Generative Marginalization Models

1 code implementation19 Oct 2023 Sulin Liu, Peter J. Ramadge, Ryan P. Adams

We introduce marginalization models (MaMs), a new family of generative models for high-dimensional discrete data.

Sparse Bayesian Optimization

1 code implementation3 Mar 2022 Sulin Liu, Qing Feng, David Eriksson, Benjamin Letham, Eytan Bakshy

Bayesian optimization (BO) is a powerful approach to sample-efficient optimization of black-box objective functions.

ProBF: Learning Probabilistic Safety Certificates with Barrier Functions

1 code implementation22 Dec 2021 Athindran Ramesh Kumar, Sulin Liu, Jaime F. Fisac, Ryan P. Adams, Peter J. Ramadge

In practice, we have inaccurate knowledge of the system dynamics, which can lead to unsafe behaviors due to unmodeled residual dynamics.

Task-Agnostic Amortized Inference of Gaussian Process Hyperparameters

1 code implementation NeurIPS 2020 Sulin Liu, Xingyuan Sun, Peter J. Ramadge, Ryan P. Adams

One of the appeals of the GP framework is that the marginal likelihood of the kernel hyperparameters is often available in closed form, enabling optimization and sampling procedures to fit these hyperparameters to data.

The Landscape of Matrix Factorization Revisited

no code implementations27 Feb 2020 Hossein Valavi, Sulin Liu, Peter J. Ramadge

We show that, in contrast to the general situation, the minimum eigenvalue of strict saddles in $\mathcal{M}_{0}$ is uniformly bounded below zero.

Distributed Multi-Task Relationship Learning

no code implementations13 Dec 2016 Sulin Liu, Sinno Jialin Pan, Qirong Ho

Due to heavy communication caused by transmitting the data and the issue of data privacy and security, it is impossible to send data of different task to a master machine to perform multi-task learning.
