MMGist: A Comprehensive Multimodal Benchmark for 2027

MMGist is a curated multimodal benchmark with 7,262 items, designed to address flaws in existing vision-language benchmarks. It reduces evaluation size by 69% and improves cross-model discrimination by 78%, while preserving model rankings with a Spearman correlation of 0.98. The benchmark highlights visual logic as a key weakness and emphasizes the importance of visual dependency, discriminative power, and reliability in evaluation.

PRIME: Evaluating Prompt Resolution in Conflicting Instructions

PRIME introduces a framework to analyze how large language models handle conflicting instructions by generating calibrated conflicts in response length, format, and reasoning. The study finds that conflict type has a greater impact on model behavior than model size, revealing diverse failure modes across conflict categories. Results highlight the need for conflict awareness and suggest instruction following cannot be reliably assessed through isolated benchmarks alone.

Generative Robust Optimisation Framework

Generative Robust Optimisation (GRO) introduces a deep generative model to define uncertainty sets, capturing nonlinear correlations, asymmetry, and multimodality. A five-point evaluation framework assesses neural network-based uncertainty sets across reconstruction fidelity, distribution matching, latent regularity, robust relevance, and computational tractability, with experiments validating GRO's effectiveness in production planning and facility location.

Concept-Constrained Prompt Learning for Few-Shot CLIP Adaptation

CCPL introduces a lightweight framework that anchors class prompts to frozen concept prototypes, improving few-shot CLIP adaptation. It achieves better base-to-new performance on DTD and EuroSAT compared to CoOp, with consistent gains from text-space concept regularization, while maintaining neutrality on OxfordPets. The method uses concept dropout and controllable ensemble fusion at inference, with results sensitive to dataset semantics and protocol.

CWE-Level Generalisation in Syscall-Based HIDS

A one-class anomaly detector trained on normal behavior of CVEs sharing a CWE class can generalise to unseen CVEs within the same class, but effectiveness varies by CWE family. The CWE-307 detector achieves F1 = 0.6976 at 5% false positive rate, while CWE-89 and CWE-434 perform poorly, with F1 ≤ 0.21. Cross-CVE transfer is direction-dependent and driven more by the breadth of the source normal profile than the CWE category.
