Question
What is a disadvantage of one-vs-all classification?
Solution
One disadvantage of one-vs-all classification is that it can be computationally expensive. This is because it requires training multiple binary classifiers, one for each class, which can be time-consuming and resource-intensive. Additionally, as the number of classes increases, the training and prediction time also increases significantly.
