Expressive power of complex-valued restricted Boltzmann machines for solving nonstoquastic Hamiltonians
نویسندگان
چکیده
Variational Monte Carlo with neural quantum states is one of the most powerful tools for solving ground state many-body Hamiltonians. However, performance method on frustrated Hamiltonians remains significantly worse than that sign-free Hamiltonians, even though itself free from sum-over alternating signs. Here, authors systematically study numerical subtleties in restricted Boltzmann machine based variational sign problem and unveil how phases are related to numerics.

Expressive Power and Approximation Errors of Restricted Boltzmann Machines
We present explicit classes of probability distributions that can be learned by Restricted Boltzmann Machines (RBMs) depending on the number of units that they contain, and which are representative for the expressive power of the model. We use this to show that the maximal Kullback-Leibler divergence to the RBM model with n visible and m hidden units is bounded from above by (n−1)− log(m+1). In...
متن کاملGeometry and expressive power of conditional restricted Boltzmann machines
We consider the causal structure of the sensorimotor loop (SML) and represent the agent’s policies in terms of conditional restricted Boltzmann machines (CRBMs). CRBMs can model non-trivial conditional distributions on high dimensional input-output spaces with relatively few parameters. In addition, their Glauber dynamics can be computed efficiently to produce approximate samples. We discuss va...
متن کاملDiscrete restricted Boltzmann machines
We describe discrete restricted Boltzmann machines: probabilistic graphical models with bipartite interactions between visible and hidden discrete variables. Examples are binary restricted Boltzmann machines and discrete näıve Bayes models. We detail the inference functions and distributed representations arising in these models in terms of configurations of projected products of simplices and ...
متن کاملSupervised Restricted Boltzmann Machines
We propose in this paper the supervised restricted Boltzmann machine (sRBM), a unified framework which combines the versatility of RBM to simultaneously learn the data representation and to perform supervised learning (i.e., a nonlinear classifier or a nonlinear regressor). Unlike the current state-of-the-art classification formulation proposed for RBM in (Larochelle et al., 2012), our model is...
متن کاملCardinality Restricted Boltzmann Machines
The Restricted Boltzmann Machine (RBM) is a popular density model that is also good for extracting features. A main source of tractability in RBM models is that, given an input, the posterior distribution over hidden variables is factorizable and can be easily computed and sampled from. Sparsity and competition in the hidden representation is beneficial, and while an RBM with competition among ...
