machine learning - ML with fastest classification speed - Cross Validated

Generally, more SVs are used to increase fit to the training set (this is okay, but avoid overfitting). The Bayesian classifier simply requires that you know the distribution of your data. Also, forgot that SVMs are built to only distinguish between 2 classes. To support more classes, multiple SVMs using the one-vs-all approach are merged.

Classification - fairmlbook

What we call classification is also called prediction in other contexts. Likewise, classifiers are often called predictors. For a graduate introduction, see the text by Hardt and Recht.

Support Vector Machine Classifier With Pinball Loss | IEEE Journals ...

Traditionally, the hinge loss is used to construct support vector machine (SVM) classifiers. The hinge loss is related to the shortest distance between sets and the corresponding classifier is hence sensitive to noise and unstable for re-sampling. In contrast, the pinball loss is related to the quantile distance and the result is less sensitive. The pinball loss has been deeply studied and ...

Classification: Thresholding | Machine Learning - Google Developers

A value above that threshold indicates "spam"; a value below indicates "not spam." It is tempting to assume that the classification threshold should always be 0.5, but thresholds are problem-dependent, and are therefore values that you must tune. The following sections take a closer look at metrics you can use to evaluate a classification model ...

Multi-label Text Classification with Machine Learning and Deep Learning ...

Multi-label classifiers deal with such cases. In real life, most of the classification problems need multi-label classification. The main objective of a multi-label classifier is to enable multiple labels for a single entity. However, most of the common algorithms are designed for multi-class classification (not multi-label classification).
