Abstract: A method, apparatus and system for determining user-content associations for determining and providing user-preferred content using multimodal embeddings include creating an embedding space for multimodal content by creating a first modality vector representation of the multimodal content having a first modality, creating a second modality vector representation of the multimodal content having a second modality, creating a user vector representation, as a third modality, for each user associated with at least a portion of the multimodal content, and embedding the first and the second modality vector representations and the user vector representations in the common embedding space using at least a mixture of loss functions for each modality pair of the first, the at least second and the third modalities that pushes closer co-occurring pairs of multimodal content. Embodiments can further include generating content using determined attributes of a message to be conveyed and features of the user-preferred content.

Abstract: A computing system comprising a memory configured to store an artificial intelligence (AI) model and an image, and a computation engine executing one or more processors may be configured to perform the techniques for error-based explanations for AI behavior. The computation engine may execute the AI model to analyze the image to output a result. The AI model may, when analyzing the image to output the result, process, based on data indicative of the result, the image to assign an error score to each image feature extracted from the image, and obtain, based on the error scores, an error map. The AI model may next update, based on the error map and to obtain a first updated image, the image to visually indicate the error score assigned to each of the image features, and output one or more of the error scores, the error map, and the first updated image.

Abstract: In general, the disclosure describes various aspects of techniques for attention-based explanations for artificial intelligence behavior. A device comprising a memory and a computation engine executing a processor may be configured to perform the techniques. The memory may store the artificial intelligence model and the image. The computation engine may receive a query regarding the image, and execute the artificial intelligence model to analyze the image in order to output the result to the query. The artificial intelligence model may, when analyzing the image to output the result, segment the image into hierarchically arranged semantic areas in which objects in the image are segmented into parts, determine, based on the query, an attention mask for the areas, update, based on the attention mask, the image to visually identify which of the areas formed a basis for the result, and output the updated image.
