Summary: What is data mining. What is machine learning. And how to do python data preprocessing. This article will lead us to understand data mining and machine learning technology, through the Taobao commodity case data preprocessing combat, through the iris case introduced a variety of classification algorithms. Intr

. Optimal interval classifierThe optimal interval classifier can be regarded as the predecessor of the support vector machine, and is a learning algorithm, which chooses the specific W and b to maximize the geometrical interval. The optimal classification interval is an optimization problem such as the following:That is, select Γ,w,b to maximize gamma, while satisfying the condition: the maximum geometry in

training on the basis of the known data samples, and the classification data model is used to predict the numerical data. Unsupervised learning is the clustering of data. Therefore, the main task of machine learning is classification.What issues do we need to consider when applying machine

implied variables obtained by the E step.Repeat 2 steps above until convergence.The formula is as follows:The derivation process of the Nether function in M-Step formula:A common example of the EM algorithm is the GMM model, where each sample is likely to be produced by K-Gaussian, except that each Gaussian produces a different probability, so each sample has a corresponding Gaussian distribution (one of the k's), at which point the implied variable is a Gaussian distribution corresponding to e

A Gentle Introduction to the Gradient boosting algorithm for machine learning by Jason Brownlee on September 9 in xgboost 0000Gradient boosting is one of the most powerful techniques for building predictive models.In this post you'll discover the gradient boosting machine learning algorithm and get a gentle introdu

Machine Learning notes of the Dragon Star program 　Preface In recent weeks, I spent some time learning the machine learning course of the Dragon Star program for the next summer vacation. For more information, see the appendix. Th

learning (temporal difference learning)In the case of enterprise Data application, the most commonly used is the model of supervised learning and unsupervised learning. In the field of image recognition, semi-supervised learning is a hot topic because of the large number of

argues that this limitation makes the attention mechanism completely unable to complete the corresponding learning function in some tasks. Whether this limitation can be broken. The article thinks that acitve memory mechanism can break the limitation of attention. In short, Active memory is decoding this step to rely on and access all memory, each step decoding the memory is different. Of course, this mech
