Publication number: 20240127153Abstract: Disclosed are techniques, and related systems, for developing and implementing a unified framework for quantifying risk in machine learning models, such as deep neural networks. The framework can be easy-to-use and flexible to apply to different types of machine learning models. The framework can be used to automatically assess different forms of risk in parallel, including but not limited to aleatoric uncertainty, epistemic uncertainty, and/or vacuitic uncertainty. To that end, the disclosed framework provides wrappers that compose different automatic risk assessment algorithms. The obtained risk estimates can be used, for example, for: providing a deeper insight into decision boundaries of neural networks; performing downstream tasks by integrating the risk estimates back into a learning lifecycle for the model to improve robustness and generalization; and/or improving safety by identifying potential model failures based on the risk values.Type: ApplicationFiled: September 29, 2023Publication date: April 18, 2024Inventors: Alexander Andre Amini, Sadhana Lolla, Iaroslav Elistratov, Alejandro Perez, Elaheh Ahmadi, Daniela Rus

Patent number: 9697940Abstract: Apparatus and methods for generating a uniform magnetic field are provided herein. In certain configurations, a magnetic structure includes one or more pairs of magnets positioned within a housing. The magnets of each pair are arranged in parallel and include poles that are reversed in polarity relative to one another. For example, in certain implementations, a first pair of magnets includes a first magnet and a second magnet arranged side by side, with a north pole of the first magnet adjacent a south pole of the second magnet and with a south pole of the first magnet adjacent a north pole of the second magnet. The housing is implemented using a magnetic redirecting material, which can confine magnetic flux and reduce stray magnetic fields. The magnetic structure can be used to generate a magnetic field that is substantially uniform in a region of interest.Type: GrantFiled: August 20, 2014Date of Patent: July 4, 2017Assignee: Analog Devices GlobalInventors: Alexander Perez Paran, Brigido Prudente Sarino, Jr., Darwin Punla Tolentino
