  • Publication number: 20240322710
    Abstract: A control circuit for a multi-phase power conversion circuit and a multi-phase power supply are provided. The conversion circuit includes a plurality of switching circuits which have output terminals being coupled together to supply power to a load. The control circuit includes an error amplifier, a pulse width modulation circuit, and a multi-phase logic control circuit. The multi-phase logic control circuit generates a plurality of PWM signals according to an on time signal, which are delayed phase by phase and control on and off states of the plurality of switching circuits, and each of which has a pulse width being consistent with the on time signal. This reduces the circuit size and cost of the multi-phase power supply controller, and solves the problem of phase-to-phase current oscillation in a case that the switching circuits operate under duty ratios independent for various phases.

  • Patent number: 12099613
    Abstract: A method, computer program product, and computer system for repairing a Dockerfile. Library versions containing initial version numbers of libraries are extracted from the Dockerfile. A Monte Carlo tree search (MCTS) is executed, using the extracted library versions as input, which generates a tree that includes multiple levels populated with noses. Each node in a level represents the generic library name of a library version in the Dockrerfile and an associated randomly selected version number. At least one of the randomly selected version numbers associated with at least one node in a level differs from the initial version number associated with a versionf. A best successful installation path is selected from the at least one successful installation path. The Dockerfile is repaired by inserting randomly selected version numbers into Dockerfile as replacements for some of the initial version numbers.

  • Publication number: 20240312232
    Abstract: An embodiment for a method of extracting information from documents using knowledge graphs and prompt-based learning. The embodiment may receive a document and perform optical character recognition (OCR) to obtain OCR text lines and associated bounding boxes. The embodiment may encode each of the obtained OCR text lines into semantic vectors and each of the associated bounding boxes into position vectors to generate a knowledge graph using fusion vectors derived therefrom. The embodiment may receive a query including a key value. The embodiment may identify a series of candidate nodes including a series of most similar nearby nodes positioned near a first node associated with the key value. The embodiment may generate prompt template to determine closeness of the candidate nodes to the key value and calculate associated confidence levels. The embodiment may output extraction information associated with the candidate node having a highest calculated confidence level.

  • Publication number: 20240303365
    Abstract: Systems and methods are provided for privacy-preserving image feature matching in computer vision applications, including receiving a raw image descriptor, and perturbing the raw image descriptor using a subset selection mechanism to generate a perturbed descriptor set that includes the raw image descriptor and additional descriptors. Each descriptor in the perturbed descriptor set is replaced with its nearest neighbor in a predefined descriptor database to reduce the output domain size of the subset selection mechanism. Local differential privacy (LDP) protocols are employed to further perturb the descriptor set, ensuring formal privacy guarantees, and the perturbed descriptor set is matched against a second set of descriptors for image feature matching.

  • Patent number: 12068058
    Abstract: Embodiments of the present invention avoid the processing problems associated with using conventional computer systems for identifying and characterizing all of the substructures (e.g., metabolites) of large complex molecules by using a defined minimum cleavable unit (MCU) and an MCU graph for a chosen molecule, as well as a “cut vertex” in the MCU graph for the chosen molecule. The system splits the MCU graph of the chosen molecule at the specified cut vertex to produce two separate MCU graph components (i.e., a first MCU subgraph and a second MCU subgraph) of the chosen molecule, and generates and traverses a first line graph component and a second line graph component, respectively, for the two MCU subgraph components with a graph traversing algorithm to generate and store in memory a first database of substructures and molecular weights for the first component, and a second database of substructures and molecular weights for the second line graph component.

    Abstract: A database processing method and an apparatus are provided, and may be applied to a database system. A tree structure is used to represent a join order and used as an input of a neural network, and different first attribute matrices are allocated to different brother nodes in the input tree structure. This helps the neural network comprehensively learn information about the join order, obtain representation information capable of differentiating the join order from another join order, and predict costs of the join order accurately based on the obtained representation information of the join order. Then, an optimizer selects a join order with lowest costs for a query statement based on the costs predicted by a cost prediction module.

  • Publication number: 20240233665
    Abstract: Performing a three-dimensional (3D) reconstruction process of a set of selected image frames. In some instances, a plurality of sequential image frames that are extracted from a video file (including video content created through the use of Augmented Reality) are converted into a grayscale format. Once these image files are converted to a grayscale format, a two-dimensional (2D) entropy process is performed that is ultimately used to create a set of user-defined clusters, with each of these user-defined clusters being associated with at least a sub-set set of the grayscale frames. After a cluster is selected, a 3D reconstruction process is performed on the frames associated with the selected cluster.
