Compiler-Driven Simulation of Reconfigurable Hardware Accelerators

1 code implementation1 Feb 2022 Zhijing Li, Yuwei Ye, Stephen Neuendorffer, Adrian Sampso

As customized accelerator design has become increasingly popular to keep up with the demand for high performance computing, it poses challenges for modern simulator design to adapt to such a large variety of accelerators.

Optimizing JPEG Quantization for Classification Networks

no code implementations5 Mar 2020 Zhijing Li, Christopher De Sa, Adrian Sampson

While a long history of work has sought better Q-tables, existing work either seeks to minimize image distortion or to optimize for models of the human visual system.

Et Tu Alexa? When Commodity WiFi Devices Turn into Adversarial Motion Sensors

1 code implementation23 Oct 2018 Yanzi Zhu, Zhujun Xiao, Yuxin Chen, Zhijing Li, Max Liu, Ben Y. Zhao, Haitao Zheng

Our work demonstrates a new set of silent reconnaissance attacks, which leverages the presence of commodity WiFi devices to track users inside private homes and offices, without compromising any WiFi network, data packets, or devices.
