Abstract: Provided are a tab coating device. The tab coating device is configured to cover the insulating film on the end face of the tab of the tab coating device. It comprises a sleeve and a shaping piece. The sleeve is configured to be arranged on the outer peripheral surface of the electrode assembly in a sleeving mode. The shaping piece is configured to move along the axial direction of the sleeve and extend into the sleeve, to flatten the part of the insulating film that exceeds the end face of the tab onto the end face of the tab.

Abstract: In one embodiment, a method includes accessing, by a computing device, a natural-language input comprising a description of an avatar and generating, from the natural-language input and by a trained avatar-creation model, a set of avatar-attribute feature vectors. The method further includes determining, by a trained avatar-attribute classifier, one or more avatar attributes from the set of avatar-attribute feature vectors; and generating the avatar based on the determined one or more avatar attributes for presentation on a display of a computing device.

Abstract: Example computer-implemented methods and systems for fairness metric estimation are disclosed. One example method includes, for each user of multiple users, obtaining first data associated with a first collection of items, the first collection of items being recommended to the user by a recommendation model. Second data associated with a second collection of items recommended to the user is obtained, the second collection of items being randomly selected for recommendation to the user. A fairness metric is calculated as a calculated fairness metric and based on the first data and the second data.
