Function-on-function linear regressionIntegrated squared correlation coefficientIntegrated squared covariancePenalized generalized functional eigenvalue problemSignal compressionWe consider functional linear regression models with a functional response and multiple functional predictors, with the goal of finding the ...
Functional linear regression is a widely used approach to model functional responses with respect to functional inputs. However, classical functional linear regression models can be severely affected by outliers. We therefore introduce a Fisher-consistent robust functional linear regression model that is ...
线性回归(Linear Regression) 首先要明白什么是回归。回归的目的是通过几个已知数据来预测另一个数值型数据的目标值。假设特征和结果满足线性关系,即满足一个计算公式h(x),这个公式的自变量就是已知的数据x,函数值h(x)就是要预测的目标值。这一计算公式称为回归方程,得到这个方程的过程就称为回归。 线性回归就是...

And the nonparametric models is based on data, the form of its regression function is discretionary, so it has a great adaptability. 而非参数回归模型是基于数据本身,其回归函数的形式可以任意,因而有较大适应性。 www.boshuo.net 2. The correlative coefficients of linear regression function for isochro...
In a linear regression model, the vector of regression coefficients is usually estimated by empirical risk minimization. The predictions depend on and so does the empirical risk. We search for a vector that minimizes the empirical risk. TheOrdinary Least Squares (OLS) estimatorof ...
