Patent number: 11216697Abstract: Techniques for building a backward compatible and backfill-free image search system are described. According to some embodiments, a backwards compatible training system trains a new embedding model to be backward compatible with the face embeddings (e.g., floating-point vectors) generated by a previous embedding model. In one embodiment, backwards compatible training uses a classifier of the previous embedding model as a form of constraint in the training of the new embedding model.Type: GrantFiled: March 11, 2020Date of Patent: January 4, 2022Assignee: Amazon Technologies, Inc.Inventors: Yantao Shen, Yuanjun Xiong, Siqi Deng, Wei Xia, Shuo Yang, Yifan Xing, Wei Li, Stefano Soatto

Patent number: 7367242Abstract: An active micro-force sensor is provided for use on a micromanipulation device. The active micro-force sensor includes a cantilever structure having an actuator layer of piezoelectric material and a sensing layer of piezoelectric material bonded together. When an external force is exerted on the sensor, the sensor deforms and an applied force signal is recorded by the sensing layer. The applied force signal is then fed back to the actuating layer of the sensor via a servoed transfer function or servo controller, so that a counteracting deformation can be generated by the bending moment from the servoed actuating layer to quickly balance the deformation caused by the external micro-force.Type: GrantFiled: February 27, 2006Date of Patent: May 6, 2008Assignee: Board of Trustees operating Michigan State UniversityInventors: Ning Xi, Yantao Shen
