Internationally authoritative academic organization the IEEE International Conference on Data Mining (ICDM) selected ten classic algorithms for data Mining in December 2006: C4.5, K-means, SVM, Apriori, EM , PageRank, AdaBoost, KNN, Naive Bayes, and CART.Not only the top ten algorithms selected, in fact, participate in the selection of the 18 algorithms, in fact,

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

More SVM Multi-classification application introduction, reference ' SVM Multi-Class classification method 'In the previous method we need to train n classifiers, and the first classifier is to determine whether the new data belongs to the classification I or to its complement (except for the N-1 classification of i). The latter way we need to train N * (n–1)/2 classifiers, the classifier (I,J) is able to determine whether a point belongs to I or J, and whe

The degree of support is used to measure how often a collection appears in the original data.2.10 Fp-growth algorithm:Description: Fp-growth is also an algorithm for discovering frequent itemsets, and he uses the structure of the FP tree to store building elements, and other apriori

Original: http://dataunion.org/13451.htmlXbinworld Introduction:In the field of machine learning, the so-called dimensionality reduction refers to the mapping of data points in the original high-dimensional space to the low-dimensional space. The essence of dimensionality is to learn a mapping function f:x->y, where x is the expression of the original data point, which is currently used at most in vector re

(i) Understanding decision Trees1, decision tree Classification principleRecent surveys have shown that decision trees are also the most frequently used data mining algorithms, and the concept is simple. One of the most important reasons why a decision tree algorithm is so popular is that the user does not have to understand the machine learning algorithm, nor do

Heuristic Optimization methodHeuristic method refers to the method that people take when they solve the problem and find it according to the rule of experience. It is characterized by the use of past experience in the solution of problems, th

equal to the distance between the other two. This red line is the hyperplane that SVM is looking for in two-dimensional situations. It is used for binary classification data. The point supporting the other two online is the so-called support vector. We can see that there is no sample in the middle of the hyperplane and the other two lines. After finding this hyperplane, we use the mathematical representation of the hyperplane data to perform binary classification of the sample data, which is th

Learning machine learning algorithms is really a headache, we have so many papers, books, websites can be consulted, they are either refined mathematical description (mathematically), or a step-by-Step text Introduction (textually). If you're lucky enough, you might find some pseudo-code. If the character breaks out, y

Machines (SVM), referred to as the SV Machine (the general abbreviation in the paper). It is a supervised learning method, which is widely used in statistical classification and regression analysis. Support Vector machines map vectors to a higher dimensional space, where a maximum interval of hyperspace is established in this space. On both sides of the super plane that separates the data, there are two su

Scene abstraction (it is through the existing data, to dig out the business scenarios can be applied.) Machine learning is primarily used to address scenarios including two classification, multi-classification, clustering, and regression.C. Algorithm se

It is characterized by the use of past experience in the solution of problems, the selection of methods that have been effective, rather than the systematic and determined steps to seek answers. There are many kinds of heuristic optimization methods, including classical simulated annealing method, genetic algorithm, ant colony algorithm, particle swarm algorithm and so on.There is also a special optimization algorithm called multi-Objective optimization algorithm, which is mainly
