UnverifiedAblation experiments show that all three components of D²-OPD—the hard KL constraint, adaptive direction combination, and forward KL optimization—each contribute positively to final performance.72% similarUnverifiedDPT achieves state-of-the-art results on multiple reasoning benchmarks, indicating that the gains brought by path diversity are transferable across tasks.67% similarUnverifiedWhen d=1, the orthogonal constraint degenerates to spherical optimization, i.e., the direction of each row lies on its own unit sphere, which by itself already outperforms the tuned Muon optimizer.66% similarUnverifiedGaussian splatting DFT uses the Löwdin orthogonalization technique to project the optimization step back onto the feasible manifold to satisfy the orbital orthonormality constraint.66% similarUnverifiedAdaptive optimizers such as Adam and RMSProp have partially mitigated the stiffness problem in a low-cost manner, approximating a similar effect through per-coordinate adaptive step sizes, which is simpler in engineering practice.63% similar
