CLEAR: Cooperative Latent Flow for Visual Counterfactual Explanations with Accurate Region Preservation

The paper introduces CLEAR, a latent Flow Matching framework designed to generate visual counterfactual explanations (VCEs) that alter a classifier’s prediction while preserving realistic and decision‑irrelevant content. CLEAR addresses two main issues in latent‑space VCEs: opposing update directions between latent generation and classifier guidance, and unintended changes from VAE reconstruction. By decomposing classifier guidance into cooperative and conflicting components and selectively attenuating the conflicting part, CLEAR achieves counterfactual quality comparable to image‑space methods while being 2.5× faster.

FCx: An algorithm for finding Feasible Counterfactual Explanations

FCx is a new algorithm that generates counterfactual explanations while explicitly enforcing feasibility constraints. It uses a modified Variational Autoencoder with a multi‑factor loss to produce realistic, low‑cost counterfactuals that satisfy both hard constraints supplied by users and soft constraints inferred via causal inference. Experiments on four public datasets demonstrate that FCx matches state‑of‑the‑art performance across multiple metrics while guaranteeing feasibility.

Learning Domain Trajectories with Flow Matching for Gradual Domain Adaptation

The paper introduces FlowGDA, a flow‑matching framework for gradual domain adaptation that models adaptation as continuous transport on a statistical manifold. FlowGDA learns time‑dependent velocity fields to generate smooth domain trajectories, avoiding adversarial Min–Max optimization by using a simulation‑free regression objective. The method incorporates source‑anchored transport, semantic consistency loss, and a two‑stage optimization scheme to prevent semantic drift, achieving superior performance over state‑of‑the‑art techniques.

Flow Reasoning Models: Turning Flows Into Efficient Recurrent Reasoners

Flow Reasoning Models (FRMs) are a new framework that turns continuous flow models into efficient recurrent reasoners for structured tasks. By self‑conditioning a flow model on its own past outputs, FRMs iteratively refine solutions, allowing parallel decision making and revision. The authors introduce Fixed‑Point Forcing (FPF) to mitigate exposure bias at deeper recursion, and report near‑perfect solve rates on Sudoku‑Extreme, Zebra, and Maze‑Unique, outperforming existing masked‑diffusion and specialized baselines while using far fewer inference FLOPs.
