Support vector machine (SVM) is a learning technique based on the structural risk minimization principle, and it is also a class of regression method with a good generalization ability. This paper presents an improved SMO (sequential minimal optimization) algorithm to train the regression SVM, which...
Regression: Continuous output variable (e.g. weight, height, time, etc.) Classification: The output variable has a categorical nature (e.g. male or female, pass or fail, benign or malignant, etc.) We employ supervised learning methods for two key causes: Prediction: To anticipate the value...

Herbrich has proposed a support vector learning algorithm for ordinal regression based on the Linear Utility Model. His algorithm is intrinsically to train a SVM on a new derived training set, whose size increases rapidly when the original training set gets bigger. This property limits its ...
In machine learning, a numerical optimization algorithm is often used to find a set of values for variables—usually called weights—that minimize some measure of error. For example, logistic regression classification uses a math equation where, if there are n predictor variables, there are n+1 ...
A learning algorithm for regression is studied. It is a modified kernel projection machine (Blanchard et al., 2004 [2]) in the form of a least square regul... G Xin,DX Zhou - 《Applied & Computational Harmonic Analysis》 被引量: 26发表: 2012年 Optimal Rates for Spectral Algorithms with...
CartRegressor aims for solving regression problem using tree model. This implementation can handle both continuous and discrete feature. For more details, please refer to统计学习方法—李航. There exists some decision tree implementation in ipynb file,which hasn't been encapsulated as class. ...
The CatBoost algorithm has quite a number ofparameters to tune the featuresin the processing stage. "Boosting" in CatBoost refers to thegradient boosting machine learning. Gradient boosting is a machine learning technique forregression and classificationproblems. ...
