Publication number: 20210253046Abstract: In general, one or more loads, such as a sensor suite of an autonomous (or semi-autonomous) vehicle, may be configured to draw power from a supercapacitor. A switching mechanism can selectively connect or disconnect the one or more loads and the supercapacitor from a voltage source of a vehicle power system. By systematically disconnecting the voltage source from the supercapacitor and the one or more loads, the exposure of the voltage source to the one or more loads is minimized. Accordingly, the exposure of the voltage source of the vehicle power system to potentially damaging short circuits or power surges that may arise in relation to the one or more loads can also be minimized.Type: ApplicationFiled: January 4, 2021Publication date: August 19, 2021Applicant: Lyft, Inc.Inventors: Chen-yu Hsieh, Catalin Popovici

Patent number: 11048978Abstract: Methods and systems for meta-learning are described for automating learning of child tasks with a single neural network. The order in which tasks are learned by the neural network can affect performance of the network, and the meta-learning approach can use a task-level curriculum for multi-task training. The task-level curriculum can be learned by monitoring a trajectory of loss functions during training. The meta-learning approach can learn to adapt task loss balancing weights in the course of training to get improved performance on multiple tasks on real world datasets. Advantageously, learning to dynamically balance weights among different task losses can lead to superior performance over the use of static weights determined by expensive random searches or heuristics. Embodiments of the meta-learning approach can be used for computer vision tasks or natural language processing tasks, and the trained neural networks can be used by augmented or virtual reality devices.Type: GrantFiled: November 9, 2018Date of Patent: June 29, 2021Assignee: Magic Leap, Inc.Inventors: Andrew Rabinovich, Vijay Badrinarayanan, Srivignesh Rajendran, Chen-Yu Lee
