Up-propagation is an algorithm for inverting and learning neural network generative models. Sensory input is processed by inverting a model that generates patterns from hidden var...
Object search is the task of eciently searching for a given 3D object in a given 3D environment by an agent equipped with a camera for target detection and, if the environment con...
We propose a novel probabilistic framework for learning
visual models of 3D object categories by combining appearance
information and geometric constraints. Objects are
represen...
