Webb25 dec. 2024 · Incremental learning refers to a family of scalable algorithms that learn to sequentially update models from infinite data streams¹. Whereas in “traditional” machine learning, we’re given a complete dataset consisting of (input, output) pairs, in incremental learning, we don’t have all of the data available when creating the model.
