Learning a peripersonal space representation using Conditional Restricted Boltzmann Machine
Original language description
We present a neural network learning architecture composed of a Restricted Boltzmann Machine (RBM) and a Conditional RBM (CRBM) that performs multisen- sory integration and prediction, motivated by the problem of learning a representation of defensive peripersonal space. This work follows up on our previous work (Straka and Hoffmann 2017) where we proposed a network composed of a RBM and a feedforward neural network (FFNN). In this work, with a similar 2D simulated scenario, we sought to replace the FFNN with an RBM-like module and opted for the CRBM which is responsible for making a temporal prediction. We demonstrate that the new architecture is capable of learning to map from visual and tactile inputs at a previous time step (without tactile activation) to future activations with the visual stimulus at the “skin” and corresponding tactile activation, including the confidence of the predictions.
