Super excited to share my first work as a PhD student!! We propose a new way to generate single-cell data as text using LLMs!

Cell2Sentence: Teaching Large Language Models the Language of Biology

Large language models like GPT have shown impressive performance on natural language tasks. Here, we present a novel method to directly adapt these pretrained models to a biological context, specif...

Some exciting updates for Cell2Sentence!! Turns out fine-tuning language models on sequences of gene names works pretty well. DM me if you'd like to discuss the work/have some H100s and are interested in helping out!

I would guess SORA was trained at least partially with NeRF data at some point. Based almost entirely off the way that the trees look in this video, which screams NeRF artifacts to me.
