title: How to add a new class to an existing classifier in deep learning?
body: <p>I trained a deep learning model to classify the given images into three classes. Now I want to add one more class to my model. I tried to check out &quot;Online learning&quot;, but it seems to train on new data for existing classes. Do I need to train my whole model again on all four classes or is there any way I can just train my model on new class?</p>
