In classification, an algorithm is trained on a dataset of labeled examples, learning to associate input data points with the corresponding category label. Once trained, the model can then categorize new, unseen data points. 1. Input: Continuous (float), Discrete (categorical), etc. 2. Output: Discrete (categorical) 3. Model types: Binary - [[Sigmoid]], polynomial - [[softmax]]
