Abstract: A method including training predictor machine learning models (MLMs) using a first data set. The trained predictor MLMs are trained to predict classifications of data items in the first data set. The method also includes training confidence MLMs using second classifications, output by the trained predictor MLMs. The method also includes generating an aggregated ranked list of classes based on third classifications output by the trained predictor MLMs and second confidences output by the trained confidence MLMs. The method also includes training an ensemble confidence MLM using the aggregated ranked list of classes to generate a trained ensemble confidence MLM. The trained ensemble confidence MLM is trained to predict a corresponding selected classification for each corresponding data item in a training data set containing second data items similar to the first data items.

Abstract: A method involves scanning a symbol presented on a point of sale (POS) system including a POS processor; decoding the symbol to obtain purchase data and bidirectional connection data, where the bidirectional connection data describes a bidirectional connection; generating payment data using the purchase data; establishing the bidirectional connection with the POS system; sending the payment data to the POS system over the bidirectional connection; and receiving payment confirmation from the POS system over the bidirectional connection in response to the sending the payment data.

Abstract: A method, system, and non-transitory computer readable medium for removing noise ngrams from transaction records. The method may include obtaining noise ngrams; ordering the noise ngrams based on frequency of occurrence; discarding a portion of the noise ngrams below a frequency threshold to obtain a higher frequency subset of the noise ngrams; obtaining a transaction record of interest; and identifying a portion of the higher frequency subset within the transaction record of interest. Identifying the portion of the higher frequency subset may include constructing a regular expression based on the higher frequency subset; constructing a finite state machine based on the regular expression; providing the transaction record of interest as an input to the finite state machine; and executing the finite state machine. The method may also include removing, based on the identification, the portion of the higher frequency subset from the transaction record of interest.

Abstract: A non-transitory computer readable medium including instructions that, when executed by a processor, perform a method involving: receiving, by a point of sale (POS) system, purchase data for a customer; generating bidirectional connection data for the customer, where the bidirectional connection data describes a bidirectional connection; encoding a symbol with the purchase data and the bidirectional connection data; presenting the symbol to the customer; enabling the bidirectional connection in response to a connection request from the customer; receiving payment data from the customer over the bidirectional connection; comparing the payment data to the purchase data; and sending a payment confirmation to the customer over the bidirectional connection in response to a determination that the payment data satisfies the purchase data.

Abstract: A method for presenting a verified rental payment history of a rental user. The method includes selecting verified rental payment history factors related to a rental user's rental history and verified accounts of the rental user. The method further includes receiving authentication credentials for the verified accounts and receiving payment history records from the verified accounts using the authentication credentials. The method further includes generating renter analytics using the verified rental payment history factors and the payment history records. The method further includes generating the verified rental payment history using renter analytics and delivering the verified rental payment history to a landlord user.

Abstract: A method for processing payment is disclosed. The method includes obtaining, by a point-of-sale (POS) device from a certification authority, a certificate data item that identifies the POS device for completing a purchase by a consumer, generating a payment request containing the certificate data item, broadcasting the payment request via a wireless signal within a pre-determined range of the POS device for receiving by a mobile device of the consumer, where the mobile device stores payment credential of the consumer, receiving, by the POS device, an encrypted payment credential from the mobile device, where the encrypted payment credential is generated by the mobile device encrypting the payment credential based on the certificate data item, and decrypting the encrypted payment credential based on the certificate data item to retrieve the payment credential for processing the payment.

Abstract: A method and a system for wirelessly pairing a wireless peripheral with a computing or communication device and identifying a unique identifier of the wireless peripheral as an authorized wireless peripheral or the connected device owned by a user. The method and system further associate the wireless peripheral with the user, with the user's computing or communication device, or with an application installed on the user's device such that the computing or communication device wirelessly connects to the wireless peripheral for exchange of data or information by simply looking up the identifier of the wireless peripheral, without having to perform any wireless discovery protocols and user interaction or intervention for discovery or pairing of the computing or communication device and the wireless peripheral.

Abstract: The present invention provides a method and system suitable for managing the power consumption of a mobile communication device by way of a user-selectable profile. In response to receiving a power management-initiating signal the mobile communication device performs at least one of the following: Receipt of incoming communication is deferred while other functionality of the mobile communication device is retained; outgoing communication is grouped into a single transmission; and a subsequent transmission is deferred if the transmission requires power exceeding a predetermined threshold.

Abstract: Applications, methods and systems are defined that provide for network resources, such as Internet web sites or other networked sites, to be partitioned into multiple logically separable and typically independent information objects, referred to as derived content. The derived content will be defined by various attribute identifiers. The invention provides for storage and access of the derived content based on the attribute identifiers. In addition, the invention provides the ability to identify and extract changed versions of the derived content when the original network resource is altered.
