Unsupervised Learning of Structured Representations via Closed-Loop Transcription

1 code implementation30 Oct 2022 Shengbang Tong, Xili Dai, Yubei Chen, Mingyang Li, Zengyi Li, Brent Yi, Yann Lecun, Yi Ma

This paper proposes an unsupervised method for learning a unified representation that serves both discriminative and generative purposes.

Neural Manifold Clustering and Embedding

1 code implementation24 Jan 2022 Zengyi Li, Yubei Chen, Yann Lecun, Friedrich T. Sommer

We argue that achieving manifold clustering with neural networks requires two essential ingredients: a domain-specific constraint that ensures the identification of the manifolds, and a learning algorithm for embedding each manifold to a linear subspace in the feature space.

A Neural Network MCMC sampler that maximizes Proposal Entropy

1 code implementation7 Oct 2020 Zengyi Li, Yubei Chen, Friedrich T. Sommer

However, in the continuous case, unfavorable geometry of the target distribution can greatly limit the efficiency of MCMC methods.

Complex Amplitude-Phase Boltzmann Machines

no code implementations4 May 2020 Zengyi Li, Friedrich T. Sommer

We extend the framework of Boltzmann machines to a network of complex-valued neurons with variable amplitudes, referred to as Complex Amplitude-Phase Boltzmann machine (CAP-BM).

Learning Energy-Based Models in High-Dimensional Spaces with Multi-scale Denoising Score Matching

2 code implementations17 Oct 2019 Zengyi Li, Yubei Chen, Friedrich T. Sommer

Recently, \citet{song2019generative} have shown that a generative model trained by denoising score matching accomplishes excellent sample synthesis, when trained with data samples corrupted with multiple levels of noise.
