New PSCA Framework Enhances Domain Adaptive Retrieval with Semantic Alignment

Researchers have developed a new framework called Prototype-Based Semantic Consistency Alignment (PSCA) to improve domain adaptive retrieval. This method addresses limitations in existing approaches by focusing on class-level semantic alignment rather than just pair-wise sample alignment. PSCA incorporates pseudo-label reliability and geometric guidance to assess label correctness, and it reconstructs features before quantization to enhance the quality of learned hash codes. The framework's two-stage process ensures unified binary hash codes across different domains, demonstrating superior performance in experiments. AI
