📍 Simple and effective embedding model for single-cell biology built from ChatGPT Chen and Zou introduced GenePT, a simple yet effective embedding model that leverages natural language models such as GPT-3.5 to represent genes and cells by utilizing their text summaries and ranked expression values, respectively. Key points 📌Gene embeddings from text descriptions of individual genes 📌Single-cell embeddings by averaging the gene embeddings weighted by each gene’s expression level 📌A sentence embedding for each cell by using only the gene names ordered by their expression level 📌Comparable or better performance than models pretrained from gene-expression profiles of millions of cells. ➡️ More details: https://lnkd.in/e8C_96Hm #StanfordUniversity #spatialomics #spatialbiology #singlecellanalysis #singlecell
