Bridging the Semantic Chasm: Synergistic Conceptual Anchoring for Generalized Few-Shot and Zero-Shot OOD Perception

Alexandros Christoforos, Sarah Jenkins, Michael Brown, Tuan Pham, David Chen

TL;DR

This work tackles the challenge of cross-modal alignment collapse in Vision-Language Models when encountering Out-of-Distribution concepts. It introduces SynerNet, a four-agent framework comprising Visual Perception, Linguistic Context, Nominal Embedding, and a Global Coordinator, connected via a structured message-passing protocol to dynamically adapt cross-modal representations. Key innovations include a multi-agent latent-space nomenclature acquisition, a context-interchange mechanism for few-shot learning, and an adaptive dynamic equilibrium that balances contrastive and classification objectives. On the VISTA-Beyond benchmark, SynerNet delivers consistent improvements in both few-shot and zero-shot settings (1.2%–5.4% gains), demonstrating robust cross-modal fusion and practical potential for open-world perception tasks.

Abstract

This manuscript presents a pioneering Synergistic Neural Agents Network (SynerNet) framework designed to mitigate the phenomenon of cross-modal alignment degeneration in Vision-Language Models (VLMs) when encountering Out-of-Distribution (OOD) concepts. Specifically, four specialized computational units - visual perception, linguistic context, nominal embedding, and global coordination - collaboratively rectify modality disparities via a structured message-propagation protocol. The principal contributions encompass a multi-agent latent space nomenclature acquisition framework, a semantic context-interchange algorithm for enhanced few-shot adaptation, and an adaptive dynamic equilibrium mechanism. Empirical evaluations conducted on the VISTA-Beyond benchmark demonstrate that SynerNet yields substantial performance augmentations in both few-shot and zero-shot scenarios, exhibiting precision improvements ranging from 1.2% to 5.4% across a diverse array of domains.

  • Figure 1: Quantitative evaluation of cross-dataset generalization capabilities. We report the top-1 classification accuracy across diverse Out-of-Distribution (OOD) domains (e.g., Insects, Landmarks, Satellite) under varying few-shot settings ranging from 1-shot to 16-shot. The proposed SynerNet framework (solid red line) consistently surpasses state-of-the-art adaptation paradigms, such as CoOp and CLIP-Adapter, exhibiting superior robustness against severe domain shifts and effectively mitigating the performance degradation typically observed in zero-shot transfer scenarios.
  • Figure 2: t-SNE visualization of cross-modal latent space alignment for OOD concepts. (Left) The baseline OpenCLIP model exhibits severe alignment collapse, where text embeddings (represented by triangles) fail to map into the corresponding visual feature clusters (represented by circles), creating a distinct semantic gap. (Right) Our SynerNet successfully rectifies this disparity through collaborative agent interaction, pulling semantic anchors into the visual manifold to establish tight, discriminative cross-modal clusters for previously unseen categories, thereby validating the efficacy of the proposed Nominal Embedding Unit.
