First, the Cisco router to introduce the memory A router is similar to a computer in that it also has memory, operating system, configuration, and user interface, and the operating system in Cisco routers is calledInternet Operating System (Internetwork operating system) or iOS. The following is mainly about the storage of routers. ROM: Read-only memory contains a copy of the iOS being used by the router;Ram:ios the random access memory into shared and main memory. It is mainly used to store t

real life we tend to based on a number of features (multi-string numbers) to analyze one thing, each primitive feature we are regarded as a dimension (Dimension). For example, a student's academic performance depends on the scores of Chinese, maths, English and other courses to judge comprehensively, here each course is a dimension. When using two-time curves and multivariable (multidimensional) fitting, the number of features increases exponentially, and the feature number = Dimension ^2/2 Thi

Li Hongyi Teacher's course: Https://www.youtube.com/watch?v=W8XF3ME8G2I Teacher said, for the same observation/state (Atari game screen), also not necessarily will take the same action, because some actor is stochastic, select action has a certain randomness, this good understanding ... The teacher also said that even if actor take the same action, the reward and next state are not necessarily the same, because game itself has some randomness. I n

capabilities and work in areas where human experience is missing. In recent years, the use of intensive learning and training of the deep neural network has made rapid progress. These systems have surpassed the level of human players in video games, such as atari[6,7] and 3D virtual Games [8,9,10]. However, the most challenging areas of play in terms of human intelligence, such as Weiqi, are widely considered to be a major challenge in the field of A

call value iteration it. The reason is very well understood, policy iteration uses the Bellman equation to update value, and the last convergent value is Vπv_\pi is the value of the current policy (so called policy evaluation), The goal is to get a new policy for the latter policy improvement. The value iteration is used to update value using the Bellman optimal equation, and the last convergent value is v∗v_* is the optimal value in the current state. Therefore, as long as the final convergenc

under the strategy. The so-called policy is actually a series of action. That is sequential data.Reinforcement learning can be depicted in the following diagram by extracting an environment from the task to be completed, abstracting the state, the action, and the instantaneous reward (reward) that is accepted for performing the action.Reward Reward are usually recorded as Rt R_{t}, which represents the return reward value of the T-time step. All reinforcement learning is based on the reward hyp

Introduction to Reinforcement learning first, Markov decision process The formation of reinforcement learning algorithm theory can be traced back to the 780 's, in recent decades the reinforcement learning algorithm has been silently progressing, the real fire is the last few years. The representative event was the first demonstration by the DeepMind team in December 2013 that the machine used the enhanced learning algorithm to defeat human professionals in the

corporal punishment, these algorithms are punished when they make the wrong predictions, and they get rewarded when they make the right predictions-that's the point of reinforcement. Combining deep learning with enhanced algorithms can defeat human champions in Weiqi and Atari games. Although this does not sound convincing enough, it is far superior to their previous accomplishments, and the most advanced advances are now swift. Two reinforcement l

("42.33") // result = 42 The value returned by the function is an integer or a floating point. If there is no rounding, the decimal point and the number following it will be discarded. ParseFloat () returns a floating point number (if it is an integer, it returns an integer), for example: ParseFloat ("42") // result = 42 ParseFloat ("42.33") // result = 42.33 If you want to convert a string somewhere, you just need to insert the function to the beginning. For example: 3 + 3 + parseInt ("3") //
