Abstract: The disclosure addresses problems associated with a systematic integration of multi-modal data for effective training, and handling of large volume of data because of high resolution of the multiple modalities. Embodiments herein provide a method and a system for a distributed training of a multi-modal data fusion transformer. Herein, a distributed training approach called a Distributed Architecture for Fusion-Transformer Training Acceleration (DAFTA) is proposed for processing large multimodal remote sensing data. DAFTA is enabled to handle any combination of remote sensing modalities. Additionally, similarity of feature space is leveraged to optimize the training process and to achieve the training with reduced data set which is equivalent to a complete data set. The proposed approach provides a systematic and efficient method for managing large sensing data and enables accurate and timely insights for various applications.

Abstract: Existing approaches for switching between different hardware accelerators in a heterogeneous accelerator approach have the disadvantage that complete potential of the heterogeneous hardware accelerators do not get used as the switching relies on load on the accelerators or a random switching in which entire task gets reassigned to a different hardware accelerator. The disclosure herein generally relates to data model training, and, more particularly, to a method and system for data model training using heterogeneous hardware accelerators. In this approach, the system switches between hardware accelerators when a measured accuracy of the data model after any epoch is below a threshold of accuracy.

Abstract: State of the art methods require size of DL model, or its gradients be less than maximum data item size of storage used as a communication channel for model training with serverless platform. Embodiments of the present disclosure provide method and system for training large DL models via serverless architecture using communication channel when the gradients are larger than maximum size of one data item allowed by the channel. Gradients that are generated by each worker during current training instance, are chunked into segments and stored in the communication channel. Corresponding segments of each worker are aggregated by aggregators and stored back. Each of the aggregated corresponding segments are read by each worker to generate an aggregated model to be used during successive training instance. Optimization techniques are used for reading-from and writing-to the channel resulting in significant improvement in performance and cost of training.

Abstract: Systems and methods are provided for secure offline transactions using a mobile device. The mobile device may include an encrypted data store in which encrypted payment processing data is stored, a risk assessment engine configured to retrieve the encrypted payment processing data and determine, based on the encrypted payment processing data, whether an offline payment is authorized, and a transaction pool configured to store the offline payment after the offline payment has been provided to a recipient. The mobile device may provide the offline payment that has been performed to a payment provider server for completion and/or funding when the mobile device obtains a network connection to the payment provider server following the offline payment.

Abstract: When a user is requested to provide the user's social security number (SSN) or other personal information for conducting a credit/background check, the user may use a mobile app on the user's mobile device to display a unique identifier which is used in place of the SSN for processing the user's credit/risk analysis. The unique identifier is used as a protection layer on top of a user's SSN to reduce chances of identity fraud. In particular, an unique identifier (token) may be generated and issued to current payment account holders or new payment account holders when they sign up for payment accounts. When a merchant requires a customer's social security number for performing a credit or background check on the customer, the customer may simply provide the unique identifier and may be cleared to start using the merchant service without exposing the customer's SSN.

Abstract: A communication system transmitter comprises an adaptive error correction encoder. The adaptive error correction encoder is configured to generate a plurality of error correction frames with each such error correction frame comprising a plurality of data packets and one or more error correction packets. A given one of the error correction packets comprises information relating to the plurality of data packets of its corresponding frame and additional information relating to a different one of the error correction frames. The additional information may be inserted into a header of the given error correction packet, and may comprise a next frame sequence number indicator and a corresponding next frame mask value for a subsequent one of the error correction frames. Other aspects of the invention relate to a communication system receiver comprising an adaptive FEC decoder, adaptive FEC encoding and decoding methods, integrated circuits, and associated computer program products.

Abstract: In one aspect, a communication system transmitter comprises an adaptive error correction encoder. The adaptive error correction encoder is configured to generate a plurality of error correction frames with each such error correction frame comprising a plurality of data packets and one or more error correction packets. A given one of the error correction packets comprises information relating to the plurality of data packets of its corresponding frame and additional information relating to a different one of the error correction frames. For example, the additional information relating to the different one of the error correction frames may be inserted into a header of the given error correction packet, and may comprise a next frame sequence number indicator and a corresponding next frame mask value for a subsequent one of the error correction frames.

Abstract: An attacker is prevented from obtaining information about the configuration of a computer system. Each of one or more revealing content elements that may be found in outgoing data transmitted by the computer system and that are capable of being used by the attacker to obtain the information about the configuration of the computer system is associated with one or more respective replacement content elements. Outgoing data to be transmitted by the computer system are then scanned for these one or more revealing content elements. A revealing content element found in the outgoing data is replaced by a replacement content element from the one or more replacement content elements associated with that revealing content element. This is done before the outgoing data is transmitted.

Abstract: A method and system for reducing channel changing time in multicast media, that can include the steps of receiving at least one of a plurality of available channels from a service provider at a residential gateway through a network, ranking the popularity of at least one of the available channels at a ranking engine connected to the residential gateway, and requesting to receive a number of the channels available from the service provider at the residential gateway based on the ranking. The rank is at least partly based on the data stored in the database.
