  • Publication number: 20200065814
    Abstract: Methods and systems are presented for classifying a particular user account as a fraudulent user account by analyzing links between the user account and two or more known fraudulent user accounts collectively. Attributes of the particular user account are compared against attributes of a plurality of known fraudulent accounts to determine that the particular user account has shared attributes with a first known fraudulent account and a second known fraudulent account. The shared attributes with the first known fraudulent account and the second known fraudulent account are analyzed collectively to determine a risk level for the particular user account. The risk level may indicate a likelihood that the particular user account corresponds to a fraudulent account.

  • Patent number: 10527436
    Abstract: Systems and methods are provided for estimating an arrival time associated with a trip. The exemplary method receives trip information including an origin and a destination of the trip, and determines a route connecting the origin and the destination. The route includes a plurality of road segments. The method then receives transportation information associated with the road segments of the route and extracts global features and local features from the transportation information. Each global feature is indicative of characteristics involving at least two of the road segments, and each local feature is indicative of characteristics related to an individual one of the road segments. The method applies a machine learning model to estimate the arrival time, which includes a first neural network dedicated to process the global features and a second neural network dedicated to process the local features. The first neural network is distinct from the second neural network.

  • Publication number: 20200005195
    Abstract: Machine learning techniques are used in combination with graph data structures to perform automated classification of accounts. Graphs may be constructed using a seed node and then expanded outward to second-degree nodes and third-degree nodes that are connected to a seed user account node via direct interaction between the accounts. Characterization information regarding the interaction between accounts can be stored in the graph (e.g., quantity of interactions, types of interactions) as well as other metrics and metadata. A classifier, using random forest or another technique, may be trained using a number of different graphs that can then be used to reach a determination as to whether a user account falls into one particular category or another. These techniques can identify accounts that may be violating terms of service, committing a security violation, and/or performing illegal actions in a way that is not ascertainable from human analysis.
