Xaira Therapeutics发布X-Cell模型,用于AI驱动的药物发现

Xaira Therapeutics,由首席发现官Ci Chu和首席AI科学家Bo Wang领导,开发了X-Cell模型用于药物发现。该模型在X-Atlas上进行训练,X-Atlas是一个通过CRISPR实验生成的新型数据集,可以并行测试基因表达变化。与之前专注于RNA表达的模型不同,X-Cell旨在预测改变特定基因的影响,这是开发靶向药物或基因疗法的关键步骤。该团队已将X-Cell的模型从自回归模型转向扩散模型,并证明了其泛化到真实细胞实验的能力,优于现有的线性基线模型。 AI

影响 这一发展可以通过实现对基因表达变化更精确的预测,来加速AI驱动的药物发现。

排序理由 该集群描述了一个用于药物发现的新模型和数据集,属于研究范畴。
