Quantum circuit representation of Bayesian networks

3 code implementations29 Apr 2020 Sima E. Borujeni, Saideep Nannapaneni, Nam H. Nguyen, Elizabeth C. Behrman, James E. Steck

We develop a systematic method for designing a quantum circuit to represent a generic discrete Bayesian network with nodes that may have two or more states, where nodes with more than two states are mapped to multiple qubits.

A Scale Invariant Flatness Measure for Deep Network Minima

no code implementations6 Feb 2019 Akshay Rangamani, Nam H. Nguyen, Abhishek Kumar, Dzung Phan, Sang H. Chin, Trac. D. Tran

It has been empirically observed that the flatness of minima obtained from training deep networks seems to correlate with better generalization.

When Does Stochastic Gradient Algorithm Work Well?

no code implementations18 Jan 2018 Lam M. Nguyen, Nam H. Nguyen, Dzung T. Phan, Jayant R. Kalagnanam, Katya Scheinberg

In this paper, we consider a general stochastic optimization problem which is often at the core of supervised learning, such as deep learning and linear classification.

Collaborative Multi-sensor Classification via Sparsity-based Representation

no code implementations29 Oct 2014 Minh Dao, Nam H. Nguyen, Nasser M. Nasrabadi, Trac. D. Tran

In this paper, we propose a general collaborative sparse representation framework for multi-sensor classification, which takes into account the correlations as well as complementary information between heterogeneous sensors simultaneously while considering joint sparsity within each sensor's observations.
