  • Patent number: 9454573
    Abstract: A method and system for executing database queries in parallel using a shared metadata store. The metadata store may reside on a master node, and the master node may distribute this metadata with query plans to worker nodes. The worker nodes may request additional metadata from the master node when necessary.

  • Patent number: 9275347
    Abstract: Embodiments are directed towards online content classification that includes training a machine learning system. A batch of data items may be randomly selected from unlabeled test data. The batch of data items may be communicated to a client computer enabling a user to label each data item based on the contents of each data item. These labeled data items may be employed to train the machine learning system. While a classification result score is less than a threshold value, iteration may be performed to train the machine learning system. For each iteration another batch of data items may be selected from the unlabeled test data. This batch of data items may be classified using the machine learning system. The batch of classified data items may be communicated back to the client computer to be labeled by the user.

  • Patent number: 9189489
    Abstract: Inverse distribution operations are performed on a large distributed parallel database comprising a plurality of distributed data segments to determine a data value at a predetermined percentile of a sorted dataset formed on one segment. Data elements from across the segments may be first grouped, either by partitioning keys or by hashing, the groups are sorted into a predetermined order, and data values corresponding to the desired percentile are picked up at a row location of the corresponding data element of each group. For a global dataset that is spread across the database segments, a local sort of data elements is performed on each segment, and the data elements from the local sorts are streamed in overall sorted order to one segment to form the sorted dataset.

  • Publication number: 20150278309
    Abstract: A random number generation process generated uncorrelated random numbers from identical random number sequences on parallel processing database segments of an MPP database without communications between the segments by establishing a different starting position in the sequence on each segment using an identifier that is unique to each segment, query slice information and the number of segments. A master node dispatches a seed value to initialize the random number sequence generation on all segments, and dispatches the query slice information and information as to the number of segments, during a normal query plan dispatch process.

  • Publication number: 20110006922
    Abstract: The present invention provides a method for detecting the current location of a bus at lower cost without using a wideband wireless communication device and displaying it on each bus stop. A center system of a center and each of bus stop systems are coupled to each other via Internet. A roadside wireless unit of the bus stop system contained in the bus stop periodically outputs a beacon containing a bus stop ID to a route bus system equipped on a route bus. The route bus system outputs an ID notification signal including a bus stop ID and a bus ID to the bus stop system. The center system of the center updates location information using the bus stop ID and the bus ID and transmits bus location update data to a suitable target. The bus stop system displays a bus location thereon using the transmitted bus location update data.
