A MODEL OF QUANTUM GRAVITY WITH EMERGENT SPACETIME

Abstract We construct a model of quantum gravity in which dimension, topology and geometry of spacetime are dynamical.The microscopic degree of freedom is a real rectangular matrix whose rows label internal flavours, and columns label spatial sites.In the limit that the size of the matrix is large, the sites can collectively form a spatial manifold

The information bottleneck method is a generic clustering framework from the field of machine learning which allows compressing an observed quantity while retaining Denim as much of the mutual information it shares with the quantity of primary relevance as possible.The framework was recently used to design message-passing decoders for low-density p
