Abstract: The present disclosure describes a patent management system and method for remediating insufficiency of input data for a machine learning system. A prediction to be performed is received from a user input. Relevant input data is determined to perform the prediction. The relevant input data is determined by applying filters based on the prediction to be performed. Prediction is performed by generating a plurality of predicted vectors. A confidence score for the generated plurality of predicted vectors is determined. If the confidence score is less than a predetermined threshold, the prediction is unreliable. The input data is expanded by gathering additional input data. The input data is expanded with the additional input data until the confidence score exceeds the predetermined threshold. A predicted output is generated with the expanded input data. The prediction output and the confidence score are provided for rendering.

Abstract: A secure network device management system and method include monitoring and validating commands to network devices before such commands are executed. The security system accumulates inputs from a network device intended for display on a terminal and provided by the network device in response to inputs from the terminal and received by the network device. When a control input to execute the command is received from the terminal, the security system reproduces the command from the accumulated inputs and compares the reproduced command to a command list to determine whether the command is authorized. If so, the security system provides the control input to the network device such that the network device executes the command. Otherwise, the security system may delete the command and transmit an alert to the terminal.

Abstract: A new diversity concept is provided for achieving accurate phase retrieval with a single shot acquisition. Multiple irradiance data are obtained by a diffractive grating or CGH designed to generate multiple diffraction orders with different diversity values. The effective filters associated with the individual diffraction orders from the diffractive grating or CGH are calculated. The effective filters are extracted by numerical propagation, and they preferably include both real and imaginary values, which signify both absorption and phase shift versus position in the filter plane. The reconstruction process utilizes accurate knowledge of the effective filters for each diffraction order for high quality reconstruction of the extrinsic phase.
