A likelihood-free neural network estimates phylogenetic tree posteriors via sequence pair encodings and subtree merges, outperforming likelihood-based methods especially for intractable evolutionary models.
Annealed Langevin dynamics replaces biased reverse-SDE sampling for compositional SBI scores with controllable bridging densities, yielding explicit hyperparameter rules; Linhart et al.'s formulation allows larger steps and fewer iterations than Geffner et al.'s in Gaussian settings and generalizes
