About scFocus

💗 scFocus is an innovative approach that leverages reinforcement learning algorithms to conduct biologically meaningful analyses. By utilizing branch probabilities, scFocus enhances cell subtype discrimination without requiring prior knowledge of differentiation starting points or cell subtypes.

To identify distinct lineage branches within single-cell data, we employ the Soft Actor-Critic (SAC) reinforcement learning framework, effectively addressing the non-differentiable challenges inherent in data-level problems. Through this methodology, we introduce a paradigm that harnesses reinforcement learning to achieve specific biological objectives in single-cell data analysis.
