This paper studies whether lightweight depthwise convolutions can provide local inductive bias to LLMs without materially increasing model size. Macro-level ablation on Qwen3 Transformer blocks finds optimal placement of convolution on projected queries, keys, and values before attention. Micro-level study favors a residual depthwise convolution with kernel size k=3 without extra normalization or activation. Across Qwen3 models and data budgets, this design improves average accuracy on seven downstream benchmarks while adding less than 0.01% parameters. A case study suggests convolution makes repeated token IDs more sensitive to immediate context.

This study uses EEG to examine how word predictability modulates the N400 component across lexical categories.

This paper addresses load imbalance in hierarchical edge-cloud computing by proposing a two-timescale multi-layer deep reinforcement learning framework (2T-MDRL-LA) that jointly optimizes service placement, computational delegation, and power control.

Simulations show up to 20.8% reduction in average end-to-end latency, 13% improvement in resource utilization, and approximately 50% faster convergence than conventional PPO.

E-SpecFormer is an edge-efficient Transformer for end-to-end automatic modulation and covert channel recognition. It introduces LiTAN, a Softmax- and LayerNorm-free attention mechanism that reduces complexity while increasing accuracy. With four scalable variants, the Nano variant achieves 86.5% accuracy on RadioML2018 (SNR>0 dB) and 94.2% on hardware Trojan-based CC datasets, with fewer than 10k parameters and 92 μs per frame on FPGA/CPU co-execution, surpassing state-of-the-art edge models at a fraction of the cost. This establishes E-SpecFormer as an edge-efficient solution for real-time spectrum intelligence on IoT devices.

This paper introduces a validation-gated reliability estimation method that bundles output confidence with whole-sample spectral descriptors (band energy, entropy, peak dominance, period support, phase stability) to estimate trustworthiness without altering backbone predictions. On eight UCR/UEA datasets and eight backbone families, the method improves Corr-AURC from 0.693 to 0.786 and reduces [email protected] to 0.094.

Calibration is usually evaluated in aggregate, but the most dangerous failures are often local: predictions that remain highly confident despite being wrong. This paper introduces FALCON-Discover, a post-hoc, model-agnostic framework to detect concentrated false-confidence regions. Across seven datasets, discrepancy-based ranking outperforms calibration baselines in strong regimes. The best detector varies by dataset: learned discrepancy works best when multiple cues combine, while stability-centered ranking works best when local decisional fragility dominates. Results suggest dangerous overconfidence should be treated as a family-level discovery problem.

Modern LLM query routers often ignore generation latency, focusing only on accuracy and cost. This paper introduces a lightweight latency estimator that simulates autoregressive token batch processing to predict time-to-first-token (TTFT), and integrates it into a router that jointly optimizes latency, accuracy, and cost. Experiments show up to 40% improvement in accuracy-cost utility while maintaining the same latency as standard load-balancing approaches.

This paper proposes angular stabilization of drone motion using distributed feedback control in the form of an integral operator with possibly unbounded memory. The authors introduce a universal approach to study stability of integro-differential equations, reducing them to systems of ordinary differential equations. For linear approximation in angle stabilization, simple exponential kernels lead to finite systems, while more complex kernels can enhance stabilization. New results on exponential stability are obtained and applied to drone stabilization.

Phionyx is a deterministic AI runtime architecture derived from the broader Echoism interaction framework, introducing a governance-first approach that treats LLM outputs as noisy sensor measurements.

Experimental results show an approximately 31% reduction in computational overhead vs. post-hoc filtering and up to 24% improvement in high-value data retention vs. LRU, with deterministic execution verified over 100 runs.

SAAG proposes a cascaded diagnostic framework that decomposes agent-calling evaluation into three interpretable stages: registry conformance, structural completeness, and argument grounding, with iterative self-repair guided by stage-specific signals, improving argument precision and reducing hallucination.

Existing approaches either describe failure mechanisms without transferable risk estimates or produce risk estimates treating failure paths as black boxes.
