For more elaborate and detailed surveys, we refer the readers to [1]. Examples of topic models include Latent Dirichlet Allocation (LDA) [2][3][4], Author-Topic (AT) model [5][6][7], and co-Author-Topic (coAT) model [8], and many others. text/html 2022-06-30T11:32:48+08:00 http://54xushuo.net/wiki/doku.php?id=zh:tools:mlssvr&rev=1656559968&do=diff Multi-output Least-Squares Support Vector Regression Machine (MLS-SVR) Introduction Multi-output regression aims at learning a mapping from a multivariate input feature space to a multivariate output space. Despite its potential usefulness, the standard formulation of the least-squares support vector regression machine (LS-SVR) [1][2] cannot cope with the multi-output case. The usual procedure is to train multiple independent LS-SVR, thus disregarding the underlying (potentially nonlinear) cro… text/html 2022-06-30T11:33:19+08:00 http://54xushuo.net/wiki/doku.php?id=zh:tools:mtlssvm&rev=1656559999&do=diff Multi-Task Least-Squares Support Vector Machines (MTLS-SVM) Introduction Programming Language MATLAB Source Codes <https://github.com/pzczxs/MTLSSVM> Citation Information If you find this toolbox useful, please cite MTLS-SVM as follows: * Shuo Xu, Xin An, Xiaodong Qiao, and Lijun Zhu, 2014. text/html 2022-06-30T11:32:59+08:00 http://54xushuo.net/wiki/doku.php?id=zh:tools:naivebayes&rev=1656559979&do=diff Naive Bayes Introduction The naïve Bayes (NB) classifier is a family of simple probabilistic classifiers based on a common assumption that all features are independent of each other, given the category variable. The different NB classifiers differ mainly by the assumptions they make regarding the distribution of features. The assumptions on distribution of features are called event models of the NB classifier [1]. For discrete features, multinomial or Bernoulli distributions are popular.
