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 … WebbSimilarly, Kabaghe and Qin (2024) did not use advanced neural network architectures and embedding techniques and used a multinomial naive bayes approach to classify tweets based on their attitude toward climate change into three classes: −1 (negative belief), 0 (neutral belief), and 1 (positive belief).

The Gaussian Naive Bayes Classifier is useful to obtain fast, preliminary results, upon data which may come in a stream, and that cannot be processed all at once in memory. Its accuracy is often below that of plain logistic regression, but this weakness may be compensated by its space and time advantages, when applicable.
