🔬Causal Models Need Causal Data - Xaira’s X-Cell model for Drug Discovery (Bo Wang & Ci Chu, Chief Discovery Officer & Chief AI Scientist)
Xaira Therapeutics' X-Cell model for drug discovery relies on a large dataset, X-Atlas, which contains information-rich data on gene expression in human cells, enabling the model to predict changes to gene expression and understand the relationships between cell types and states. This approach contrasts with traditional models that rely on smaller, less informative datasets. The X-Cell model has achieved significant improvements over previous models, demonstrating the importance of data quality in AI-driven drug development. AI summary
