Value-Driven Mixed-Precision Quantization for Patch-Based Inference on Microcontrollers

no code implementations24 Jan 2024 Wei Tao, Shenglin He, Kai Lu, Xiaoyang Qu, Guokuan Li, Jiguang Wan, Jianzong Wang, Jing Xiao

In addition, for patches without outlier values, we utilize value-driven quantization search (VDQS) on the feature maps of their following dataflow branches to reduce search time.

GAIA: Delving into Gradient-based Attribution Abnormality for Out-of-distribution Detection

1 code implementation NeurIPS 2023 Jinggang Chen, Junjie Li, Xiaoyang Qu, Jianzong Wang, Jiguang Wan, Jing Xiao

This perspective is motivated by our observation that gradient-based attribution methods encounter challenges in assigning feature importance to OOD data, thereby yielding divergent explanation patterns.
