In the Linux world, there are several different ways you can choose to make a speech. For example, with a large number of multimedia display, visual impact of excellent impress.js, specifically for latex users to provide Beamer, and so on. And if you're struggling to find a simple way to create and present a text presentation, MDP can help you achieve it.
What is MDP?
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 strategy. There are three basic solutions:
Dynamic programming method (programming methods)

MDP: Markov decision-making processes (Markov decision process)Defined:A Markov model includes the following sections
State set S (states)
Action set A (Actions)
Rewards and punishments functions R (reward function)
Under state s , the effect function of a action is performed T
We assume that the effect of performing action a is only relevant to the current state, regardless of the previous history state.Action Representations: divide
MDP: Markov decision-making processes (Markov decision process)Behrman equation:In the previous section, this is a model of deterministic action. If the model of the random action, it should be expressed asThat is, there are multiple states after performing an action, and the probability is multiplied by the value function to get the formula.Therefore, the current state optimal execution action isThere is a vπ (S) for each state, so for each step, you

As you prepare a speech, your mind may be dominated by an illustrated, flamboyant presentation of the artwork. Admittedly, no one would deny the positive effect of a vivid speech. However, not all speeches require the quality of TED talk. More often than not, speeches only convey specific information. And this, the use of text information is sufficient to complete. In this case, your time can be better spent gathering and verifying information, rather than looking for good-looking pictures on Go
Several Problems in the Display Section have been clarified through actual tests over the past few days, mainly including the usage of each module and the calling process of several modules in the Hal layer. The problem is described as follows:
0. surfaceflinger Main Functions
Surfaceflinger is only responsible for the control of merge surface. For example, to calculate the overlapping areas of two surfaces, as for the content to be displayed on the surface, it is calculated through skia, OpenGL

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 quadruped robot, if he moves a step forward (close to the target), then the return function i

Usage:
Copy Code code as follows:

Model-free Control. The so-called model-free refers to the absence of a given MDP (that is, MDP is unknown, not even the MDP process).
It is hoped that the control is not given in the case of MDP (ideally the policy is not given, optimise the value function of an unknown
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.
