After July 14, it is completely limited to the peak of the current level.Through the above analysis, we find that the bottleneck of our system is the limit flow of the circle of friends.

Most data mining algorithms rely on numeric or categorical features, extracting numeric and categorical features from a data set, and selecting the best features.Features can be used for modeling, and models represent reality in an approximate way that machine mining algorithms can understandAnother advantage of featur
is to test a series of learned g and find the g that minimizes the Eout as the final output.The two methods will be explained in the next two sections. The final result obtained by the first method is as follows:Course Summary:In the past, when studying data mining courses, I also heard that we should not over-fitting, but the book does not seem to explain why o
1.1 Why Data MiningData mining transforms large datasets into knowledge.A data warehouse is a multi-heterogeneous data source that organizes storage in a single site in a unified pattern to support management decisions.Online analytical Processing (OLAP) is an analytical technique that has the ability to summarize, mer

Clustering Analysis algorithm Cluster analysis algorithm is to measure the similarity between individuals, is based on the individual data points in the distance of the geometric space to judge, the closer the distance, the more similar, the more easily categorized into a class. After the classification is initially defined, the algorithm determines how well the classification represents the point grouping by calculation, and then a

The predictions mainly include classification-dividing the sample into one of several predefined classes, regression-mapping the Crown Proxy network sample to a real-valued predictor variable; The description mainly includes clustering-dividing the sample into different classes (no predefined classes), and association rule Discovery-discovering the correlations of the different features in the dataset. Other articles in this series will explain these work in depth, if the reader is the first to
It's been years since I last ventured to answer "How to choose Data Mining Tools". This article mainly elaborates the following two core viewpoints:
1. There is no best tool, or rather, the best tool for everyone.
2. The most useful tools are those that can meet the vast majority of data mining tasks you need.
