Support Vector Machines (SVM) Algorithm Explained

A support vector machine (SVM) is a supervised machine learning model that uses classification algorithms for two-group classification problems. After giving an SVM model sets of labeled training data for each category, they're able to categorize new text. Compared to newer algorithms like neural networks, they have two main advantages ...

Classifier (linguistics) - Wikipedia

Classifier systems typically involve 20 or more, or even several hundred, classifiers (separate lexemes that co-occur with nouns). Noun class systems (including systems of grammatical gender ) typically comprise a closed set of two to twenty classes, into which all nouns in the language are divided.

Gaussian Mixture Model (GMM) is a probabilistic model for representing normally distributed subpopulations within an overall population. It is usually used for unsupervised learning to learn the subpopulations and the subpopulation assignment automatically. It is also used for supervised learning or classification to learn the boundary of subpopulations. However, the performance of GMM as a ...

Chinese classifier - Wikipedia

The modern Chinese varieties make frequent use of what are called classifiers or measure words.One use of classifiers is when a noun is qualified by a numeral known as a noun phrase.When a phrase such as "one person" or "three books" is translated into Chinese, it is normally necessary to insert an appropriate classifier between the numeral and the noun.

The eigenspace approach [5] was our model for this first attempt. We start by building three separate eigenspaces using 80% of the extracted frames, one for endings, one for bifurcations and one for plain ridges. Each eigenspace consists of 20 eigenimages which are the principal components of the three sets of extracted fingerprint frames.
