正则化技术是一种改善或减小过拟合问题的方法。线性回归过拟合问题: 逻辑回归过拟合问题: 解决过拟合问题: 正则化:加入惩罚因子λ(正则化参数),使得高阶项尽可能小(趋近于0),J(θ)曲线越平滑线性回归的正则化: Logistic回归的正则化: 特征离散化解决非线性特征问题 ...
The present paper considers a bias correction of AIC for selecting variables in the generalized linear model (GLM). The GLM can express a number of statistical models by changing the distribution and the link function, such as the normal linear regression model, the logistic regression model, ...
Sensitivity and specificity are statistical terms but would not apply to a linear regression with the standard model. Logistic regression would include a sensitivity analysis. A more detailed description of your problem is required. @matt23 wrote: Would sensitivity just mean the coefficient for the ...
Regression models describe the relationship between variables by fitting a line to the observed data. Linear regression models use a straight line, while logistic and nonlinear regression models use a curved line. Regression allows you to estimate how a dependent variable changes as the independent va...
Among the different supervised learning tasks, Survival Analysis is intrinsically more complex to distribute compared to classification and regression models. Indeed, optimising Cox-like loss functions requires the knowledge of all individuals’ sorted times, requiring a ranking evaluation (see Eq.(5))....

Our first implementation of the Lasso to conditional logistic regression was based on the correspondence between the conditional likelihood of conditional logistic regression and the partial likelihood of stratified, discrete-time Cox proportional hazards model (where cases are defined as events and controls...
