Latest Patents

Yoshitaka Ushiku holds a patent titled "Learning multimedia semantics from large-scale unstructured data." This patent describes systems and methods for learning topic models from unstructured data and applying these models to recognize semantics for new data items. In one embodiment, a corpus of multimedia data items associated with a set of labels is processed to generate a refined corpus. This processing involves arranging multimedia data items in clusters based on similarities of extracted multimedia features. The intra-cluster and inter-cluster features are utilized to remove multimedia data items from the corpus, resulting in a refined corpus that can be used for training topic models to identify labels. The resulting models are stored and can subsequently be used to identify the semantics of multimedia data items input by users.
