Self-Supervised Unseen Object Instance Segmentation via Long-Term Robot Interaction

1 code implementation7 Feb 2023 Yangxiao Lu, Ninad Khargonkar, Zesheng Xu, Charles Averill, Kamalesh Palanisamy, Kaiyu Hang, Yunhui Guo, Nicholas Ruozzi, Yu Xiang

By applying multi-object tracking and video object segmentation on the images collected via robot pushing, our system can generate segmentation masks of all the objects in these images in a self-supervised way.

Lifted Hybrid Variational Inference

1 code implementation8 Jan 2020 Yuqiao Chen, Yibo Yang, Sriraam Natarajan, Nicholas Ruozzi

We demonstrate that the proposed variational methods are both scalable and can take advantage of approximate model symmetries, even in the presence of a large amount of continuous evidence.

Automatic Parameter Tying in Neural Networks

no code implementations ICLR 2018 Yibo Yang, Nicholas Ruozzi, Vibhav Gogate

Recently, there has been growing interest in methods that perform neural network compression, namely techniques that attempt to substantially reduce the size of a neural network without significant reduction in performance.

Sparse Approximate Conic Hulls

no code implementations NeurIPS 2017 Greg Van Buskirk, Benjamin Raichel, Nicholas Ruozzi

Equivalently, given the matrix X, consider the problem of finding a small subset, S, of the columns of X such that the conic hull of S \eps-approximates the conic hull of the columns of X, i. e., the distance of every column of X to the conic hull of the columns of S should be at most an \eps-fraction of the angular diameter of X.

Exactness of Approximate MAP Inference in Continuous MRFs

no code implementations NeurIPS 2015 Nicholas Ruozzi

Computing the MAP assignment in graphical models is generally intractable.

Making Pairwise Binary Graphical Models Attractive

no code implementations NeurIPS 2014 Nicholas Ruozzi, Tony Jebara

The later has better convergence properties but typically provides poorer estimates.

The Bethe Partition Function of Log-supermodular Graphical Models

no code implementations NeurIPS 2012 Nicholas Ruozzi

Sudderth, Wainwright, and Willsky conjectured that the Bethe approximation corresponding to any fixed point of the belief propagation algorithm over an attractive, pairwise binary graphical model provides a lower bound on the true partition function.
