Latest Patents

One of Yanwen Fan's latest patents is titled "Neural architecture search via similarity-based operator ranking." This innovative approach addresses the challenges associated with supernet-based differentiable methods, particularly the mismatch between architecture and weights due to weight sharing. His methodology employs a similarity-based operator ranking that utilizes statistical random comparison to approximate each layer's output in the supernet. This technique prunes operators that minimally affect feature distribution discrepancies and incorporates a fair sampling process to mitigate the Matthew effect observed in previous supernet approaches.

Another notable patent is "Cursor-based adaptive quantization for deep neural networks." This invention focuses on reducing the storage and computational burdens of deep neural networks by decreasing the bit width through a novel cursor-based adaptive quantization mechanism. The process is formulated as a differentiable architecture search (DAS) that adaptively determines the quantization bit for each layer. By employing a new loss function, the search process optimizes both accuracy and parameter size, ultimately reducing quantization noise and avoiding local convergence issues.
