Abstract: Discussed herein are devices, systems, and methods for classification using a clustering autoencoder. A method can include obtaining content to be classified by the DNN classifier, and operating the DNN classifier to determine a classification of the received content, the DNN classifier including a clustering classification layer that clusters based on a latent feature vector representation of the content, the classification corresponding to one or more clusters that are closest to the latent feature vector providing the classification and a corresponding confidence.

Abstract: Techniques for multi-factor pathfinding are disclosed. A system receives multiple data sets that represent multiple physical properties associated with multiple three-dimensional coordinates of a physical environment. The system generates multiple weighted data layers corresponding to the physical properties, at least by applying weights to the data sets. The system generates a multi-factor costmap for the three-dimensional environment, based at least on the weighted data layers. The system determines a path through the three-dimensional environment, based at least on the multi-factor costmap.

Abstract: Subject matter regards improving machine learning techniques using informed pseudolabels. A method can include receiving previously assigned labels indicating an expected classification for data, the labels having a specified uncertainty, generating respective pseudolabels for the data based on the previously assigned labels, the data, a class vector determined by an ML model, and a noise model indicating, based on the specified uncertainty, a likelihood of the previously assigned label given the class, and substituting the pseudolabels for the previously assigned labels in a next epoch of training the ML model.

Abstract: A rotary blade includes a blade tip assembly with a first bus bar segment and a main blade assembly with second bus bar segment. The first bus bar segment is connected to the blade tip assembly and the second bus bar segment is connected to the main blade assembly. The blade tip assembly is connected to the main blade assembly such that the first and second bus bar segments are longitudinally offset from one another. A low-profile interconnect spans the first and second bus bar segments for resistively generating less heat than the bus bar segments for a predetermined current flow.

Abstract: An ice protection system (40) comprising electrothermal devices (41-44) having zones (41P-44P, 41L-44L, 41S-44S, 41T-44T) associated with respective surface regions of rotor blades. Each zone involves electric load (R) which converts supplied electrical power from one phase of a three-phase power system into heat. The combined load of the A-phase zones, the combined load of the B-phase zones, and the combined load of the C-phase zones are approximately equal.

Abstract: A refrigerated liquid dispensing system includes a cabinet having a refrigerated compartment. At least one liquid container such as a water bottle is mounted in a receptacle in the compartment. A valve is mounted to the neck of the bottle for controlling the flow of liquid from the bottle. In one practice of the invention the valve is actuated by a spring plunger mounted to the door of the compartment so that the valve can be actuated without opening the door to dispense water from a valve stem into a cup in a cup holder area below the compartment. In a further practice of the invention the valve is actuated by opening the door and acting directly on the valve. When the door opens a valve extension automatically slides outwardly so that a dispensing opening in the valve extension is disposed against a cup in the cup holder area.
