  • Publication number: 20210065187
    Abstract: Methods and systems for detecting fraudulent data points in a database of a computerized system include receiving, from a user interface, a request for detecting one or more fraudulent data points, choosing minimum and maximum values of k for use in clustering the data points in the database, k being a cluster number; and generating empty outlier scores corresponding to the data points. The methods and systems further include executing, starting with the minimum value of k, functions in an iterative or recursive manner, until the maximum value of k is reached. The functions include choosing k random points as centroids, performing k-means clustering on the chosen centroids, and computing a temporary outlier score for each of the data points in an iterative or recursive manner until a total number of data points is reached. The functions further include updating the outlier scores by adding the temporary outlier scores to the corresponding outlier scores and storing the updated outlier scores.

  • Publication number: 20210065208
    Abstract: Methods and systems for detecting fraudulent data points in a database of a computerized system include receiving, from a user device, a request for detecting one or more fraudulent data points in a database storing data points representing electronic transactions. The system constructs a feature vector fore each data point and k random vectors. After constructions, the system performs a combination of Locality Sensitive Hashing algorithm and Local Outlier Factor (LOF) algorithm on the constructed feature vectors and the constructed k random vectors to compute outlier scores for each data point. The system detects a fraudulent data point based on the outlier scores that indicate consistent degrees.

  • Patent number: 10704350
    Abstract: A process for drilling natural gas hydrates. A drilling rig is placed in seawater. A suction-press core drilling mode is adopted in a soft sediment formation, a suction-rotary core drilling mode is adopted in a medium-hard sediment formation, or a pumping direction circle-rotary core drilling mode is adopted in a hard sediment formation. A core is extracted. An inner tube for wireline pressure coring is recovered. A holding seal cap is tightened, and the inner tube is stored in a pipe storage rack. Punching is carried out. An inner tube for wireline pressure coring which is hollow is captured to disengage the holding seal cap. The inner tube is lowered. A drill rod is added. The punching is carried out again. The above steps are repeated until the core drilling reaches a given drilling depth. The drill rod, the drill and the corer are recovered.
