I'll be at the AI Virtual Cells and Instruments: A New Era in Drug Discovery and Development.

Stop by to chat about generative models and virtual cells! I'll be presenting our work @biohub.org on a scalable latent diffusion model for single-cell gene expression data.

Virtual Cell Perturbation Metrics Reloaded Thoughts on metrics for perturbation prediction models

As more single-cell perturbation data become available, it is crucial to establish a consensus on measures of success for perturbation prediction models.

I reviewed recent literature and collected some thoughts on the current state of affairs.

We are excited because it presents a novel way to learn "latent tokens" of gene expression variation, overcoming many of the limitations of order(less) tokenization and learning schemes. We show its performance in generative and representation learning tasks.

Yesterday, we released a new paper on a novel architecture for single-cell genomics. We call it scLDM to hint at the Latent Diffusion Model paradigm, a generative modeling framework that has been very successful across various domains.

Excited to see a home for MCP servers in bioinformatics emerge! The community needs a central hub for developing MCP servers for key bioinfo tools. At @scverse.bsky.social we're contributing to this effort - can't wait to share what we're building

GitHub - quadbio/cell-annotator: Automatically annotate cell types, consistently across samples. Automatically annotate cell types, consistently across samples. - quadbio/cell-annotator

Happy to share CellAnnotator, a lightweight Python package to query OpenAI models for initial cell type annotations: github.com/quadbio/cell...

Inspired by ideas in www.nature.com/articles/s41... and github.com/VPetukhov/GP..., implemented as an scVerse ecosystem package with docs and tutorials.

A pre-trained SCVI model of our Tahoe-100M cell atlas is now available as a HubModel! It can be used for gene expression visualization, differential expression, or cell clustering. Available at Hugging Face with instructions on how to load it (see thread)
