At present, machine learning is one of the hottest technologies in the industry.With the rapid development of computer and network, machine learning plays a more and more important role in our life and work, and it is changing our life and work. From the daily use of the camera, daily use of the search engine, online e

hypothesis could not being built up,Generlly the number of hypothesisThat can is built is less than a^b.Let's come back to the inequlity, we can prove it mathematically thatif M can be replaced by a polynomial, which means the number of hypothesis in a set are not infinite and then we can declar E that learning was feasible using this hypothesis set.There is a new statement this wil be proved next lecture, if the maxnum of hypothesis are less than it

Algorithms have become an important part of our daily lives, and they almost appear in any area of business. Gartner, the research firm, says the phenomenon is "algorithmic commerce", where algorithmic commerce is changing the way we operate and manage companies. Now you can buy these various algorithms for each business area on the "algorithmic market". The algorithmic market provides developers with more than 800 algorithms, including sound and visual processing,

An example of

With the growth of application data, statistical analysis and machine learning are becoming a big challenge in large datasets. Currently, there are many languages/libraries for statistical analysis/machine learning, such as the R language designed for

are two issues to note:1, if the data is linearly non-divided.When the data is linearly non-divided, we can also use the above method, but will come to an unacceptable solution, at this time we can detect whether the solution is valid to determine whether our data can be divided.2. What happens if W0 exists in Z?In our previous assumptions, W0 represents a const

Netfei is a DVD leasing company. by increasing its sales by 10%, it can earn 1 million RMB in revenue, which is very impressive. How to: predict consumers' ratings for movies? (Increase the predicted value by 10 percentage points through their own systems) if the recommendations you provide to consumers are very accurate, the consumers will be very satisfied. The essence of machine learning: 1. An existin

This lesson mainly describes the processing of linear models. Including: 1. Input Representation) 2. Linear Classification) 3. Linear Regression) 4. nonlinear transformation) The author believes that to test the availability of a model, it is to use real data to do a good job. To explain how to apply linear models, the author uses linear models to solve the problem of post office data identification: Becau
