VCG: Multimodal Retrieval Framework Solves Extreme Cold-Start Problem for E-Commerce Video Feeds

E-commerce platforms are shifting to video feeds but face extreme cold-start problems because new videos lack interaction history. The VCG system, described in a recent arXiv paper, uses a CLIP-based multimodal retrieval engine to map users and videos into a shared semantic space, enabling zero-shot retrieval. Online A/B testing showed a 50% uplift in deep video completion, demonstrating effective mitigation of engagement biases.
