  • Patent number: 11977374
    Abstract: A system for controlling an operation of a machine for performing a task is disclosed. The system submits a sequence of control inputs to the machine and receives a feedback signal. The system further determines, at each control step, a current control input for controlling the machine based on the feedback signal including a current measurement of a current state of the system by applying a control policy transforming the current measurement into the current control input based on current values of control parameters in a set of control parameters of a feedback controller. Furthermore, the system may iteratively update a state of the feedback controller defined by the control parameters using a prediction model predicting values of the control parameters and a measurement model updating the predicted values to produce the current values of the control parameters that explain the sequence of measurements according to a performance objective.

  • Patent number: 11928178
    Abstract: A wafer is prepared, and a thickness shape of the prepared wafer at each position in a radial direction is measured for each of a predetermined number of angles into which 360 degrees of a circumference around the center of the wafer are divided. The thickness shape obtained by a measuring machine for each angle is approximated with a sixth or higher order polynomial, and a function of the wafer thickness at the position in the radial direction is created. The thickness shape outputted by the measuring machine and a thickness shape outputted by the function are compared with each other, and an error on the entire surface of the wafer is confirmed to be not greater than a predetermined error. After the confirmation, information of the function for each angle is attached to the wafer as data representing the wafer shape and supplied to a user.

  • Patent number: 11802984
    Abstract: A method for improving a backpropagation-enabled process for identifying subsurface features from seismic data involves a model that has been trained with an initial set of training data. A target data set is used to compute a set of initial inferences on the target data set that are combined with the initial training data to define updated training data. The model is trained with the updated training data. Updated inferences on the target data set are then computed. A set of further-updated training data is defined by combining at least a portion of the initial set of training data and at least a portion of the target data and associated updated inferences. The set of further-updated training data is used to train the model. Further-updated inferences on the target data set are then computed and used to identify the occurrence of a user-selected subsurface feature in the target data set.
