The paper introduces Evidence-Aligned Entity Verification (EAEV), a method for detecting entity-level hallucinations in retrieval-augmented generation (RAG). EAEV aligns generated entities with retrieved evidence across three dimensions and uses counterfactual stability analysis to maintain robust alignments when evidence changes. Experiments on multiple RAG benchmarks show that EAEV consistently outperforms existing hallucination detection methods and generalizes well.

The paper introduces Retrieval-Augmented Decoding (RAD), a decoding-time method that improves the truthfulness of large language models without retraining. RAD uses a small reference set of up to ten annotated examples to build a grounding space of context embeddings and next-token logits, which it retrieves and aggregates during inference to shape the model’s output. Experiments on four open-ended generation benchmarks and four different LLMs show that RAD consistently outperforms strong baselines and generalizes well across tasks.

R-DEIM Net is a 76‑million‑parameter dual‑expert model designed for paraphrase detection that balances accuracy with computational efficiency. It combines an Interaction Expert, which captures token‑level similarity via multi‑scale 2D convolutions and attention, with a Reasoning Expert that generates human‑readable rationales using a Flan‑T5‑small decoder. On the Quora Question Pairs dataset, the model attains 90.07% accuracy and 90.16% F1‑score, matching strong transformer baselines while producing auxiliary rationales.
