サポートベクターマシン(support vector machine:SVM)の基礎 - HELLO CYBERNETICS
線形識別器の代表格としてサポートベクターマシンを取り上げます。 機械学習で一躍有名となった手法の1つで、ディープラーニングが流行る以前は「え、まだニューラルネットやっているの？時代はサポートベクターマシンでしょ」と言った雰囲気でした。今はなぜか逆転して「まだサポートベクターマシンやってるの？」と言う人が実際にいるのですが（笑）、ディープラーニングの設計・学習の手間などを考えるとサポートベクターマシンはまだまだ捨てたものではありません。転移学習などでも応用が効きますしね。 SVMはマージン最大化という考えで、高い汎化性能を持つことが知られています。今回は、SVMがどのような考えでデータを識別するように学習を行うのかを説明していきたいと思います。今回は線形識別器として取り上げますが、当然基底関数を変える、カーネル法を用いることで非線形への拡張ができますから、その点についても触れていきたいと思い
Text alternatives - a decision tree - 4 Syllables
To help you write better text alternatives for images, our decision tree asks three main questions. It guides you in choosing a short, long or blank text alternative. 1. What role does the image play? Purely decorative? If the image plays a purely decorative role on the page, use a blank text alternative: (alt=""). A screen reader will then ignore it. If you use decorative images regularly, ask yo
Decision Tree in Matlab
The documentation page of the function classregtree is self-explanatory... Lets go over some of the most common parameters of the classification tree model: x: data matrix, rows are instances, cols are predicting attributes y: column vector, class label for each instance categorical: specify which attributes are discrete type (as opposed to continuous) method: whether to produce classification or
Structured support vector machine - Wikipedia
The structured support-vector machine is a machine learning algorithm that generalizes the Support-Vector Machine (SVM) classifier. Whereas the SVM classifier supports binary classification, multiclass classification and regression, the structured SVM allows training of a classifier for general structured output labels. As an example, a sample instance might be a natural language sentence, and the
k-nearest neighbors algorithm - Wikipedia
In statistics, the k-nearest neighbors algorithm (k-NN) is a non-parametric supervised learning method. It was first developed by Evelyn Fix and Joseph Hodges in 1951,[1] and later expanded by Thomas Cover.[2] Most often, it is used for classification, as a k-NN classifier, the output of which is a class membership. An object is classified by a plurality vote of its neighbors, with the object bein

Building Decision Tree Algorithm in Python with scikit learn - Dataaspirant
Decision Tree Algorithm implementation with scikit learn One of the cutest and lovable supervised algorithms is Decision Tree Algorithm. It can be used for both the classification as well as regression purposes also. As in the previous article how the decision tree algorithm works we have given the enough introduction to the working aspects of decision tree algorithm. In this article, we are going

An alt Decision Tree
This decision tree describes how to use the alt attribute of the <img> element in various situations. For some types of images, there are alternative approaches, such as using CSS background images for decorative images or web fonts instead of images of text. Does the image contain text? Yes: … and the text is also present as real text nearby. Use an empty alt attribute. See Decorative Images. … a
Support vector machine in Python using libsvm example of features
I have scraped a lot of ebay titles like this one: Apple iPhone 5 White 16GB Dual-Core and I have manually tagged all of them in this way B M C S NA where B=Brand (Apple) M=Model (iPhone 5) C=Color (White) S=Size (Size) NA=Not Assigned (Dual Core) Now I need to train a SVM classifier using the libsvm library in python to learn the sequence patterns that occur in the ebay titles. I need to extract
