Abstract: A modular radio frequency (RF) device includes N base units, each including a differential segmented array (DSA) tile with a support board and a two-dimensional (2D) array of electrically conductive tapered projections disposed on the support board. Neighboring pairs of the electrically conductive tapered projections form RF pixels. The N DSA tiles are arranged to form an RF aperture. The N base units are programmed to switch the RF aperture between a first operating mode and a second operating mode. In the first operating mode, the N base units are operated as at least two independent subsets with each subset operating as an RF transmitter or receiver independently of the other subsets. In the second operating mode all N base units coherently combine as a single phased array RF transmitter or receiver.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for a high-performance and low-latency implementation of a wavelet-based image compression scheme. A processor may generate, in a single pass for each of a plurality of horizontal and vertical divisions of an image frame, a set of wavelet coefficients for the image frame based on a DWT. The processor may select a set of bits associated with the set of wavelet coefficients to remove based on an entropy coding process. The processor may serialize the set of wavelet coefficients, where the set of serialized wavelet coefficients do not include the set of bits. The processor may output, for a second device, a bitstream including the set of serialized wavelet coefficients.

Abstract: A device may receive a structured dataset, a feature of the structured dataset, and a protected categorical dimension of the structured dataset, and may stratify the structured dataset into subsets by filtering the structured dataset based on the protected categorical dimension. The device may apply a quantile transform to data of the subsets, associated with the feature, to generate transformed subsets, and may combine the transformed subsets to generate a final dataset. The device may generate a training dataset for a machine learning model based on the final dataset, and may train the machine learning model with the training dataset to generate a trained machine learning model.

Abstract: The present teaching relates to method, system, medium, and implementations for augmenting data via data crowd sourcing. Local data are acquired by one or more sensors deployed on a first device. Augmented data are obtained where such augmented data are generated based on the local data and remote data from at least one second device and are rendered on the first device.

Abstract: The present teaching relates to method, system, medium, and implementations for text processing. When a plurality of unstructured text strings are received, an input from a user for at least some of the plurality of unstructured text strings is received that identifies one or more structural elements. Training data are generated to include the plurality of unstructured text strings and the identified one or more structural elements associated with the at least some of the plurality of unstructured text strings. A conversion model is trained, via machine learning, based on the training data and one or more previously trained language models. The conversion model is for converting an input unstructured text string into a structured data record by identifying at least one structural data element from the raw unstructured text string.

Abstract: A system and method permit a user to browse and compare products of a merchant using information about a competitor. In one embodiment of the system and method, a page server serves a competitor electronic page to a customer browser which permits the user to select a competitor. The competitor electronic page includes a hyperlink having a manufacturer ID parameter, which hyperlink, when selected, issues a request to the page server for competitor product information. The request includes the manufacturer ID. Responsive to that request, the page server uses the manufacturer ID to form a query to present to a product database having competitive product information, manufacturer information, product information and associations between that information. A database engine processes the query and returns records satisfying the query. The records are used to construct a competitor product electronic page permitting a user to select a competitor product.
