In this work, we discuss building performant Multimodal Large Language Models (MLLMs). particular, study the importance of various architecture components and data choices. Through careful comprehensive ablations image encoder, vision language connector, pre-training choices, identified several crucial design lessons. For example, demonstrate that for large-scale multimodal using a mix image-caption, interleaved image-text, text-only is achieving state-of-the-art (SOTA) few-shot results...

While MLLMs perform well on perceptual tasks, they lack precise multimodal alignment, limiting performance. To address this challenge, we propose Vision Dynamic Embedding-Guided Pretraining (VDEP), a hybrid autoregressive training paradigm for MLLMs. Utilizing dynamic embeddings from the MLP following visual encoder, approach supervises image hidden states and integrates tokens into training. Existing primarily focused recovering information textual inputs, often neglecting effective...

Gluten-free (GF) foods are generally costlier than their gluten-containing counterparts. We conducted an anonymous electronic survey to assess food insecurity in households with a child on prescribed GF diet and how this relates adherence during the COVID-19 pandemic. The proportion of who screened positive using Hunger Vital Sign was similar national rates (19%-24%). Approximately 5% families secure reported insecurity. Parent-reported intentional gluten consumption due limited availability...

Lifelong adherence to a gluten-free diet (GFD) is the primary treatment of celiac disease (CeD), gluten-driven enteropathy. Concerns have been raised about increased exposure arsenic from GFD because rice, which naturally bioaccumulates arsenic, commonly used as substitute for gluten-containing grains such wheat. We hypothesize that increases in newly diagnosed children with CeD after they adopt GFD.
