Introduction Example of Unstructured Data to Tensor Data Processing Education

Abstract

Big data includes data such as PDFs, audios, images, and videos, which are called unstructured data, and data scientists need to have the skills to process those data. This research aims at education on unstructured data processing of images and videos. Regarding tensor data processing, we have been developing tools and learning materials that are useful for learning it. Furthermore, we have been conducting education using them. This time, as an applied content of the education, we introduce the education of image / video processing using HOSVD, which is one of the tensor decomposition, into subjects of our advanced course and department. Therefore, this paper describes that case. As a result, it was found that students could generally perform the processing by applying HOSVD.
