Learning-Based Heuristic Dynamic Path Planning Using a Hop- Aware Graph Neural Network and ConvGRU

This paper proposes a learning-based heuristic for dynamic path planning that integrates a hop-aware graph neural network (HopGNN) with a convolutional gated recurrent unit (ConvGRU) to effectively capture multi-scale spatial topologies and temporal environmental changes, demonstrating superior success rates and search efficiency over existing methods like GCN-A*, GAT-A*, and D* Lite in simulated grid environments.

A Multi-Model, Multi-Domain Benchmark of Large Language Model Agreement with Humans and with Each Other in Sentiment Classification

This paper presents a multi-domain benchmark evaluating five large language models, a rule-based lexicon, and a supervised transformer against human annotations, revealing that while top-tier models like Claude Opus 4.7 and GPT-5.5 achieve strong alignment with humans, significant disagreement persists across models and with human labels—particularly on informal text—demonstrating that model selection materially impacts sentiment classification outcomes.

AST-Level Semantic Watermarking Framework for AI-Generated Code: Robust Provenance Attribution via Structural Invariants

This paper proposes a novel, model-agnostic AST-level watermarking framework that embeds cryptographically verifiable signatures into the syntactic topology of AI-generated code through semantics-preserving structural mutations, achieving robust provenance attribution and significantly outperforming existing text-level methods against common code transformations like formatting, renaming, and dead-code injection.

SHAP and LIME Explainability in Financial Machine Learning: A Systematic Review of Methods, Evaluation Gaps, and Barriers to Deployment

This systematic review of 297 studies reveals that while SHAP and LIME are widely adopted for explainability in financial machine learning—particularly for credit modeling—they suffer from a critical lack of formal evaluation, with only 9.1% of papers assessing explanation quality, highlighting an urgent need for stronger validation and deployment standards to ensure regulatory compliance and trust.
