• Factuality and Transparency Are All RAG Needs! Self-Explaining Contrastive Evidence Re-ranking \ This extended abstract introduces Self-Explaining Contrastive Evidence Re-Ranking (CER), a novel method that restructures retrieval around factual evidence by fine-tuning embeddings with contrastive learning and generating token-level attr… \ Source • arXiv cs.CL • 18:24
• MMAG: Mixed Memory-Augmented Generation for Large Language Models Applications \ Large Language Models (LLMs) excel at generating coherent text within a single prompt but fall short in sustaining relevance, personalization, and continuity across extended interactions. Human communication, however, relies on multiple fo… \ Source • arXiv cs.CL • 14:06
• MemLoRA: Distilling Expert Adapters for On-Device Memory Systems \ Memory-augmented Large Language Models (LLMs) have demonstrated remarkable consistency during prolonged dialogues by storing relevant memories and incorporating them as context. Such memory-based personalization is also key in on-device se… \ Source • arXiv cs.CL • 13:56
• OsmT: Bridging OpenStreetMap Queries and Natural Language with Open-source Tag-aware Language Models \ Bridging natural language and structured query languages is a long-standing challenge in the database community. While recent advances in language models have shown promise in this direction, existing solutions often rely on large-scale cl… \ Source • arXiv cs.CL • 13:24
• Ground-Truth Subgraphs for Better Training and Evaluation of Knowledge Graph Augmented LLMs \ Retrieval of information from graph-structured knowledge bases represents a promising direction for improving the factuality of LLMs. While various solutions have been proposed, a comparison of methods is difficult due to the lack of chall… \ Source • arXiv cs.CL • 09:34
• ADAPT: Learning Task Mixtures for Budget-Constrained Instruction Tuning \ We propose ADAPT, a meta-learning algorithm that \emph{learns} task sampling proportions under an explicit token budget for multi-task instruction tuning. Instead of fixing task weights by hand, \adapt{} maintains a continuous distribution… \ Source • arXiv cs.CL • 09:17
• David vs. Goliath: Can Small Models Win Big with Agentic AI in Hardware Design? \ Large Language Model(LLM) inference demands massive compute and energy, making domain-specific tasks expensive and unsustainable. As foundation models keep scaling, we ask: Is bigger always better for hardware design? Our work tests this b… \ Source • arXiv cs.LG • 19:37
• Environment-Aware Channel Inference via Cross-Modal Flow: From Multimodal Sensing to Wireless Channels \ Accurate channel state information (CSI) underpins reliable and efficient wireless communication. However, acquiring CSI via pilot estimation incurs substantial overhead, especially in massive multiple-input multiple-output (MIMO) systems … \ Source • arXiv cs.LG • 17:35
