Preface
For the time being, many of the methods in deep reinforcement learning are based on the previous enhanced learning algorithm, where the value function or policy Function policy functions are implemented with the substitution of deep neural networks. Therefore, this paper attempts to summarize the classical algorithm in

In reinforcement learning (v) using the sequential Difference method (TD), we discuss the method of solving the reinforcement learning prediction problem by using time series difference, but the solving process of the control algorithm is not in-depth, this paper gives a detailed discussion on the on-line control algor
: deep learning has made great progress in vision and speech, attributed to the ability to automatically extract high level features. The current reinforcement learning successfully combines the results of deep learning, that is, DQN, to get breakthrough on Atari games.However, the problem came (elicit motive motivatio
objectsThe class selector we use in CSS can also be used to get page elements in the DOM, but Document.getelementsbyclassname ("class name") has a strong compatibility problem, which is generally not necessary.3. Definition of Event 3.1 eventWhen we have finished fetching the page elements, we set the properties on the elements we get to them.At this point, the concept of events is involved.An event is a specific interaction moment that occurs in a document or browser window.Events need to trig

Custom attribute 6.1 You can add an attribute directly to the tag using inline, such as the following num attribute:Custom properties set in this way cannot get to the value set by the "event source. Property" method, and you can get the property value by Txt.getattribute ("num").6.2 You can also set the custom properties by JS.TXT.MM = "258"; is the ability to set a custom property by using JS.6.3 Object mode to set or remove label propertiesTxt.setattribute

Reinforcement LearningThe solution to the problem of control decision: to design a return function (reward functions), if the learning agent (such as the above four-legged robot, chess AI program) in the decision of a step, to obtain a better result, Then we give the agent some return (such as the return function result is positive), get poor results, then the return function is negative. For example, a qua

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
size or position of the element is not accurate.5. Get any element style you wantIf we want to get an attribute value for an element, we can use the offset series to get it, but if we need to get multiple property values, and can't determine what attributes we need to get, then we'll be more troublesome and unable to get what we want. Nor can we use the style["property name" method to get it, because this method cannot get the properties that are set in the inline format, but it is more limited

background: Strengthening learning and playing games
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.
