coursera introduction to machine learning

If you only want to read a book, then recommend Bishop's Prml, full name pattern recognition and Machine Learning. This book is a machine learning Bible, especially for the Bayesian method, the introduction is very perfect. The book is also a textbook for postgraduate course

examples. Algorithms of the Intelligent Web (Smart Web algorithm) PDFAuthor Haralambos Marmanis, Dmitry Babenko. The formula in this book is a little bit more than "collective intelligence programming", the example of which is mostly the application on the Internet, to see the name. The disadvantage is that the matching code inside is BeanShell and not python or anything else. In general, this book is still suitable for beginners, and the same need to read the same as the previous one, if you

To learn about machine learning, you must master a few mathematical knowledge. Otherwise, you will be confused (Allah was in this state before ). Among them, data distribution, maximum likelihood (and several methods for extreme values), deviation and variance trade-offs, as well as feature selection, model selection, and hybrid model are all particularly important. Here I will take you to review the releva

of a nonlinear function sigmoid, and the process of solving the parameters can be accomplished by the optimization algorithm. In the optimization algorithm, the gradient ascending algorithm is the most common one, and the gradient ascending algorithm can be simplified to the random gradient ascending algorithm.2.SVM (supported vector machines) Support vectors machine:Advantages : The generalization error rate is low, the calculation cost is small, the result is easy to explain.　　　　cons : Sensit

the reduced dimension algorithm attempts to use less information to summarize or interpret the data in an unsupervised learning way. Such algorithms can be used to visualize high-dimensional data or to simplify data for supervised learning. Common algorithms include: PCA (Principle Component Analysis, PCA), Partial least squares regression (partial Least Square regression,pls), Sammon mappings, Multidimens

SVM is a widely used classifier, the full name of support vector machines , that is, SVM, in the absence of learning, my understanding of this classifier Chinese character is support/vector machines, after learning, Only to know that the original name is the support vector/machine, I understand this classifier is: by the sparse nature of a series of support vecto

In addition to chapter 1th Introduction and Final Chapter summary, each chapter introduces a method. The narrative begins with specific problems or examples, clarifies ideas, gives the nec

randomly groups the data to the extent that training intensive accounts for 70% of the original data (this ratio can vary depending on the situation), and the test error is used as the criterion when selecting the model. The question comes from the Stanford University Machine Learning course on Coursera, which is described as follows: the size and price of the

Recently is a period of idle, do not want to waste, remember before there is a collection of machine learning link Andrew ng NetEase public class, of which the overfiting part of the group will report involved, these days have time to decide to learn this course, at least a superficial understanding.Originally wanted to go online to check machine

calculates the accuracy of the entire system at this time: As shown in, text recognition consists of four parts. Now we can find the system accuracy after optimization for each part. The question is, how can we improve the accuracy of the entire system? We can see from the table that, if we have optimized the text moderation part, the accuracy will be72%Add89%If we optimize the character segmentation, the accuracy is only from89%To90%If character recognition is optimized90%To100%In contr

Anyone who knows a little bit about supervised machine learning will know that we first train the training model, then test the model effect on the test set, and finally deploy the algorithm on the unknown data set. However, our goal is to hope that the algorithm has a good classification effect on the unknown data set (that is, the lowest generalization error), why the model with the least training error w

times confusing people are, many algorithms are a kind of algorithm, and some algorithms are extended from other algorithms. Here, we from two aspects to introduce to you, the first aspect is the way of learning, the second aspect is the classification of the algorithm.Bloggers in the original based on the introduction of genetic algorithm (2.9), so that this blog post contains a more comprehensive
