机器学习基石11：线性模型分类（Linear Models for Classification）

Nettet20. mai 2024 · A popular class of procedures for solving classification tasks are based on linear models. What this means is that they aim at dividing the feature space into a collection of regions labeled according to the values the target can take, where the decision boundaries between those regions are linear: they are lines in 2D, planes in … Nettet29.3 Classification as probability estimation problem. This observation motivates how we will address the classification problem in general. Instead of modeling classes 0 or 1 directly, we will model the conditional class probability \(p(Y=1 X=x)\), and classify based on this probability.

NettetA solution for classification is logistic regression. Instead of fitting a straight line or hyperplane, the logistic regression model uses the logistic function to squeeze the output of a linear equation between 0 and 1. The logistic function is defined as: logistic(η) = 1 1 +exp(−η) logistic ( η) = 1 1 + e x p ( − η) And it looks like ... smart band lockingNettet18. mar. 2015 · 3 Answers. In general the naive Bayes classifier is not linear, but if the likelihood factors p ( x i ∣ c) are from exponential families, the naive Bayes classifier corresponds to a linear classifier in a particular feature space.
