Diagram of a restricted Boltzmann machine with three visible units and four hidden units (no bias units) A restricted Boltzmann machine (RBM) (also called a restricted Sherrington–Kirkpatrick model with external field or restricted stochastic Ising–Lenz–Little model) is a generative stochastic artificial neural network that can learn a probability distribution over its set of inputs.
Boltzmann distribution % of lowest energy conformation in a two component equilibrating system at various temperatures (°C, color) and energy difference in kcal/mol (x-axis) The fractional population distribution of different conformers follows a Boltzmann distribution : [ 14 ]
This is not a restricted Boltzmann machine. A Boltzmann machine, like a Sherrington–Kirkpatrick model, is a network of units with a total "energy" (Hamiltonian) defined for the overall network. Its units produce binary results. Boltzmann machine weights are stochastic. The global energy in a Boltzmann machine is identical in form to that of ...
A restricted Boltzmann machine is a bipartite generative model specified over an undirected graph. Applications. The framework of the models, ...
In machine learning (ML), feature learning or representation learning [2] is a set of techniques that allow a system to automatically discover the representations needed for feature detection or classification from raw data. This replaces manual feature engineering and allows a machine to both learn the features and use them to perform a ...
For a system (such as a molecule or solid) with uncoupled vibrational modes the vibrational partition function is defined by =, where is the absolute temperature of the system, is the Boltzmann constant, and , is the energy of the jth mode when it has vibrational quantum number =,,, ….
Reverse annealing has been used as well to solve a fully connected quantum restricted Boltzmann machine. [66] Inspired by the success of Boltzmann machines based on classical Boltzmann distribution, a new machine learning approach based on quantum Boltzmann distribution of a transverse-field Ising Hamiltonian was recently proposed.
