  • Publication number: 20200242610
    Abstract: This application relates to apparatus and methods for identifying fraudulent transactions. A computing device receives return data identifying the return of at least one item. The computing device obtains modified strategy data identifying at least one rule of a modified strategy. The rule may be based on the application of at least one discrete stochastic gradient descent algorithm to an initial strategy. The computing device applies the modified strategy to the received return data identifying the return of the at least one item, and determines whether the return of the at least one item is fraudulent based on the application of the modified strategy. The computing device generates fraud data identifying whether the return of the at least one item is fraudulent based on the determination, and may transmit the fraud data to another computing device to indicate whether the return is fraudulent.

The computing device obtains modified strategy data identifying at least one rule of a modified strategy. The rule may be based on the application of at least one dimensionality reduction algorithm to an initial strategy. The computing device applies the modified strategy to the received return data identifying the return of the at least one item, and determines whether the return of the at least one item is fraudulent based on the application of the modified strategy. The computing device generates fraud data identifying whether the return of the at least one item is fraudulent based on the determination, and may transmit the fraud data to another computing device to indicate whether the return is fraudulent.

  • Publication number: 20200242673
    Abstract: This application relates to apparatus and methods for identifying anomalies within a time series. In some examples, a computing device receives sales data identifying a sale of at least one item, and aggregates the received data in a database. The computing device may generate a plurality of time series based on the aggregated sales data. The computing device may extract features from the plurality of time series, and generate an alerting algorithm that is based on clusters of the extracted features. The computing device may apply the alerting algorithm to a time series generated from received sales data to determine whether the time series is an anomaly. Based on the determination, the computing device may generate and transmit anomaly data identifying whether the time series is an anomaly, such as to another computing device.

  • Patent number: 10713538
    Abstract: Aspects of the present disclosure involve a system and method for learning from images of raw data, including transactional data. In one embodiment, a system is introduced that can learn from the images of such data. In particular, machine learning is implemented on images in order to classify information in a more accurate manner. The images are created from raw data deriving from data sources relating to user accounts, in various embodiments.

  • Publication number: 20190247030
    Abstract: Improved systems and methods for collecting, isolating and analyzing trophoblasts from the endocervical canal for prenatal genetic testing are disclosed. Particularly, an endocervical sample collection device is disclosed, where that collection device is enhanced with surface nanostructures/microstructures and functionalized with trophoblast specific antibodies to allow the collection device to preferentially adhere to and pick up fetal trophoblasts as opposed to maternal cells and/or non-cellular materials such as endocervical mucus. In addition, a non-caustic mucolytic preparation for treating endocervical sample to remove mucus while keeping the trophoblast cells intact and viable for downstream culturing and processing is disclosed.
