BlazeVGGT: 13x Faster VGGT at 2,000 Frames via Camera Token without Training

Feed-forward visual geometry models, exemplified by VGGT, have demonstrated strong multi-view reconstruction capabilities through dense global attention. However, the resulting all-to-all cross-view computation scales quadratically with the number of input views, making long-sequence inference particularly expensive du...

Preference-based opponent shaping in differentiable games

A novel Preference-based Opponent Shaping (PBOS) method to enhance the strategy learning process by shaping agents’ preferences towards cooperation by incorporating the preference parameter into the agent’s loss function, thus allowing the agent to directly consider the opponent’s loss function when updating the strate...

A Gauss–Seidel Type Inertial Proximal Stochastic Alternating Direction Method of Multipliers for Nonconvex Finite Sum Optimization

This paper establishes that every bounded sequence generated by Gi-PSADMM with the variance-reduced stochastic gradient estimator converges globally to a critical point in expectation and derives the convergence rate of Gi-PSADMM that depends on the KL exponent.
