Beit V2 Masked Image Modeling With Vector Quantized Visual Tokenizers

Beit V2 Masked Image Modeling With Vector Quantized Visual Tokenizers In this work, we propose to use a semantic rich visual tokenizer as the reconstruction target for masked prediction, providing a systematic way to promote mim from pixel level to semantic level. This paper proposes a new masked image modeling method (beit v2). a new vector quantized knowledge distillation helps the beit v2 explore the high level semantics.

Beit V2 Masked Image Modeling With Vector Quantized Visual Tokenizers A self supervised vision representation model beit, which stands for bidirectional encoder representation from image transformers, is introduced, and results on image classification and semantic segmentation show that the model achieves competitive results with previous pre training methods. For help or issues using beit v2 models, please submit a github issue. for other communications, please contact li dong (lidong1@microsoft ), furu wei (fuwei@microsoft ). In this work, we study masked image modeling (mim) and indicate the advantages and challenges of using a semantically meaningful visual tokenizer. we present a self supervised framework ibot that can perform masked prediction with an online tokenizer. Specifically, we propose vector quantized knowledge distillation to train the tokenizer, which discretizes a continuous semantic space to compact codes. we then pretrain vision transformers by predicting the original visual tokens for the masked image patches.

Specifically, we propose vector quantized knowledge distillation to train the tokenizer, which discretizes a continuous semantic space to compact codes. we then pretrain vision transformers by predicting the original visual tokens for the masked image patches. Compared with masked distillation methods, like mvp, beit v2 also shows superiority. furthermore, with a longer pretraining schedule, beit v2 achieves 85.5% top 1 accuracy, developing a new state of the art on imagenet 1k among self supervised methods. Beit v2 employs vector quantized knowledge distillation and patch aggregation to shift masked image modeling from pixel recovery to semantic token prediction, enhancing vision representation. Specifically, we introduce vector quantized knowledge distillation to train the tokenizer, which discretizes a continuous semantic space to compact codes. we then pretrain vision transformers by predicting the original visual tokens for the masked image patches.
