Arc recently unveiled the Virtual Cell Challenge - we explore the challenge from a non-biologist's perspective in the hope of encouraging participation from a range of disciplines. Published: ⏱ 14 Min Read Arc Institute recently unveiled the Virtual Cell Challenge. Participants are required to train a model capable of predicting the effect of silencing a gene in a (partially) unseen cell type, a task they term context generalization. For ML engineers with little to no biology background, the jargon and required context can seem quite daunting. To encourage participation, we recapitulate the challenge in a form better suited to engineers from other disciplines. Goal Train a model to predict the effect on a cell of silencing a gene using CRISPR. Doing things in the world of atoms is expensive, laborious and error prone. What if we could test thousands of drug candidates without ever touching a petri dish? This is the goal of the virtual cell challenge — a model (most likely a neural netw
