· Support vector machine regression data reading, target and predictor features creation, training and testing ranges delimiting. Data: SP 500® index repliing ETF (ticker symbol: SPY) daily adjusted close prices (). Data daily arithmetic returns used for target feature (current day) and predictor feature (previous day).
· Support Vector Regression (SVR) is a supervised learning model that can be used to perform both linear and nonlinear regressions. In the previous lessons, we learned that the goal of applying linear regression is to minimize the error between the prediction and data.
Support vector machine (SVM) analysis is a popular machine learning tool for classifiion and regression, first identified by Vladimir Vapnik and his colleagues in 1992 . SVM regression is considered a nonparametric technique because it relies on kernel functions. Statistics and Machine Learning Toolbox™ implements linear epsiloninsensitive SVM (εSVM) regression, which is also .
RSM is employed to determine the optimal values of SVR hyperparameters and is compared to the genetic algorithm (GA). The proposed PCSVR model is confirmed with the actual plant data of Kori Nuclear Power Plant Unit 3 and is compared with the AutoAssociative support vector regression (AASVR) and the autoassociative neural network (AANN) model.
One of the most prevailing and exciting supervised learning models with associated learning algorithms that analyse data and recognise patterns is Support Vector Machines (SVMs). It is used for solving both regression and classifiion problems. However, it is mostly used in solving classifiion problems.
· Linear regression finds out a linear relationship between the input and output. For example: "a" as input and "b" as output, a linear function would be b = k*a+ c. What Are Support Vectors. Support Vectors are the data points that help us to optimize the hyperplane. These vectors lie closest to the hyperplane and are most difficult to classify.

· The Support vector regression (SVR) was used to investigate quantitative structure–activity relationships (QSAR) of 75 phenolic compounds with Troloxequivalent antioxidant capacity (TEAC).
· Support Vector Regression (SVR) works on similar principles as Support Vector Machine (SVM) classifiion. One can say that SVR is the adapted form of SVM when the dependent variable is numerical rather than egorical. A major benefit of using SVR is that it is a nonparametric technique.
Support vector regression based Stransform for prediction of single and multiple power quality disturbances. This paper presents a novel approach using Support Vector Regression (SVR) based Stransform to predict the classes of single and multiple power quality disturbances in a threephase industrial power system.

ically used to describe classiﬁion with support vector methods and support vector regression is used to describe regression with support vector methods. In this report the term SVM will refer to both classiﬁion and regression methods, and the terms Support Vector Classiﬁion (SVC) and Support Vector Regression (SVR) will be used
· Support vector regression is a type of support vector machine SVR is tube like structure. We do not care about the points in the tube whereas we care about the points outside the tube as it determines the tube position.
· Support Vector Machine is one of the regression methods. Support Vector Machine maintains all the core features that describe the characteristics of the algorithm. The Support Vector Machine (SVM) for classifiion is mostly similar to the Support Vector Regression (SVR). However, only a little difference exists among both of these two methods.
