Abstract: A powered ankle-foot prosthesis and associated methods of use are described herein. Such prostheses can employ an actuator and elastic components, the actuator being controlled to deliver net positive work to propel the wearing amputee forward and the elastic components being used to store and release negative energy to improve efficiency. Elastic components can be linear springs coupled with a cam and configured in parallel to the actuator. The cam profile can be designed to generate a desired spring torque versus angle curve rather than a spring stroke versus angle curve, thereby reproducing human ankle controlled dorsiflexion stiffness. Such configurations improve system energy efficiency and reduce both actuator torque and power requirements. Such prostheses can also operate in a passive mode, in which a nearly normal gait can be achieved even without powered assist.

Abstract: Various implementations relate to asynchronous training of a machine learning model. A server receives feedback data generated by training the machine learning model from a worker. The feedback data are obtained by the worker with its own training data and are associated with previous values of a set of parameters of the machine learning model at the worker. The server determines differences between the previous values and current values of the set of parameters at the server. The current value may have been updated for once or more due to operation of other workers. Then, the server can update the current values of the set of parameters based on the feedback data and the differences between values of the set of parameters. Thus, the updating does not only take the training result of each worker into consideration but also makes proper compensation for delay between different workers.
