**TLDR:** A learning approach in which the model is updated incrementally with new examples arriving over time rather than all at once.

<p>Online learning is especially important in environments where data is not static and changes over time. Instead of training once on a fixed dataset, the model is updated incrementally as new examples arrive. Financial streams, user behavior, cybersecurity events, and real-time operational systems often require this setup. The main strength of online learning is adaptability; its main challenge is that uncontrolled updates may reduce system stability. In other words, online learning is not just about speed, but about balancing adaptation with control.</p>
