SVMs vs. logistic regression Logistic regression is a linear classifier and often struggles with complex data sets that are not linearly separable. SVMs can effectively classify nonlinear data, especially with the kernel trick. SVMs tend to perform better in high-dimensional spaces. Logistic regression...
Anyway, going back to the logistic sigmoid. One of the nice properties of logistic regression is that the logistic cost function (or max-entropy) is convex, and thus we are guaranteed to find the global cost minimum. But, once we stack logistic activation functions in a multi-layer neural ...
For instance, a BMI of 30 indicates obesity. That’s often true for the general public but definitely not for strength athletes such as NFL linebackers. Logistic regression: Best used for binary outcomes, logistic regression is like linear regression but with special considerations at the ...
Logistic regression: Best used for binary outcomes, logistic regression is like linear regression but with special considerations at the boundaries of possible data ranges. An example of logistic regression includes pass/fail analysis on the likelihood of converting a potential customer into a paying on...
Logistic regression is a part of a larger family of generalized linear models (GLMs). Just like evaluating the performance of a classifier, it's equally important to know why the model classified an observation in a particular way. In other words, we need the classifier's decision to be int...

Regression (linear and logistic)is one of the most popular method in statistics. Regression analysis estimates relationships among variables. Intended for continuous data that can be assumed to follow a normal distribution, it finds key patterns in large data sets and is often used to determine how...
