Securing Time Integrity in Energy IoT Against Clock Drift and Y2K38 Failures

STGAT (Spatio-Temporal Graph Attention Network), a clock-dynamics-aware anomaly detection solution that jointly models temporal distortion and inter-device consistency in energy IoT systems, is introduced.

Federated Personalization of Early-Exit Networks

X-FED is proposed, a novel Conflict-Aware Cross-Client Federated Exit Distillation framework that jointly addresses both client- and depth-wise conflicts while extending PFL to early-exit networks and introduces a client-decoupled formulation that reduces communication overhead with theoretical soundness.

Audit Me If You Can: Query-Efficient Active Fairness Auditing of Black-Box LLMs

BAFA, the Bounded Active Fairness Auditor is introduced, the Bounded Active Fairness Auditor for query-efficient auditing of black-box LLMs, suggesting that active sampling can reduce resources needed for independent fairness auditing with LLMs, supporting continuous model evaluations.

KV Admission: Learning What to Write for Efficient Long-Context LLM Inference

This paper formalizes KV management as a causal system of three primitives: KV Admission, Selection, and Eviction, and instantiate KV Admission via Write-Gated KV (WG-KV), a lightweight mechanism that learns to predict token utility before cache entry.

Kascade: A Practical Sparse Attention Method for Long-Context LLM Inference

Kascade is a training-free sparse attention method that leverages known observations such as 1) post-softmax attention is intrinsically sparse, and 2) the identity of high-weight keys is stable across nearby layers to achieve high accuracy on long-context LLM inference.

Better World Models Can Lead to Better Post-Training Performance

It is found that explicit world-modeling yields better representations in terms of higher probing accuracy and steerability of the model, and that better representations yield larger gains from GRPO, especially on harder cube states.

ScalePRM: Training Process Reward Models by Scaling Verification Compute Without Ground Truth

ScalePRM, which scales verification compute as an alternative to ground-truth supervision for training process reward models, generates multiple independent verifications of each reasoning step and aggregate their judgments to produce synthetic step-level labels without ground truth.

SpecPV: Improving Self-Speculative Decoding for Long-Context Generation via Partial Verification

To further accelerate speculative decoding in long-context generation, SpecPV is introduced, a self-speculative decoding approach that performs fast verification using partial key-value states (KV) and periodically applies full verification to eliminate accumulated errors.

Uncertainty Makes It Stable: Curiosity-Driven Quantized Mixture-of-Experts

A curiosity-driven quantized Mixture-of-Experts framework that addresses both accuracy and stability through Bayesian epistemic uncertainty-based routing across heterogeneous experts, suitable for safety-sensitive edge deployments where both accuracy and predictability are critical.

Deep Reinforcement Learning for Dynamic Origin-Destination Matrix Estimation in Microscopic Traffic Simulations Considering Credit Assignment

By reframing DODE as a sequential decision-making problem, this approach addresses the credit assignment challenge through a learned policy and provides a novel framework for calibration of microscopic traffic simulations.
