Stanford ml Open Course Notes 15In the previous note, we talked about PCA ). PCA is a direct dimensionality reduction method. It solves feature values and feature vectors and selects feature vectors with larger feature values to achieve dimensionality reduction.This article continues with the topic of PCA, including one application of PCA-LSI (Latent Semantic Indexing, implicit semantic index) and one implementation of PCA-SVD (Singular Value Decompos

It is believed that every webmaster knows that spiders crawl through the HTML code of the website and crawl the content of the website, and then give further feedback to the search engine to get the score, in order to give the ranking. Then in these processes we need to clearly describe the core theme of our site, but also is usually said title titles. Then we can use some HTML tags to further attract spiders, so that the key words better by spiders to understand the search engine to get a good

equivalent to "Least Squares. 7.3.1 Maximum Likelihood Estimation derivation In the following derivation, note that the "format" of x and W is very simple. Note that when processing "vectors", the standards are column vectors. If a book appears in the form of a single vector, you can only say: Throw it. Detailed derivation: 7.3.2 ry After finding W, the ry of y_hat = w'x is that y_hat is the projection point of Y in the Space Formed by X columns ". 7.3.3 convex Convexity Only when the funct

Generally, classification (or regression) is divided into two types: Parameter Learning and instance-based learning. The form of parameter learning is to learn the parameters of the corresponding model through a pile of training data, and then the training data is useless. For new data, the learned parameters can be used to draw a conclusion; Instance-based learning (also called memory-Based Learning) also uses training data such as KNN algorithm during prediction. Instance-based learning gene

I believe that the mathematics of the question of great and small, the reason why we are interested, because it can make our daily problems idealized. "Polya," Mathematics and Conjecture ", Volume One, page 133th we will see that many practical problems and mathematical problems can be attributed to all kinds of extreme problems

: Constructing a classification tree with the fastest descending entropy valueA decision tree is a tree structure in which each internal node represents a test on an attribute, each branch represents a test output, and each leaf node represents a category. The top-down recursive method is used to select the feature with the greatest information gain as the current splitting feature.6 SVM: Constructing super plane, classifying nonlinear data7 K-means: Calculating centroid, clustering without tag

Everything is difficult at the beginning, as the first blog, learn not to be easy to understand, fun, but to honestly make things clear.The thing that originated from the Kaggle competition was generously opening the source on GitHub, and Kaggle was very thoughtful to sort out these excellent solutions and implementations.
