A restricted Boltzmann machine (RBM) is a generative stochastic artificial neural network that can learn a probability distribution over its set of inputs.RBMs were initially invented under the name Harmonium by Paul Smolensky in 1986, and rose to prominence after Geoffrey Hinton and collaborators invented fast learning algorithms for them in the mid-2000. A Boltzmann machine is a network of symmetrically connected, neuron-like units that make stochastic decisions about whether to be on or off. �s�D����CsK�m���y��M�,>g���1iyeD6��(Fr%�ˢt�O��R�Ύ)t����F[�6}�z��X��� Nb���WN����{Iǃ}�K�N:�� y�d���h�!�:H�ar��Y������+���~j@�����)���(�����pt�'QǶ�7�-�+V��d�����f�#���h+�d2��Fx�$����О��xG��5.���>����:�����"m��qRL�|Uu�Y5�b�AL����|;���%e�f�������B"0����5�3�VӉ�? Boltzmann Machine towards critical behaviour by maximizing the heat capacity of the network. Using Boltzmann machines to develop alternative generative models for speaker recognition promises to be an interesting line of research. A Boltzmann machine (also called stochastic Hopfield network with hidden units or Sherrington–Kirkpatrick model with external field or stochastic Ising-Lenz-Little model) is a type of stochastic recurrent neural network. The latter were introduced as bidirectionally connected networks of stochastic processing units, which can be interpreted as neural network models [1,22]. Due to the non-commutative nature of quantum mechanics, the training process of the Quantum Boltzmann Machine (QBM) can become nontrivial. Una máquina de Boltzmann es un tipo de red neuronal recurrente estocástica.El nombre le fue dado por los investigadores Geoffrey Hinton y Terry Sejnowski.Las máquinas de Boltzmann pueden considerarse como la contrapartida estocástica y generativa de las redes de Hopfield.Fueron de los primeros tipos de redes neuronales capaces de aprender mediante … stream x 2 X be a vector, where X is a space of the variables under investigation (they will be claried later).
