Optimally Controllable Perceptual Lossy Compression

1 code implementation21 Jun 2022 Zeyu Yan, Fei Wen, Peilin Liu

We prove that arbitrary points of the D-P tradeoff bound can be achieved by a simple linear interpolation between the outputs of a minimum MSE decoder and a specifically constructed perfect perceptual decoder.

Optimal Transport for Unsupervised Denoising Learning

1 code implementation4 Aug 2021 Wei Wang, Fei Wen, Zeyu Yan, Peilin Liu

Toward answering this question, this work proposes a criterion for unsupervised denoising learning based on the optimal transport theory.

On Perceptual Lossy Compression: The Cost of Perceptual Reconstruction and An Optimal Training Framework

1 code implementation5 Jun 2021 Zeyu Yan, Fei Wen, Rendong Ying, Chao Ma, Peilin Liu

This paper provides nontrivial results theoretically revealing that, \textit{1}) the cost of achieving perfect perception quality is exactly a doubling of the lowest achievable MSE distortion, \textit{2}) an optimal encoder for the "classic" rate-distortion problem is also optimal for the perceptual compression problem, \textit{3}) distortion loss is unnecessary for training a perceptual decoder.

Mention Extraction and Linking for SQL Query Generation

no code implementations EMNLP 2020 Jianqiang Ma, Zeyu Yan, Shuai Pang, Yang Zhang, Jianping Shen

On the WikiSQL benchmark, state-of-the-art text-to-SQL systems typically take a slot-filling approach by building several dedicated models for each type of slots.
