    摘要: Methods, apparatus, and computer-readable media for determining and utilizing human corrections to robot actions. In some implementations, in response to determining a human correction of a robot action, a correction instance is generated that includes sensor data, captured by one or more sensors of the robot, that is relevant to the corrected action. The correction instance can further include determined incorrect parameter(s) utilized in performing the robot action and/or correction information that is based on the human correction. The correction instance can be utilized to generate training example(s) for training one or model(s), such as neural network model(s), corresponding to those used in determining the incorrect parameter(s). In various implementations, the training is based on correction instances from multiple robots. After a revised version of a model is generated, the revised version can thereafter be utilized by one or more of the multiple robots.

    摘要: A method for the computer-assisted control and/or regulation of a technical system is provided. The method includes two steps, namely learning the dynamics of a technical system using historical data based on a recurrent neuronal network, and the subsequent learning of an optimum regulation by coupling the recurrent neuronal network to another neuronal network. The method can be used with any technical system in order to control the system in an optimum computer-assisted manner. For example, the method can be used in the control of a gas turbine.

    摘要: A method for adjusting a compensator in a feedback control system for a coupled plant, derives a plurality of forward error values from position error signals that are sensed as outputs from the plant in response to a disturbance of the plant's operation. The position error signals are determined over plural, increasingly forward, time segments. A plurality of compensator output values are also determined over predetermined plural increasing forward, time segments. The derived forward error values are applied as inputs to the plant in a back propagation order, that order being in reverse time order to the time order in which the forward position error values were derived. Plural back propagation error values result in response to the back propagation application of the forward position error values. The back propagation error values are derived from within a portion of the compensator which has been configured as a Direct Form II filter function. The plural back propagation error values are then utilized in conjunction with the compensator output values and the forward position error values to derive altered compensator gain stage values to enable a reduction of the forward error values. To provide increased correction capability, the forward position error signals are altered by weighting functions before being employed as inputs to achieve the back propagation error values.

    摘要: A method for the computer-assisted control and/or regulation of a technical system is provided. The method is used to efficiently reduce a high-dimensional state space describing the technical system to a smaller dimension. The reduction of the state space is performed using an artificial recurrent neuronal network. In addition, the reduction of the state space enables conventional learning methods, which are only designed for small dimensions of state spaces, to be applied to complex technical systems with an initially large state space, wherein the conventional learning methods are performed in the reduced state space. The method can be used with any technical system, especially gas turbines.

    摘要: This invention includes the generation of forming information and its manipulation scheme as a method to form curved plates in ship hull-pieces. This invention consists of three components as follows: one is to construct and utilize a database which includes data about flat plates, objective curved plates, plates which are being formed, and their forming information, another is to infer new forming information with an artificial neural network system, and the third is to obtain forming information through calculating in-plane and bending strains. In the third, initial forming information is obtained by calculating strains from relationship between flat plates and objective curved plates. And new forming information is yielded through calculating the strains from relationship between partially formed curved plates and objective curved plates. Final objective plate are reached by repeatedly performing the measurement of the difference between plates in the proceeding steps and final objective plates and the calculation of the new strains in each process. Therefore, through this invention standardization and automation can be realized in the formation of curved plates.
