WebMar 21, 2024 · Support Vector Machine is a technique of Machine Learning that tries to find a hyperplane that best separates data classes. It can be applied in both binary and multi-class classification tasks. WebMulticlass-multioutput classification (also known as multitask classification) is a classification task which labels each sample with a set of non-binary properties. Both the number of properties and the number of classes per property is greater than 2. A single estimator thus handles several joint classification tasks.
