Abstract: The technical solutions of the present disclosure are directed to providing validated responses to form specific user queries using machine learning. A system can include a processor to receive, via a user interface, a query corresponding to an entry of a form and identify a data structure. The processor can generate, using the data structure, a prompt to validate the entries and identify, based on the prompt and the data structure input a ML model, an error in an entry of the plurality of entries of the form. The processor can generate, based on the error and the data structure input into the ML model, a response to the query comprising a proposed correction to the error in the form, and provide, for display via the user interface, the response to the query indicating the error and the proposed correction.

Abstract: Described herein are devices and methods for generating new, lower-cost chloride solid electrolytes useful for lithium ion batteries. The devices replace higher cost, difficult to acquire elements such as Sc with less expensive, readily available elements such as Mg and Zr to form a highly conductive spinel structure. These materials may have a high ionic conductivity on the order of 0.23 mS/cm.

Abstract: This document describes systems and techniques that enable continuous personalization of face authentication. In aspects, an authentication system associated with a network includes an authentication manager. The authentication manager receives an embedding representing image data associated with a user's face. The authentication manager generates a confidence score based on the embedding. Further, the authentication manager updates previously enrolled embeddings with the embedding based on the confidence score, the embedding meeting a clustering confidence threshold. Through such a technique, the authentication manager can alter the previously enrolled embeddings by which a future embedding is used to authenticate the user's face. By so doing, the techniques may provide more-accurate and successful user authentication over time.
