Witryna15 lip 2024 · Logistic regression is a Machine Learning classification algorithm that is used to predict the probability of certain classes based on some dependent variables. In short, the logistic regression model computes a sum of the input features (in most cases, there is a bias term), and calculates the logistic of the result. Witryna10 sty 2024 · We constructed a logistic regression-based ML algorithm to predict “severe” COVID-19, defined as patients requiring intensive care unit (ICU) admission, invasive mechanical ventilation, or died in or out-of-hospital.

WitrynaLogistic regression is an algorithm that learns a model for binary classification. A nice side-effect is that it gives us the probability that a sample belongs to class 1 (or vice versa: class 0). Our objective function is to minimize the so-called logistic function Φ (a certain kind of sigmoid function); it looks like this: ...
