Etsy has developed applications like visual search and visually similar recommendations, powered by machine learning models that encode images as vector representations. EfficientNet models and EfficientFormer-l3 are used for visual representation learning. Fine-tuning and multitask learning are employed to further optimize performance. Evaluation of visual representations is done through nearest neighbor retrieval tasks and generative AI. Efficient inference and downstream tasks are also discussed, highlighting the positive impact of efficient visual representations across various applications at Etsy.
