Dense Pruning of Pointwise Convolutions in the Frequency Domain

no code implementations16 Sep 2021 Mark Buckler, Neil Adit, Yuwei Hu, Zhiru Zhang, Adrian Sampson

Our key insights are that 1) pointwise convolutions commute with frequency transformation and thus can be computed in the frequency domain without modification, 2) each channel within a given layer has a different level of sensitivity to frequency domain pruning, and 3) each channel's sensitivity to frequency pruning is approximately monotonic with respect to frequency.

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.

High Five: Improving Gesture Recognition by Embracing Uncertainty

no code implementations25 Oct 2017 Diman Zad Tootaghaj, Adrian Sampson, Todd Mytkowicz, Kathryn S. McKinley

We introduce a new statistical quantization approach that mitigates these problems by (1) during training, producing gesture-specific codebooks, HMMs, and error models for gesture sequences; and (2) during classification, exploiting the error model to explore multiple feasible HMM state sequences.
