Toward Standardized Evaluation of Metamorphic Relations: A Structured Rubric and Human-LLM Comparison

Software testing often depends on a test oracle to determine whether or not an output is correct. However, many real-world systems lack reliable or affordable oracles. Metamorphic testing (MT) alleviates this problem by using metamorphic relations (MRs), which examine the correctness of relations between outputs produc...

Temporal Metamorphic Testing for RAG-Based LLMs under Evolving Knowledge

Evaluating the temporal consistency of RetrievalAugmented Generation (RAG) systems is challenging because conventional evaluation methods rely on ground-truth answers, which are difficult to define under continuously evolving knowledge. This paper presents a temporal metamorphic testing framework for RAG-based large la...

GDGraph: Geometry-Enhanced Dual-View Graph for Molecular Representation Learning

Learning effective molecular representations is crucial for accurate property prediction in AI-aided drug discovery. However, most existing molecular pre-training methods are still primarily based on 2D topological graphs, limiting their ability to exploit 3D geometric information. Moreover, methods that do incorporate...
