This innovative approach involved combining the insights of text (titles/descriptions) and images. To achieve this, they converted both text and image data into vectors and then find similar products by for example using a Faiss index and other.

Introduction I was once told that a good programmer is a lazy programmer. A good programmer avoids typing tedious code, where the code could basically write itself. Self-writing code – wouldn’t that be great? Unfortunately, we’re not quite there yet.

Introduction MapStruct is a framework that alleviates us, programmers, from the unexciting task of writing code to copy one object model to another, field by field. This blog elaborates on how to write MapStruct mappers for object hierarchies. If,...
