detailed in Algorithms 1 and 2. Through repeated training, each node learns to choose optimal encryption levels based on its current energy state and the perceived ...
As usual in Q-learning, the exploration parameters can be reduced during the system’s lifetime, favoring exploration in the early stages and exploitation in later stages to improve performance and convergence. The pseudocode for rl4dtn is shown in Algorithm 2. The entry point is on line 16,...
The following pseudocode summarizes how Q-learning works: 3.3. Example Let’s see a simple example below to see how Q-learning works. Our agent is a rat that has to cross a maze and reach the end (its house) point. There are mines in the maze, and the rat can only move one tile...
