Efficient Pre-Training of LLMs through Truncated SVD Representations

The TSVD (Truncated Singular Value Decomposition) framework which efficiently maintains orthonormality through QR decomposition and caching is presented, and a spectral energy heuristic is introduced to select the rank of the resulting low-rank weight matrices.

NeuroRule: Making Black-Box Neural Networks Explainable through Rule-set Evolution

High-capacity neural network models have achieved state-of-the-art performance across diverse classification tasks, yet they frequently operate as black-box models, lacking the transparency necessary for critical decision-making. Such opacity creates a persistent trade-off between performance and explainability. This p...

Legislating World-Model-Based Planning with Legal Reasoning

A legal planning stack that employs Defeasible Deontic Logic (DDL) to constrain a motion planner and leverages learned world models to plan and to provide legal context, enabling ex ante governance that intervenes before an illegal action is executed.

Beyond the Best Guess: Improving LLM Solution Coverage with Evolution Strategies

Evolution Strategies (ES), a population-based, gradient-free post-training method that optimizes directly in weight space through random perturbations, achieves consistently higher pass@k than RL and produces a broader output distribution with greater solution coverage.

Semantic Uncertainty-Guided Orchestration in Hierarchical Multi-Agent Systems

A semantic-uncertainty-guided orchestration approach, HASSUM is introduced as a general framework for uncertainty-aware coordination in multi-agent systems and suggests that semantic uncertainty is a practical and general-purpose signal for improving robustness and trustworthiness in agentic AI systems.
