Webb11 apr. 2024 · What is the One-vs-One (OVO) classifier? A logistic regression classifier is a binary classifier, by default. It can solve a classification problem if the target categorical variable can take two different values. But, we can use logistic regression to solve a multiclass classification problem also. We can use a One-vs-One (OVO) or One-vs-Rest …
