Hierarchical Disentangled Representation for Invertible Image Denoising and Beyond

no code implementations31 Jan 2023 Wenchao Du, Hu Chen, Yi Zhang, H. Yang

More specifically, we decompose the noisy image into clean low-frequency and hybrid high-frequency parts with an invertible transformation and then disentangle case-specific noise and high-frequency components in the latent space.

Avoiding Overlap in Data Augmentation for AMR-to-Text Generation

no code implementations ACL 2021 Wenchao Du, Jeffrey Flanigan

We propose methods for excluding parts of Gigaword to remove this overlap, and show that our approach leads to a more realistic evaluation of the task of AMR-to-text generation.

Top-Down Structurally-Constrained Neural Response Generation with Lexicalized Probabilistic Context-Free Grammar

no code implementations NAACL 2019 Wenchao Du, Alan W. black

We consider neural language generation under a novel problem setting: generating the words of a sentence according to the order of their first appearance in its lexicalized PCFG parse tree, in a depth-first, left-to-right manner.
