PhylaFlow model learns phylogenetic tree transport in BHV space

By PulseAugur Editorial · [1 sources] ·

Researchers have developed PhylaFlow, a novel hybrid flow-matching model designed for phylogenetic inference. This model operates within the Billera-Holmes-Vogtmann (BHV) tree space, which geometrically represents phylogenetic trees. PhylaFlow learns to transport trees from random starting points to regions of posterior probability, coupling continuous branch-length adjustments with discrete topological changes. Evaluations on several phylogenetic benchmarks show that PhylaFlow significantly improves the efficiency of Bayesian refinement and topology recovery compared to existing methods, particularly in challenging cases.

    PhylaFlow: Hybrid Flow Matching in Billera-Holmes-Vogtmann Tree Space for Phylogenetic Inference

    arXiv:2605.21859v1 Announce Type: cross Abstract: Phylogenetic trees are hybrid objects: branch lengths vary continuously, while topologies change discretely through edge contractions and expansions. Billera-Holmes-Vogtmann (BHV) tree space provides a canonical geometry for this …
