Abstract: A content analysis system provides content understanding for a content item using an attention aware multi-modal model. Given a content item, feature extractors extract features from content components of the content item in which the content components comprise multiple modalities. A cross-modal attention encoder of the attention aware multi-modal model generates an embedding of the content item using features extracted from the content components. A decoder of the attention aware multi-modal model generates an action-reason statement using the embedding of the content item from the cross-modal attention encoder.

Abstract: The disclosure relates to an offline-online question answering system. In some aspects, the techniques described herein relate to a method including: receiving, by a processor, a query from a user; generating, by the processor, a query embedding representing the query; identifying, by the processor, at least one question corresponding to the query by comparing the query embedding to a plurality of embeddings of questions; and transmitting, by the processor, an answer corresponding to the at least one question to the user in response to the query.

Abstract: A method for manufacturing a mechanical part by hot stamping, and a mold and a system thereof. The method includes: heating a steel plate blank at a predetermined heating temperature; and placing the steel plate blank into a mold of the mechanical part, and stamping the steel plate blank to form wrinkles at a rounded corner of the mold and form the mechanical part in the mold: wherein, the mold of the mechanical part includes a female mold and a male mold, a stamping gap configured to accommodate the steel plate blank is provided between the female mold and the male mold, and a width of the stamping gap at the rounded corner of the mold is larger than a thickness of the wrinkles.
