Abstract: In one embodiment, a method includes accessing a first document, accessing a plurality of second documents, calculating a relevance score for each of the plurality of second documents indicating a degree of relevance of the second document to the first document using an encoder of a machine-learning model, selecting a subset of the second documents based on their corresponding relevance scores, generating a target document by using the machine-learning model to process the subset of second documents and their corresponding relevance scores, and updating parameters of the machine-learning model based on a comparison between the first document and the generated target document.

Abstract: Methods, systems, and apparatuses for disguising or otherwise hiding big data access patterns and frequencies may include a replica being directly obtained from a key and a replica index, based on applying a pseudorandom permutation or pseudorandom function. Data object access frequencies may be quantized so that the ratios of quantized data object access frequencies are rational numbers of integers, which may allow for a uniform distribution of data object accesses. Fake accesses may be implemented by simulating an access schedule produced by a cryptographic primitive and by performing a greedy mapping between the real data object accesses and simulated data object accesses.

Finally, responsive to receiving the first user request, the object information of the target object may be stored in a multimodal dialog state.

Abstract: A user provides video data to an online system for presentation to additional users of the online system. Additionally, the user provides information to the online system identifying positions in the information capable of presenting supplemental content items, which may be sponsored, and may provide information describing a context of the video data at the various positions capable of presenting the supplemental content items. For example, the information identifies one or more times within the video data at which an advertisement is capable of being presented via the video data. Based on the information provided by the user, the online system selects supplemental content items for presentation via the video data at the identified positions and presents the selected supplemental content items to additional users viewing the video data at the identified positions.
