A long time ago to learn the SVM, always feel that is not to find the middle of the line, but some ambiguous, real programming time is a lump of paste, parameters randomly test, no discipline. Since this chapter has been re-learned, it is necessary to understand the areas that have not been understood before, do not work hard again ~ algorithm is very simple, if not learn, just because lazy ~ write this paragraph, just to remind yourselfThe following images are used in the courseware of Yang Yi

The formula adds a coefficient that we set ourselves, and we take 30 different values to see the change of W.STEP5:Ridge return:#岭回归def ridgeregression (data, L): Xmat = Mat (data) Ymat = Mat (l).

before, but you need to define T (Y) here:In addition, make:(t (y)) I represents the first element of the vector T (y), such as: (t (1)) 1=1 (T (1)) 2=01{.} is an indicator function, 1{true} = 1, 1{false} = 0(T (y)) i = 1{y = i}Thus, we can introduce the multivariate distribution of the exponential distribution family form:1.2 The goal is to predict the expectation of T (y), because T (y) is a vector, so the resulting output will also be a desired vector, where each element is:Corresponds to th

Windows azure platform articles This chapter describes how to configure a virtual machine database. The default data storage path for SQL 2012 of virtual machine is in disk C. As I introduced in the previous chapter, disk C can only support a maximum of 127 GB. disk C is very valuable for us. Therefore, for other non-system data, it is reasonable to save it to another drive letter (not a drive D. 1

Machine Learning-multiple linear regression and machine Linear Regression What is multivariate linear regression? In linear regression analysis, if there are two or more independent variablesMultivariable linear regression). If we want to predict the price of a house, the factors that affect the price may include area, number of bedrooms, number of floors, and age, we use x1, x2, x3, and x4 to represent the

Structure of class fileThere are two structures in Java's class file: unsigned numbers and tables. The smallest storage unit is 8 bytes.Unsigned numbers are the basic data types used to describe numbers, UTF-8 encoded strings, and index references.Represents a complex data structure that consists of multiple unsigned numbers.which Magic is the magic number, and the magic number takes up 4 bytes, what is the magic number to do? It actually means that the type of the file is a class file, no

The concept of extreme learning machineElm is a new fast learning algorithm, for TOW layer neural network, elm can randomly initialize input weights and biases and get corresponding output weights.For a single-hidden-layer neural network, suppose there are n arbitrary samples, where。 For a single hidden layer neural network with a hidden layer node, it can be expressed asWhere, for the activation function, the input weight, for the output weight, is the bias of the first hidden layer unit.The le
