By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-New study results on computational int elligence have been published. According to news originating from Ibaraki, Japan,by NewsRx editors, the research stated, "In online shopping, user perspectives transit dynamically from abstract categories to concrete subcategories within a short period." Funders for this research include Japan Science And Technology Agency. The news reporters obtained a quote from the research from University of Tsukuba : "We propose a perspective-estimation system that estimates the dynamic, short- term perspectives of users by inferring a hierarchy of categories based on their actions. The proposed system analyzes the wish list rankings of users and their operational histories to extract the categories emphasized at that moment. It t hen employs formal concept analysis to infer the hierarchical structure of categ ories, thereby visualizing the dynamic short-term perspective. In experiments in volving 57 participants, the proposed method rates its match with user perspecti ves on a seven-point scale, achieving an average score of 4.84, outperforming th e feature estimation method using latent Dirichlet allocation (LDA), which score d 4.36."
