如何辨析机器学习里四个概念：Estimator, Predictor, Classifier, …
网页Estimator 估计量，用来基于观测数据估计未知总体的参数，是样本空间映射到样本估计值的一个函数。 常见的矩法、极大似然估计法计算的就是estimator 。 Predictor 也是一个函数，可以理解为机器学习问题最终训练得到的决策函数. Classifier 是predictor的一种，用于分类问题. learner 这个概念用的比较少，我理解learner就是用于训练predictor的程序，包括模型选择、损失函数、和优化算法。 发布于 2018-03-17 09:45. 我分不清四个概念，读文献要 …

Linear predictor function - Wikipedia
网页In statistics and in machine learning, a linear predictor function is a linear function (linear combination) of a set of coefficients and explanatory variables (independent variables), whose value is used to predict the outcome of a dependent variable. [1] This sort of function usually comes in linear regression, where the coefficients are ...

How to Identify the Most Important Predictor Variables in
网页I’ll start by showing you statistics that don’t answer the question about importance, which may surprise you. Then, I’ll move on to both statistical and non-statistical methods for determining which variables are the most important in regression models.
Selecting the Best Predictors for Linear Regression in R
网页2021年5月23日 · Leaps is a regression subset selection tool that performs an exhaustive search to determine the most influential predictors for our model (Lumley, 2020). The best predictors are selected by evaluating the combination that leads to the best adjusted r² …
How to Find the Best Predictors for ML Algorithms
网页2020年7月16日 · to avoid overfitting and improve model performance, i.e., prediction performance in the case of supervised classification and better cluster detection in the case of clustering, to provide faster and more cost-effective models, and. to gain a deeper insight into the underlying processes that generated the data.”.
Multiple Linear Regression. A complete study — Model …
网页2020年5月13日 · Multiple Linear Regression: It’s a form of linear regression that is used when there are two or more predictors. We will see how multiple input variables together influence the output variable, while also learning how the calculations differ from that of Simple LR model. We will also build a regression model using Python.
