Machine learning, relationships with several related fields. Mainly by the performance of the relationship:The statistical method can be used to realize machine learning (machines learning), while machine
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

The analysis and mining of these data can not only provide decision support

Again thanks to the little turtle Brother's python video Let me last year in the next semester of the introduction of programming, fell in love with the programming of the language, because it is biased statistics, after the internship decided to put the direction of data mining, more and more found the importance of specialized courses. In the days

The steps can be summarized as follows:
Obtains a finite set of training data;
Determine the hypothetical space that contains all possible models, that is, the set of learning models;

If a collection of items is a frequent collection, then any non-empty set of it is also a frequent set;Aprioir need to scan the project table many times, starting from a project to scan, to remove those not frequent items, the resulting collection is called L, and then each element in the L is self-assembled, generating a collection of items more than the last scan, the collection is called C, and then the scan t

products, and so on, can be abstracted into vectors to allow the computer to know the distance between two properties. For example: We believe that 18-year-olds are closer to the 24-year-old than the 12-year-old, which is closer to the product than the computer, and so on.as long as the real-world objects can be abstracted into vectors, you can use the K-means algorithm to classify .In the "K-mean Clustering (K-means)" This article cited a very good application example, the author made a vector
