PassiveQA: A Three-Action Framework for Epistemically Calibrated Question Answering via Supervised Finetuning

Researchers propose PassiveQA, a new AI framework that teaches language models to recognize when they don't have enough information to answer questions, choosing to ask for clarification or abstain rather than hallucinate responses. The three-action system (Answer, Ask, Abstain) uses supervised fine-tuning to align model behavior with information sufficiency, showing significant improvements in reducing hallucinations.

Opal: Private Memory for Personal AI

Researchers present Opal, a private memory system for personal AI that uses trusted hardware enclaves and oblivious RAM to protect user data privacy while maintaining query accuracy. The system achieves 13 percentage point improvement in retrieval accuracy over semantic search and 29x higher throughput with 15x lower costs than secure baselines.

Type-Aware Retrieval-Augmented Generation with Dependency Closure for Solver-Executable Industrial Optimization Modeling

Researchers developed a type-aware retrieval-augmented generation (RAG) method that translates natural language requirements into solver-executable optimization code for industrial applications. The method uses a typed knowledge base and dependency closure to ensure code executability, successfully validated on battery production optimization and job scheduling tasks where conventional RAG approaches failed.

Context-Aware Generative AI for Automated Telecom Test Script Generation

Researchers present a context-aware generative AI framework for automated telecom test script generation that continuously adapts to live system changes rather than relying on static test suites. The system uses a knowledge graph, delta-detection engine, and RAG-enhanced AI agent to automatically create, update, or retire test cases as code, configurations, and KPIs evolve, significantly reducing manual testing effort.

The Structural Attention Tax: How Retrieval Format Hijacks In-Context Learning Independent of Content

Researchers identify a 'structural attention tax' where knowledge graph formats capture 2-3x more model attention than semantically equivalent natural language, degrading in-context learning performance by up to 42% regardless of content relevance. The study formalizes attention decomposition into semantic and structural components, revealing that retrieval format can independently distort LLM outputs independent of knowledge quality.

Didact: A Cross-Domain Capability Discovery System for Defence

Didact is a prototype system that integrates Australian defence reports, policy documents, and research publications into a unified knowledge graph to help policymakers discover defence capabilities faster. The system uses retrieval-augmented generation (RAG) and natural language conversations to surface fragmented information across heterogeneous sources, with an interactive Evidence Rail for visualizing source relationships.

LongTraceRL: Learning Long-Context Reasoning from Search Agent Trajectories with Rubric Rewards

Researchers introduce LongTraceRL, a reinforcement learning method that improves large language models' ability to reason over lengthy documents by using search agent trajectories and entity-level reward signals. The approach generates challenging training contexts with high-confusability distractors and applies rubric rewards that supervise intermediate reasoning steps, demonstrating consistent improvements across multiple LLM sizes and benchmarks.

KARMA-MV: A Benchmark for Causal Question Answering on Music Videos

Researchers introduce KARMA-MV, a large-scale dataset of 37,737 multiple-choice questions derived from 2,682 YouTube music videos, designed to benchmark AI models' ability to reason about causal relationships between visual dynamics and musical structure. The dataset leverages LLM-based generation for scalability and proposes a causal knowledge graph approach to improve vision-language model performance on cross-modal audio-visual reasoning tasks.

MMCOMET: A Large-Scale Multimodal Commonsense Knowledge Graph for Contextual Reasoning

Researchers have released MMCOMET, the first large-scale multimodal commonsense knowledge graph that combines visual and textual information with over 900K multimodal triples. The system extends existing knowledge graphs to support complex AI reasoning tasks like image captioning and visual storytelling, demonstrating improved contextual understanding compared to text-only approaches.
