Summary

A new video copy detection framework utilizes differentiable Logic Gate Networks (LGNs) to address the computational and memory limitations of deep neural networks in high-throughput systems. This approach integrates aggressive frame miniaturization, binary preprocessing, and a trainable LGN embedding model that learns logical operations and interconnections. Once trained, the model discretizes into a purely Boolean circuit, enabling extremely fast and memory-efficient inference. Experimental evaluations across various datasets and difficulty levels show that LGN-based models achieve competitive or superior accuracy and ranking performance compared to existing models. Furthermore, they produce descriptors several orders of magnitude smaller and achieve inference speeds over 11,000 samples per second, positioning logic-based models as a viable alternative for scalable video copy detection.

Key takeaway

For AI Engineers developing high-throughput video processing systems, consider integrating Logic Gate Networks (LGNs) to significantly reduce descriptor size and boost inference speeds. Your existing deep learning models might be replaced or augmented by LGN-based solutions, offering superior resource efficiency without sacrificing accuracy, particularly for large-scale video copy detection tasks.
