converge or even diverge. .One thing worth noting:As we approach the local minimum, the guide values will automatically become smaller, so the gradient drop will automatically take a smaller amplitude, which is the practice of gradient descent. So there's actually no need to reduce the alpha in addition, we need a fixed (constant) learning rate α. 4. Gradient Descent linear regression (Gradient descent for Linear Regression) This is the method of us

I often use toplanguageSome books are recommended in the discussion group, and we often ask the ox people to collect relevant information, such as artificial intelligence, machine learning, natural language processing, and Knowledge Discovery (especially Data Mining), Information RetrievalThese are undoubtedly CSThe most interesting branch in the field (also closely related to each other). Here we will clas

, transformation, measurement, division and so on in Lie groups are important for the study of algebraic methods in learning.9 , graph theory (graph theory)Figure, due to its strong ability to express various relationships and elegant theory, efficient algorithm, more and more popular in the field of learning. Classical graph theory, one of the most important applications in

amounts of seemingly unrelated data processing, so need data mining technology to extract a variety of data and variables of the relationship between, so as to refine the data.Data mining is essentially a basis for machine learning and artificial intelligence, and his main goal is to extract the superset information from a variety of data sources, and then merge that information into patterns and relations

thorough search. Many greedy algorithms are like this, as will be mentioned later. Decision Tree Algorithm. The previous inductive bias is called Limited offsetThe latter is called Preferred offset. When studying other inductive inference methods, it is necessary to keep in mind the existence and strength of such inductive bias. If an algorithm is more biased, the more inductive it can be, and more instances are not found. Of course, the correctness

training, but as a punishment or reward for the environment. Typical problems are system and robot control. Example of an algorithm packageQ-Learning and sequential differential learning (temporal difference learning).Algorithmic similarityAccording to the function and form similarity of the algorithm, we can classify the algorithm, for example, tree-based algor

Here we assume that Q is given (UNIFORM/SW) **********************************************The MH sampling process is as follows:1, given assignment, according to the F to find Pi (Assignment)2, according to the above formula to calculate the acceptance probability a3, decide whether to accept, complete the sampling update

On Github, Afshinea contributed a memo to the classic Stanford CS229 Course, which included supervised learning, unsupervised learning, and knowledge of probability and statistics, linear algebra, and calculus for further studies.

recurrent neural Network (RNN). It memorizes any commonalities on the network and serves like a memory later. Formally, the argument states that;Let us assume, the persistence or repetition of a reverberatory activity (or "trace") tends to induce lasting cellular Changes that add-to-its stability .... When an axon of cell a was near enough to excite a cell B and repeatedly or persistently takes part I n firing it, some growth process or metabolic change takes place in one or both cells such tha
