Support vector machines: The linearly separable .

Again, the points closest to the separating hyperplane are support vectors. The geometric margin of the classifier is the maximum width of the band that can be drawn separating the support vectors of the two classes. That is, it is twice the minimum value over data points for given in Equation 168, or, equivalently, the maximal width of one of the fat separators shown in Figure 15.2.

Classifier Model - an overview | ScienceDirect .

Two of the most popular methods for semi-supervised learning are Co-Training (Blum and Mitchell, 1998) and Semi-Supervised Support Vector Machines (S3VM) (Sindhwani and Keerthi, 2006). Co-Training assumes the presence of multiple views for each feature and uses the confident samples in one view to update the other. However, in applications such as image classification, one often has just a ...

What is the difference between a classifier and a .

Classifier: A classifier is a special case of a hypothesis (nowadays, often learned by a machine learning algorithm). A classifier is a hypothesis or discrete-valued function that is used to assign (categorical) class labels to particular data points. In the email classification example, this classifier could be a hypothesis for labeling emails as spam or non-spam. However, a hypothesis must ...

A popular class of procedures for solving classification tasks are based on linear models. What this means is that they aim at dividing the feature space into a collection of regions labeled according to the values the target can take, where the decision boundaries between those regions are linear: they are lines in 2D, planes in 3D, and hyperplanes with more features.

Which machine learning classifier to choose, in .

How much classification speed do you need? SVM's are fast when it comes to classifying since they only need to determine which side of the "line" your data is on. Decision trees can be slow especially when they're complex (e.g. lots of branches). Complexity. Neural nets and SVMs can handle complex non-linear classification.
