UPDATE (10/03/23): We have updated the model! We found that laion/CLIP-ViT-B-32-laion2B-s34B-b79K checkpoint (thanks Bin!) worked better than original OpenAI CLIP on Fashion. We thus fine-tune a newer (and better!) version of FashionCLIP (henceforth FashionCLIP 2.0), while keeping the architecture the same. We postulate that the perofrmance gains afforded by laion/CLIP-ViT-B-32-laion2B-s34B-b79K are due to the increased training data (5x OpenAI CLIP data). Our thesis, however, remains the same -- fine-tuning laion/CLIP on our fashion dataset improved zero-shot perofrmance across our benchmarks. See the below table comparing weighted macro F1 score across models. FashionCLIP is a CLIP-based…
