Machine Learning is an essential term in the field of Data Science. We all have read and worked with different algorithms and might have also created many models for our projects. Today, I would like to introduce you to a new way of Machine Learning -- Online Machine Learning. What it is? Wait..!! I recently deployed my model over the server. Isn't it Online? Yes, your doubt is absolutely right. You might have deployed your model but it might not be learning online, and a model that can learn and train itself after being deployed is considered Online. So What..!!! My model does it, I have configured it to learn about the new data periodically. Great... that you have deployed such a model and I do hope that it's working fine, but sorry to say that's still not What we call Online. Then What do you call Online Machine Learning?? Enough of going round and round. Get to the point. Yes yes, just a second I will explain everything about it in some time but before that, I wou
