Latest Patents

One of Ballard's latest patents focuses on "Environment navigation using reinforcement learning." This patent outlines methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for training a reinforcement learning system. The method involves receiving an observation image that characterizes the current state of the environment. It processes this input using an action selection policy neural network to generate an action selection output. Additionally, it employs a geometry-prediction neural network to predict a value of a feature of the environment's geometry. The process includes backpropagating a gradient of a geometry-based auxiliary loss into the action selection policy neural network to determine an update for the current values of the network parameters.
