Abstract: Techniques are disclosed for prompt-based few-shot entity extraction. The techniques include obtaining an annotated natural language document set for an arbitrary new entity type. A prompt sequence set is generated based on the annotated document set. A pre-trained entity extraction model is trained based on the prompt sequence set to yield a few-shot trained entity extraction model trained to extract at least the arbitrary new entity type. In response to obtaining a test document set, one or more entities of the arbitrary new entity type are extracted from the test document set using the few-shot trained entity extraction model.

Abstract: A system for determining store segments and store space allocation may include at least one computing device that is configured to obtain store sales data for each store in a group of stores and to determine a store segmentation score using a non-Euclidean distance metric characterizing a distance between a pair of stores in the group of stores. The computing device may also be configured to assign each store to a store segment based on the store segmentation score and validate a divergence of each pair of store segments using a divergence score metric.

Abstract: A gateway apparatus supports differentiated secure communications among heterogeneous electronic devices. A communication port communicates via communication networks of different types with two or more associated devices having diverse secure communication capabilities. The gateway logic selectively authenticates the associated devices for group membership into a Secure Communication Group (SCG), and selectively communicates Secure Communication Group Keys (SCGKs) to the devices having the diverse secure communication capabilities for selectively generating session keys locally by the associated devices for mutual secure communication in accordance with the group membership of the associated devices in the SCG.

Abstract: A system authenticates in-vehicle electronic devices having unequal capabilities such as having varying different communication and processing capabilities. A Connected Vehicle Gateway portion of a selected in-vehicle device acts as an onboard authentication proxy and onboard key server functionality for other in-vehicle devices, and serves as an interface between an in-vehicle network and one or more associated external networks, thereby eliminating the need for explicit peer discovery protocol and the requirement of devices to perform key establishment with each individual communication peer. Instead, each in-vehicle device establishes the group keys as a result of its authentication with the onboard key server and uses the group keys to locally generate and update its session keys. The onboard key server selectively obtains the keys from one or more off-board authentication servers and distributes them to selected in-vehicle devices.
