How to go with the flow: flow matching in bioinformatics and computational biology
Bibliographic record
Abstract
Numerous problems in bioinformatics and computational biology can be framed as a task of learning a mapping from one state of a biological system to another relevant state or to explore novel data points across biologically-constrained spaces. However, manually deriving such mappings (e.g., to transform cells in a diseased state back into a healthy state) or extrapolating from existing datasets to create new data (e.g., for molecular design) is often nontrivial and can require extraordinary domain expertise and resources. Fortunately, the field of generative artificial intelligence (AI) has introduced a new training paradigm referred to as (conditional) flow matching, which has emerged as a promising solution to this problem, with broad applicability in computer vision, natural language processing, and the physical and life sciences. Flow matching is a powerful and principled (data-driven) framework for efficiently learning a mapping between arbitrary pairs of high-dimensional data distributions, making it well suited for addressing problems in molecular and cell biology. In this Review, we characterize the theoretical foundations of flow matching and its applications in biomolecular modeling (e.g., for proteins, DNA/RNA, small molecules, and their interactions) and single/multi-cellular modeling (e.g., for cell phenotyping and imaging), each contributing towards the development of an AI-based virtual cell. Lastly, this review highlights open-source flow matching methods and discusses future directions in flow-based generative modeling for bioinformatics and computational biology.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
