Accurate and Conservative Estimates of MRF Log-likelihood using Reverse Annealing
Yuri Burda, Roger B. Grosse, Ruslan Salakhutdinov
Markov random fields (MRFs) are difficult to evaluate as generative models because computing the test log-probabilities requires the intractable partition function. Annealed import…
Modified Bloch-Redfield Master Equation for Incoherent Excitation of Multilevel Quantum Systems
Timur V. Tscherbul, Paul Brumer
We present an efficient theoretical method for calculating the time evolution of the density matrix of a multilevel quantum system weakly interacting with incoherent light. The met…
Approximate Ultrametricity for Random Measures and Applications to Spin Glasses
Aukosh Jagannath
In this paper, we introduce a notion called "Approximate Ultrametricity" which encapsulates the phenomenology of a sequence of random probability measures having supports that beha…
A uniform construction of smooth integral models and a recipe for computing local densities
Sungmun Cho
In this paper, we explain a simple and uniform construction of a smooth integral model associated to a quadratic, (anti)-hermitian, and (anti)-quaternionic hermitian lattice define…
The JCMT Gould Belt Survey: Evidence for radiative heating in Serpens MWC 297 and its influence on local star formation
D. Rumble, J. Hatchell, R. A. Gutermuth +61
We present SCUBA-2 450micron and 850micron observations of the Serpens MWC 297 region, part of the JCMT Gould Belt Survey of nearby star-forming regions. Simulations suggest that r…
Optimizing User Association and Spectrum Allocation in HetNets: A Utility Perspective
Yicheng Lin, Wei Bao, Wei Yu +1
The joint user association and spectrum allocation problem is studied for multi-tier heterogeneous networks (HetNets) in both downlink and uplink in the interference-limited regime…
