  • Generative adversarial networks (GAN): A neural network that generates new data by pitting a generator network against a discriminator network.
  • Restricted Boltzmann machines (RBM): A type of stochastic neural network that models the probability distribution of binary data.
  • Hidden Markov models (HMM): A probabilistic model that represents a sequence of observations using a set of hidden states.
  • Autoregressive (AR) models: A type of time-series model that predicts future values based on past observations.
  • Recurrent neural networks (RNN): A type of neural network that models sequential data by maintaining a hidden state.
