Abstract: Systems and methods for generating item recommendations from unstructured data using machine learning models are disclosed. One embodiment includes obtaining a dataset comprising a plurality of items, wherein each item includes at least one field containing unstructured data, preprocessing the dataset by performing filtering and text cleanup on the unstructured data, performing a coarse relatedness analysis by executing lookups on items in the dataset to identify potentially similar items and create links between items that are potentially interchangeable, performing coarse clustering by utilizing the links to organize related items into clusters using graph operations, performing fine clustering by constructing prompts for a large language model for each cluster to recluster items into subclusters and generate labels for canonical items and generating a list of interchangeable item recommendations based on the canonical items and their associated metadata.

Abstract: A fluid-dispensing unit in accordance with the present disclosure includes a fluid-storage can, a fluid-discharge controller, and a discharge unit coupled to the fluid-discharge controller. The fluid-storage can includes a container formed to include a fluid reservoir and a fluid discharger coupled to the container to communicate with the fluid reservoir in the container and allow pressurized fluid to exit the fluid-storage can in response to engagement of an actuator of the fluid-discharge controller. The discharge unit is configured to direct the exiting fluid through a spray path in response to engagement of the actuator.

Abstract: A collapsible air duct with inflatable insulative sleeve for supplying preconditioned air from a remote source to aircraft and similar vehicles. The system includes first annular interior chamber substantially surrounded by an a non-rigid inflatable sleeve which provides a thermal barrier from adverse environmental conditions. The non-rigid inflatable sleeve is filled by a portion of the air supply transiting the annular interior chamber through a series of perforations, thus providing an insulative air layer.
