arXiv:1909.08210v4 Announce Type: replace Abstract: A restricted Boltzmann machine (RBM) is a two-layer neural network with shared weights and has been extensively studied for dimensionality reduction, data representation and recommendation systems in the literature. The traditional RBM requires a probabilistic interpretation of the values on both layers and a Markov chain Monte Carlo (MCMC) procedure to generate samples during the training. The contrastive divergence (CD) is efficient to train the RBM but its convergence has not been proved mathematically. In this paper, using a maximum a pos
This paper re-evaluates a foundational unsupervised learning model (RBM) addressing its interpretability and training limitations, indicating a renewed focus on its theoretical underpinnings.
Improved RBM training and theoretical understanding can lead to more robust and powerful dimensionality reduction and data representation techniques, impacting various AI applications.
The reformulation offers a path towards unifying linear and non-linear dimensionality reduction within the RBM framework, potentially simplifying model selection and improving performance.
