gradient descent algorithm: linear regression Model: Linear hypothesis:Squared difference cost function:By substituting each formula, the θ0 and θ1 are respectively biased:By substituting the partial derivative into the gradient descent algorithm, we can realize the process of finding the local optimal solution.The cost function of linear regression is always a convex function, so the gradient descent algorithm only has a minimum value after execution." Batch " gradient descent: use
Recent research on this one thing-the limit learning machine. In many problems, I often encounter two problems, one is classification, the other is regression. To put it simply, the classification is to label a bunch of numbers, and the regression is to turn a number into a number. Here we need to deal with the general dimension of the data is relatively high, in dealing with these two types of problems, the simplest way is weighted. The weight
browsed by users of the China Netcom line, the webpage file size will inevitably affect the viewer's feelings. Using Xhtml to build Web pages helps you solve this problem. After my tests, we can achieve the same purpose. The size of web pages built using Xhtml is about 1/2 less than that built using traditional table methods. I believe many people will like the slim MM. 2. How to get started with learners of different levels After feeling the above p

Moving DL we have six months of time, accumulated a certain experience, experiments, also DL has some of their own ideas and understanding. Have wanted to expand and deepen the DL related aspects of some knowledge.Then saw an MIT press related to the publication DL book http://www.iro.umontreal.ca/~bengioy/dlbook/, so you have to read this book and then make some notes to save some knowledge of the idea. This series of blog will be note-type, what is bad to write about the vast number of Bo frie
