  • Publication number: 20190385061
    Abstract: A computer-implemented method is provided for learning an action policy. The method includes obtaining, by a processor, environment dynamics including triplets of a state, an action, and a next state. The state in each of the triplets is an expert state. The method further includes training, by the processor using the environment dynamics as training data, a dynamics model which obtains a pair of the state and the action as an input and outputs, for each next state, state-transition probabilities. The method also includes learning, by the processor, the action policy using trajectories of expert states according to a supervised learning technique by back-propagating error gradients through the trained dynamics model.

  • Publication number: 20190259175
    Abstract: Methods and a system are provided for detecting object pose. A method includes training, by a processor, a first autoencoder (AE) to generate synthetic output images based on synthetic input images. The method further includes training, by the processor, a second AE to generate synthetic output images, similar to the synthetic output images generated by the first AE, based on real input images. The method also includes training, by the processor, a neural network (NN) to detect the object pose using the synthetic output images generated by the first and second AEs. The method additionally includes detecting and outputting, by the processor, a pose of an object in a real input test image by inputting the real input test image to the second AE to generate a synthetic image therefrom, and inputting the synthetic image to the NN to generate an NN output indicative of the pose of the object.

  • Publication number: 20190137954
    Abstract: A computer-implemented method executed by a robotic system for performing a positional search process in an assembly task is presented. The method includes decomposing, by the robotic system, a perturbation motion into a plurality of actions, the perturbation motion being a motion for an assembly position searched by the robotic system, each action of the plurality of actions related to a specific direction. The method further includes performing reinforcement learning by selecting an action among decomposed actions and assembly movement actions at each step of the positional search process based on corresponding force-torque data received from at least one sensor associated with the robotic system. The method also includes outputting a best action at each step for completion of the assembly task as a result of the reinforcement learning.

  • Patent number: 10237058
    Abstract: The present invention can be a method, system, and computer program product. One embodiment of the present invention provides a computer-implemented method for identifying an artificial object. The method includes receiving capacitance data which is obtained by measuring with at least one electrodes in a sensor at least one predefined surfaces of the artificial object placed against the sensor; converting each of the obtained capacitance data into an evaluation level in an evaluation system having more than two evaluation levels, to obtain a capacitance distribution on the surface of the artificial object; determining whether the obtained capacitance distribution matches a pre-registered capacitance distribution or one of pre-registered capacitance distributions; and if the determination result is positive, concluding the artificial object is identified.

  • Publication number: 20190078186
    Abstract: In order to improve the ductility or formability of a magnesium alloy, addition of rare earth elements or refinement of grain size is often used. However, conventional additional elements inhibit the action of grain boundary sliding for complementing plastic deformation. Therefore, it is required to search for additional elements that act to facilitate the grain boundary sliding not only at a conventional deformation speed but also in a higher speed range while maintaining a microstructure for activating non-basal dislocation. The present invention is to provide a wrought processed Mg-based alloy having excellent ductility at room temperature, which consists of 0.25 mass % or more to 9 mass % or less of Bi, and a balance of Mg and inevitable components, and is characterized by having an average grain size of an Mg parent phase after solution treatment and hot plastic working after casting of 20 ?m or less.

  • Patent number: 9857676
    Abstract: A system and method for optimizing (designing) a mask pattern, in which SMO and OPC are collaboratively used to exert a sufficient collaborative effect or are appropriately used in different manners. The method for designing a source and a mask for lithography includes a step (S1) of selecting a set of patterns; a step of performing source mask optimization (SMO) using the set of patterns, under an optical proximity correction (OPC) restriction rule which is used for selectively restricting shifting of an edge position of a polygon when OPC is applied to the set of patterns; and a step (S3, S4) of determining a layout of the mask for lithography, by applying OPC to all patterns constituting the mask for lithography using the source optimized through the SMO.

  • Patent number: 9395622
    Abstract: In one embodiment, a source mask optimization (SMO) method is provided that includes controlling bright region efficiency during at least one optical domain step. The bright region efficiency being the proportion of the total transmitted light that is transferred to bright areas of a target pattern. The optical domain intermediate solution provided by the at least one optical domain step may then be binarized to obtain an initial spatial domain solution with a controlled MEEF (Mask Error Enhancement Factor). The MEEF is controlled during at least one spatial domain step that optimizes the initial spatial domain solution.
