Can we use logistic regression for multi class classification ?

Question

Accepted Answer

Yes, logistic regression can be used for multi class classification by using techniques like one-vs-rest or softmax.

Logistic regression is typically used for binary classification, but it can be extended to handle multiple classes.
One common approach is to use one-vs-rest (OvR) strategy, where a separate binary logistic regression model is trained for each class.
Another approach is to use softmax regression, which is a generalization of logistic regression to multiple classes.
Logistic regression can also be used in multinomial logistic regression for multi class classification.
Example: Predicting the type of flower species (e.g. iris setosa, versicolor, virginica) based on features like petal length and width.
