Online Learning

Online learning is a machine learning paradigm where the model continuously learns from a stream of data, updating its parameters incrementally as new data arrives. Unlike batch learning, where the model is trained on a fixed dataset, online learning adapts to changes in data distributions over time without needing to retrain from scratch. This makes it suitable for dynamic environments and real-time applications.

In plain terms

It's like a student who learns one new concept at a time and integrates it immediately into their existing knowledge, rather than waiting for a whole textbook to be finished.

Why it matters

It allows AI systems to adapt in real-time to evolving data, remaining relevant and accurate without costly full retraining cycles.
