Traditional machine learning relies on offline processing of training data to determine optimal parameters for the model. However, in many real-world applications, data is constantly changing and must be adjusted in real-time; this is where online learning comes into play as it allows the model to continuously update its parameters as new information becomes available.

Online learning provides computers with an interactive way to learn and make predictions about new information as it comes in, without waiting until all the facts are known. This enables computers to develop faster and make accurate predictions in real-time - like students who are constantly discovering new things while making predictions based on what they have already absorbed. Online learning encourages them to keep on learning throughout their lives instead of waiting until they know everything before making predictions.

Let's say you have a toy box filled with numerous toys. Now, imagine wanting to play with one particular toy but can't seem to locate where it went. Start searching through the toy box, picking up pieces of each to see if any are identical - then try guessing which one it might be!
Machine learning works similarly to what a human does when searching for the answer to a question, much like you are searching through toys to find your favorite toy. But instead of toys, computers look at numbers and patterns within data to find answers.
By studying patterns and numbers, the computer can learn to find answers more quickly next time, just as a child remembers where their toy was put when they want to play with it again. That's why we call this "machine learning", because the computer is actually learning just like a child!

Introduction

Online learning is a machine learning method that enables the model to learn incrementally from individual examples and make predictions without waiting until all data has been processed. This approach works best when dealing with large streaming datasets that cannot be stored all at once in memory.

Traditional machine learning relies on offline processing of training data to determine optimal parameters for the model. However, in many real-world applications, data is constantly changing and must be adjusted in real time; this is where online learning comes into play as it allows the model to continuously update its parameters as new information becomes available.
