data (such as which friends and you hit it off). From the above example, we can see that machine learning is actually the imitation of human intelligence, but also the way to achieve human and higher intelligence.(What's the goods?) What does he basically have?(rather difficult machine

instruction represents one or more operations. Give a simple example, and you can use it in your life. Now make a small game, a on the paper randomly wrote a 1 to 100 integer, b to guess, guess the game is over, guess the wrong word a will tell B guess small or big. So what will b do, the first time you must guess 50, guess the middle number. Why is it? Because this is the worst case (log2100log2100) can be guessed six or seven times. This is a binar

. such as stock forecasts. Clustering (clustering): Data is not labeled, but there are some similarity metrics that can be used to classify data according to these criteria. For example, in a pile of photos that do not give a name, the photos of the same person are automatically gathered together. Rule extraction: Discover the statistical relationships between attributes in the data, not just predict things. such as beer and diapers.

Getting started with Python machine learning(Reader Note: This is an introductory guide to machine learning, and the author outlines the pros and cons of starting machine learning with Python, and the Python package used to start

Brief introductionBefore I introduce machine learning, I would like to start by listing some examples of machine learning: junk e-mail detection: Identifies what is spam and what is not, based on the messages in the mailbox. Such a model can help categorize spam and non-spam messages by programs. This

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

problem, just a career change, it means no problem.Several other packages can also be detected using the method above.To view the version of the package that you installed, you can use the following command:1. If there is pip.exe:PIP List2.Anaconda:Conda List　　The entire installation and configuration process I have said so much, this process can fail many times ... But in order to learn more things, still have to be patient step by stage test and find the reason.Note: I use Windows 10, and may
