boosting analysis, but it still cannot be explained that when the training error is 0, its generalization error is still decreasing, later scholars have raised the question of margin bound. In addition, the method of better understanding of boosing from another perspective is greedy boosting, that is, the process of searching for sample weight D and weak classifier weight W is a greedy process. Finally, th

Such algorithms can be used to v

Machine Learning Algorithm Introduction _ Machine learning

. The typical algorithm in it is the C5.0 Rules, a variant based on the decision tree. Because the decision tree is a tree-like structure, it still has some difficulty in understanding. So it extracts the result of the decision tree to form a small rule consisting of two or three conditions. Working with stories: It is slightly less accurate than the decision tree and is rarely used by people. It is probably necessary to provide clear rules to explain the decision.Propulsion algorithm (

It is the core of computer vision, which is widely used in practice. The traditional method of image classification is feature description and detection, such traditional methods may be effective for some simple image classification, but the tradit

the probability of getting these documents .)The difference between Bagging and boosting is that the training set selection of bagging is random, and the training sets of each round are independent of each other, while the training set of boostlng is independent, the selection of training sets is related to the learning results of the previous rounds. The prediction functions of bagging have no weight, whi

Algorithm in Machine Learning (1)-decision tree model combination: Random forest and gbdt

have been many important iccv conferences, such as iccv.ArticleIt is related to boosting and random forest. Model combination + Decision Tree algorithms have two basic forms: Random forest and gbdt (gradient boost demo-tree ), other newer model combinations and Decision Tree algorithms come from the extensions of these two algorithms. This article focuses mainly on gbdt. It is only a rough mention of random forest because it is relatively simple. Be

Machine learning 00: How to get started with Python machine learning

We all know that machine learning is a very comprehensive research subject, which requires a high level of mathematics knowledge. Therefore, for non-academic professional programmers, if you want to get started machine learning, the best direction is to trigger from the practice.PythonThe ecology I learned is very help

posterior probabilities.GDBT:GBDT (Gradient boosting decision tree), also known as MART (multiple Additive Regression tree), seems to be used more internally in Ali (so Ali algorithm post interview may ask), It is an iterative decision tree algorithm, which consists of multiple decision trees, and the output of all the trees is summed up as the final answer. It is considered to be a strong generalization capability (generalization) algorithm with SVM
