PhysGuard uses Fisher-guided gradient projection to adapt neural PDE surrogates to real data while preserving physics-critical parameters, cutting low-frequency error by up to 32% under severe domain shift.
BETA uses a local steering model and prediction harmonization to stabilize black-box test-time adaptation with zero extra API queries and large accuracy gains.
Using input-to-state stability, zeroth-order optimization achieves first-order convergence rates without extra dimension dependence when perturbations are small.
RAIL introduces a CHC-based benchmark evaluating LALMs across five auditory cognitive abilities, revealing highly uneven performance among 26 state-of-the-art models.
VEX-Bench benchmarks verification complexity of LLM-generated misinformation, showing high-VEX false content costs 3-169x less to create than to verify and risks misallocating scarce screening resources.
SVoT uses reinforcement learning to generate verifiable intermediate states and visualizations for multi-hop spatial reasoning, achieving up to 65% out-of-distribution accuracy gains.
CELEUS uses E-processes with uncertainty-guided sampling and surrogate approximations to provide anytime-valid confidence intervals for LLM evaluation, cutting required samples by 54-62%.
Environment-induced diffusion shifts identify latent SDE coordinates and drift-Jacobian causal graphs up to permutation and scaling without sparsity assumptions.
Data laundering transforms proprietary data to hide LLM training traces, and Synthesis Data Reversion restores detection by synthesizing likely transformed queries via goal-detail abstraction.
FiLoRA is an instruction-conditioned LoRA framework that modulates multimodal model reliance on internal feature pathways via gated low-rank modules, enabling controllable amplification or suppression of feature groups without changing task semantics.
Mechanistic analysis reveals a Commit-Abstain Circuit where early commitment signals overpower later abstention corrections, causing hallucinations; training on its activations improves abstention accuracy by 12.2 points.
TrajWiki represents memory as source-grounded evolution trajectories with claim-level updates and a wiki layer to improve long-horizon dialogue performance and interpretability.
A framework generates provably robust verification instances with known ground-truth labels and exposes numeric errors and bugs in state-of-the-art neural network verifiers.
USAD improves adversarial detection via variance and perturbation covariance discrepancy statistics that capture global and local uncertainty patterns in adversarial examples.
