Linear models are the simplest parametric methods and always deserve the right attention, because many problems, even intrinsically non-linear ones, can be easily solved with these models. As discussed previously, a regression is a prediction where the target is continuous and it has several ...
不同的机器学习任务有着不同的评价指标,同时同一种机器学习任务也有着不同的评价指标,每个指标的着重点不一样。如分类(classification)、回归(regression)、排序(ranking)、聚类(clustering)、热门主题模型(topic modeling)、推荐(recommendation)等。并且很多指标可以对多种不同的机器学习模型进行评价,如精确率-召回率(...
In this work, we study the use of logistic regression in manufacturing failures detection. As a data set for the analysis, we used the data from Kaggle competition Bosch Production Line Performance. We considered the use of machine learning, linear and Bayesian models. For machine learning approa...
In this tutorial, you will discover how to develop deep learning models for multi-output regression. After completing this tutorial, you will know: Multi-output regression is a predictive modeling task that involves two or more numerical output variables. Neural network models can be configure...
This becomes relevant if you look at regularization methods that change the learning algorithm to reduce the complexity of regression models by putting pressure on the absolute size of the coefficients, driving some to zero. Now that we understand the representation used for a linear regression ...
