How to Solve Product Classification Challenge for Marketplaces in the Wild

In the pursuit of improved user experience, marketplaces are trying to solve open issues using modern approaches. Today, it seems that AI can easily solve a lot of narrow problems but when it faces real-world questions, it turns out that those questions are much deeper than they seem at first glance. Since we are following current industry dynamics in AI, we have started with image classification. We’ll tell you about our experience with real-world problems associated with this task. How we went from a flat-model to one that is ‘super-complex’ as well as what was successful and what wasn’t.
