MOCHA framework distills VLM knowledge into lightweight detectors

Researchers have developed MOCHA, a novel distillation framework designed to transfer knowledge from large vision-language models (VLMs) to lightweight, vision-only detectors. This method addresses the computational demands of VLMs for real-time applications by extracting fused visual and textual embeddings from a frozen VLM teacher. MOCHA guides the student detector through a dual-objective loss, ensuring both accurate local alignment and global relational consistency across regions. The framework demonstrated significant improvements, outperforming prior baselines by an average of 10.1% in few-shot personalized detection benchmarks with minimal inference cost. AI

IMPACT Enables more efficient and accessible personalized object detection by transferring complex VLM capabilities to lightweight models.

    MOCHA: Multi-modal Objects-aware Cross-arcHitecture Alignment

    arXiv:2509.14001v5 Announce Type: replace-cross Abstract: Personalized object detection aims to adapt a general-purpose detector to recognize user-specific instances from only a few examples. Lightweight models often struggle in this setting due to their weak semantic priors, whi…
