language models, ... |
2502.07617 | Scaling Pre-training to One Hundred Billion Data for Vision Language
Models | cs.CV | We provide an empirical investigation of the potential of pre-training
vision-language models on an unprecedented scale: 100 billion examples. We find
that model performance tends to saturate at this scale on many common
Western-centric classification and retrieval benchmarks, such as COCO Captions.
Nevertheless, tas... |
