What is siglip-base-patch16-224?
SigLIP base-patch16-224 is an advanced vision-language model that builds upon CLIP's architecture while introducing a novel sigmoid loss function. Developed by Google Research, this model represents a significant advancement in multimodal learning, specifically designed for image-text understanding tasks.
Implementation Details
The model processes images at 224x224 resolution using a patch-based approach with 16x16 patches. It employs a sophisticated preprocessing pipeline that normalizes images across RGB channels (mean: 0.5, std: 0.5) and handles text with a 64-token limit. Training was conducted on 16 TPU-v4 chips over three days using the WebLI dataset.
