of a nonlinear function sigmoid, and the process of solving the parameters can be accomplished by the optimization algorithm. In the optimization algorithm, the gradient ascending algorithm is the most common one, and the gradient ascending algorithm can be simplified to the random gradient ascending algorithm.2.SVM (supported vector machines) Support vectors machine:Advantages : The generalization error rate is low, the calculation cost is small, the result is easy to explain.　　　　cons : Sensit

~ ~): Machine learning, data mining (the second half of the main entry): "Introduction to Data Mining" read a few chapters, feel good. Read the review again.

playing the game until it was able to win. This doesn ' t is only apply to games, it also true of programs which perform classification and prediction. Classification is the process whereby a, can recognize and categorize things from a dataset including from Visual D ATA and measurement data. Prediction (known as regression in statistics) are where a machine can guess (predict) the value of something based

are pros and cons. This also gives us a large part of the time to explore.I began to develop a learning plan, collect information, watch the video, hope to understand these things in theory, slowly to practice them, and finally use. Well, it looks good. The idea is really hardships, and I finally failed to make it through the road. Theoretical knowledge involves, probability theory, Mathematical statistics

decision model can help the program provide support for financial analysis. Customer Segmentation: Identifies which users will be turned into the payment user for the product, and which will not, based on the behavior patterns of the user during the probation period and the behavior of all users in the past. Such a decision model can help the program with user intervention to persuade users to make early payments or better participate in product trials. Shape identification: Determi

First, Introduction1. Concept : The field of study that gives computers the ability to learn without being explicitly programmed. --an older, informal definition by Arthur Samuel (for tasks that cannot be programmed directly to enable the machine to learn) "A computer program was said to learn from experience E with respect to some class of tasks T and performance measure P, if Its performance on tasks in T, as measured by P, improves wit

To learn about machine learning, you must master a few mathematical knowledge. Otherwise, you will be confused (Allah was in this state before ). Among them, data distribution, maximum likelihood (and several methods for extreme values), deviation and variance trade-offs, as well as feature selection, model selection, and hybrid model are all particularly important. Here I will take you to review the releva

learning more effective, able to build a more intelligent system. We all agree that intelligence is an inevitable trend in the development of computer science, making our computers more and more intelligent. In this process, we must have a very powerful means. So far, in other fields of artificial intelligence, we find that the most powerful means may be based on data. Machine
