Abstract: Techniques for resolving brands in advertisement creatives include receiving one or more audio features and one or more video features, generating, based on the one or more video features, the one or more audio features, brand taxonomy data, and a brand alias table, and using a machine learning model, at least one of one or more resolved brands, a product category tree, or a chain-of-thought (CoT), and performing at least one action based on at least one of the one or more resolved brands, the product category tree, or the CoT.

Abstract: In various embodiments, a computer-implemented method for generating expiring user identifiers includes receiving an event-based identifier that uniquely identifies a user among a plurality of users, determining a time-to-live (TTL) based on the event-based identifier, generating a salt based on a current time and the TTL, providing, to a hash function, the event-based identifier and the salt to generate an expiring user identifier, and transmitting the expiring user identifier to at least one computing device to cause the at least one computing device, wherein the expiring user identifier obfuscates the event-based identifier from the at least one computing device and wherein a new expiring user identifier based on the event-based identifier has a same value as the expiring user identifier during at least a portion of the TTL.
