[RL] Q learning algorithm based on neural network (deep learning) (DQN)

DQN introduction DQN(Deep Q-Learning)It is the combination of deep learning and reinforcement learning Q-table He is too big to build words to use DQN Is a good choice. DQN algorithm mainly uses experience replay (experience pool) to realize the convergence of value function. The Deep Q-learning method is used to iteratively update Q (s, ...

[algorithm note] stack and queue

Basic knowledge Stack The stack provides interfaces such as push and pop, and all elements must comply with the first in and last out rule. Therefore, the stack does not provide access function or iterator. Stacks in STL are often not classified as containers, but as container adapter s.The bottom implementation of stack can be vector, deque ...
