For autonomous Vehicles (AV), to operate in a truly autonomous way in future intelligent transportation systems, it must be able to handle the data collected through a large number of sensors and communication links. This is essential to reduce the likelihood of vehicle collisions and to improve traffic flow on the road. However, this dependence on
Dueling Network architectures for deep reinforcement learningICML Best PaperAbsrtact: The contribution point of this paper is mainly in the DQN network structure, the features of convolutional neural network are divided into two paths, namely: the state value function and the State-dependent action Advantage function.. The main feature of this design is generalize learning across actions without imposing an
positive) and get a poor result, then the return function will be negative. For example, if a four-legged robot takes a step forward (approaching the target), the return function is positive and the return function is negative. If we can evaluate each step and obtain the corresponding return function, we can easily find the path with the highest return value (the maximum sum of the return values in each step ), it is considered to be the best path.

As we have already said, the aim of reinforcement learning is to solve the optimal strategy of Markov decision making process (MDP) so that it can obtain the maximum vπ value in any initial state. (This paper does not consider enhanced learning in non-Markov environments and incomplete observable Markov decision Processes (POMDP).)
So how to solve the optimal str

The simulator (model or emulator) outputs an image and an award with an action (action) as input.
A single image does not fully understand the current state of the agent, so it has to combine the information of the action with the state sequence.
The objective of the agent is to select actions in a certain way and intersect with the simulator to maximize future rewards.

In the previous depth Enhancement Study Series, we have analyzed the DQN algorithm in detail, a value based algorithm, then today, we are working with you to analyze another algorithm in depth enhancement learning, that is, based on the policy gradient policy gradient algorithm. The actor-critic algorithm combined with the value based algorithm is the most effective depth-enhanced learning algorit
following is a quote from the blog "Evolutionary Strategy optimization algorithm CEM (cross Entropy Method)" [3].
Cem can also be used to solve Markov decision-making processes, that is, to strengthen learning problems. We know that reinforcement learning is also a dynamic planning process in which an action is selected in a certain state as if a path is selecte

Monte Carlo is a kind of general algorithm, the idea is to approach the real by random sampling, here only introduced in the reinforcement learning application.The initial idea should be to run multiple cycles in succession, such as after two times (s, a), and calculates the corresponding GT, then Q (s,a) to take the average on it, but in fact, in order to optimize the strategy o

1 Preface
Deep reinforcement learning can be said to be the most advanced research direction in the field of depth learning, the goal of which is to make the robot have the ability of decision-making and motion control. The machine flexibility that human beings create is far lower than some low-level organisms, such as bees. DRL is to do this, but the key is to
