Abstract: Embodiments provide methods, and systems for facilitating a payment transaction utilizing a pre-defined radio frequency allocated by an agency to a merchant. A user may open an application provided and maintained by a payment network on a user device and input the pre-defined radio frequency associated with the merchant. The payment network server is configured to establish a secure radio frequency connection between the user device and a merchant server of the merchant. Post establishment, the user may proceed to make a payment transaction to the merchant by choosing a payment method and authenticating his/her identity. The payment transaction is authorized by an issuer of the payment account and is forwarded to the payment network server. The payment network server is configured to fetch acquirer information of the merchant account and process the payment. Post completion, a confirmation message is sent to the user device over the secure RF connection.

Abstract: A video translation system that generates an output video in a target language which includes a translated/output audio track that runs in synchrony with the video content of a received input video in a source language and further displays translated subtitles corresponding to the translated audio track is disclosed. Upon receiving the input video, the domain of the input video can be identified. A translation engine and a transcription engine are selected based on the domain and the pair of languages corresponding to the input video and the output video. The output audio track is generated using the translation engine and merged with a manipulated video, which runs in synchrony with the output audio track to generate the output video. The transcription engine generates subtitles translated from the source language to the target language for the output video.

Abstract: This disclosure relates to methods, non-transitory computer readable media, and systems that asynchronously train a machine learning model across client devices that implement local versions of the model while preserving client data privacy. To train the model across devices, in some embodiments, the disclosed systems send global parameters for a global machine learning model from a server device to client devices. A subset of the client devices uses local machine learning models corresponding to the global model and client training data to modify the global parameters. Based on those modifications, the subset of client devices sends modified parameter indicators to the server device for the server device to use in adjusting the global parameters. By utilizing the modified parameter indicators (and not client training data), in certain implementations, the disclosed systems accurately train a machine learning model without exposing training data from the client device.

Abstract: Aspects of the present disclosure provide systems, methods, and computer-readable storage media that support automated account maintenance and fraud mitigation for secure accounts such as vendor master accounts or client master accounts. To illustrate, a system receives a request from a user to update an account. The system extracts request data from the request, for example using natural language processing and optical character recognition. The system performs validation operation(s) (e.g., entry validation, location validation, domain validation, etc.), in some implementations using one or more machine learning models. Upon successful validation, if the user is an authorized contact for the account, the system authenticates the request (e.g., via request of an authorization code) and updates the account.

Abstract: Systems and techniques are described herein for updating a machine learning model on edge servers. Local parameters of the machine learning model are updated at a plurality of edge servers using fresh data on the edge servers, rather than waiting for the data to reach a global server to update the machine learning model. Hence, latency is significantly reduced, making the systems and techniques described herein suitable for real-time services that support streaming data. Moreover, by updating global parameters of the machine learning model at a global server in a deterministic manner based on parameter updates from the edge servers, rather than by including randomization steps, global parameters of the converge quickly to their optimal values. The global parameters are sent from the global server to the plurality of edge servers at each iteration, thereby synchronizing the machine learning model on the edge servers.
