This work benchmarks both reconstruction quality, codebook collapse and representational capacity of VQ-VAEs across a variety of settings, surpassing state of the art in the reconstruction task and providing a stepping stone for further development of medical multimodal auto-regressive techniques.
Abstract
Medical diagnosis often benefits from the side-by-side analysis of different sources of information, motivating also the development of multimodal approaches in AI-based applications for healthcare. A current technique for vision-language multimodality is a two-step process of (1) image tokenization through vector quantization followed by (2) auto-regressive modeling. In this work, we explore the image tokenization process for datasets in the medical domain, which are characterized by smaller scale and narrower semantic coverage than natural image datasets. We benchmark both reconstruction quality, codebook collapse and representational capacity of VQ-VAEs across a variety of settings, surpassing state of the art in the reconstruction task and providing a stepping stone for further development of medical multimodal auto-regressive techniques.
The results are packaged in the Greenfield Startup Model (GSM), which explains the priority of startups to release the product as quickly as possible, and the need to shorten time-to-market, by speeding up the development through low-precision engineering activities.
