Expected Value vs. Distributional Flow Matching
Experimental results demonstrate that standard flow matching (floq) targeting expected values outperforms distributional variants, even though distributional RL often leads to higher variance estimates more aligned with the return distribution.

Distributional RL Necessary?
Flow matching's success is not attributed to distributional RL; expected-value backups consistently outperform distributional variants.

Test-Time Recovery (TTR) Enabled
Flow-matching enables robust value prediction through iterative computation that dampens errors in early estimates. This mechanism is absent in monolithic critics.
Case Study: Robustness to Noisy TD Targets
Flow-matching critics demonstrate significantly higher robustness to noise in TD targets compared to monolithic critics. Their performance degradation is much more graceful, allowing later integration steps to attenuate the effect of noisy supervision.
Enterprise Impact: Enterprise AI systems often face noisy or uncertain data streams. Flow-matching's inherent resilience ensures more stable and reliable value predictions even in suboptimal data environments, reducing the need for extensive data cleaning or complex regularization.

Plastic Feature Representation
Flow-matching critics learn more plastic features, allowing adaptation to non-stationary TD targets by reweighting existing features rather than overwriting them, unlike monolithic critics.
Case Study: The Crucial Role of Velocity Supervision
Directly supervising the velocity field at multiple interpolant values is critical. When critics are trained to predict final TD targets instead of velocities, flow matching collapses to monolithic behavior, losing its benefits in TTR and plasticity. This highlights the importance of the dense velocity supervision mechanism.
Enterprise Impact: For enterprises, this means that the specific training methodology—supervising velocities, not just final values—is key to unlocking flow matching's advanced capabilities. Implementing flow-matching requires adherence to these principles to achieve robust and adaptive AI systems.
