training of several classifiers, the tuple that was incorrectly categorized in the previous classifier, is increased in weight so that it is more "concerned" in the classifier that is later established.The final classification is also voted by all classifiers, voting weights depend on the accuracy of the classifierAdaBoost algorithmAdvantages and disadvantages of the lifting algorithmCan get a higher accuracy rate than bagging.Easy to over fitStochastic forest (random Forest) algorithmComposed

). The course content is basically code-based programming, there will be a small amount of deep learning theoretical content. The course starts with some of the most basic knowledge from TensorFlow's most basic diagrams (graphs), sessions (session), tensor (tensor), variables (Variable), and gradually talks about the basics of TensorFlow, And the use of CNN and LSTM in TensorFlow. After the course, we will take you to do a few practical projects, such as training your own model to do image recog

"Furnace-smelting AI" machine learning 019-Project case: Estimating traffic flow using the SVM regression(Python libraries and version numbers used in this article: Python 3.5, Numpy 1.14, Scikit-learn 0.19, matplotlib 2.2)As we all know, SVM is a good classifier, not only for linear classification models, but also for non-linear models, but on the other hand, SVM can be used not only to solve classification problems, but also to solve regression prob

1. The idea of split-smelting algorithm is to divide a complex computational problem into small scale, simple calculation, and then synthesize each small problem to get the answer of the final question.2. The execution process of the split-metallurgical algorithm For a problem with the magic N, if the problem can be easily resolved, then directly resolve, otherwise perform the following steps. This is decomposed into M-small sub-problems,

and BPRBF has only one hidden layer, BP can be multilayerThe RBF hidden layer and output layer use different activation functions , BP is the sameThe characteristics of the activation function are different, the RBF chooses the nonlinear function of local exponential attenuation (emphasizing local), and BP uses the input sample to take the inner product of the weight vector as the independent variable, and the activation function uses the sigmoid ring limiting function (emphasizing the global).

Least squares solution for multivariate linear regression (unbiased estimation)Ridge return (Ridge regression,rr)When there is a complex collinearity between the independent variables, |x′x|≈0, we envisage adding a normal number matrix Ki to X′x, (k>0),Then the degree of x′x+ki approaching singularity would be much smaller than X′x's proximity to singularity.The ridge regression as β estimate should be more stable than the least squares estimation, and when the k=0 Ridge regression estimate is t
