Онлайн-машинное обучение updates a model incrementally as data arrives in sequence. Оно useful when data streams continuously, datasets are too large for batch training, or the model must adapt to changing patterns.
A method of machine learning in which data becomes available in a sequential order and is used to update the best predictor for future data at each step, as opposed to batch learning techniques which generate the best predictor by learning on the entire training data set at once. Online learning is a common technique used in areas of machine learning where it is computationally infeasible to train over the entire dataset, requiring the need of out-of-core algorithms. It is also used in situations where it is necessary for the algorithm to dynamically adapt to new patterns in the data, or when
