Title: Method for segmental control of auxillary feedwater flow
Inventor: Xuelian Shang
IPC: G21D3/04
Filed: 2015-12-15
Abstract: A method of control of the auxiliary water in nuclear power plants is characterized in that a solenoid valve of an auxiliary feedwater flow control valve is energized via an automatic interlock signal after an auxiliary feedwater system is put into operation. A control system detects the water level in a steam generator and performs segmental control of opening of the auxiliary feedwater control valve in response to a preset value so as to maintain the water level in the steam generator. After the control valve is removed out of the control mode, the solenoid valve of the auxiliary feedwater flow control valve is de-energized and the control valve is restored to fully-open position. The control of the valve based on detecting of the water level can have four detectors with the water level change being based on a two out of four voting logic to overcome any signal faults, thus allowing for a redundancy configuration. The system may also be designed with a manual adjustment in addition to the automatic control.

Title: Communication efficient federated learning
Inventor: HUGH BRENDAN MCMAHAN
IPC: G06N3/08
Filed: 2017-09-26
Abstract: A method of communication efficient distributed machine learning comprises obtaining 312 by a client device global values for parameters of a machine learned model, e.g. a neural network or support vector machine. The client computing device trains the machine learned model based at least in part on a training dataset stored locally on the client machine, and determines 314 an update matrix that is descriptive of updated parameter values. The update matrix may have a pre-defined structure such as being a low-rank or sparse matrix. The client then communicates 316 information descriptive of the update matrix to a server where the global model may by revised based on the update data. Transmitting only the parameter updates means less data has to be sent by client devices, and conducting the learning at the client devices means that the potentially privacy sensitive local training data doesnt need to be transmitted.
