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, casually come up with a kind of can be called Classic algorithm, they in the field of dat

classifier.8,knn:k-nearest neighbor ClassificationK Nearest neighbor (k-nearest NEIGHBOR,KNN) classification algorithm is a theoretically mature method and one of the simplest machine learning algorithms. The idea of this approach is that if a sample is in the K most similar in the feature space (that is, the nearest neighbor in the feature space) Most of the samples belong to a category, then the sample b

Summary of advantages and disadvantages of machine learning common algorithmsk Nearest Neighbor : The algorithm uses the method of measuring the distance between different eigenvalues to classify.Advantages:1. Easy to use, easy to understand, high precision, mature theory, can be used to do classification can also be used to do regression;2. Can be used for numerical data and discrete data;3. The training t

Status of machine learning: 1, China's traditional industry is not ready to use artificial intelligence technology, many traditional industries do not regard it as a strategic focus; 2, to set up artificial intelligence strategy of enterprises, the lack of talent is its main shackles; 3, in this field, especially in the robotics level with developed countries far apart. We make effective advances because we
