Graphs have been widely used to represent complex data in many applications,
such as e-commerce, social networks, and bioinformatics. Efficient and effective
analysis of graph data is important for graph-based applications. However, most
graph analysis tasks are combinatorial optimization (CO) problems, which are
NP-hard. Recent studies have focused a lot on the potential of using machine

Abstract This paper explores the challenges raised by big data in
privacy-preserving data management. First, we examine the conflicts raised by
big data with respect to preexisting concepts of private data management, such
as consent, purpose limitation, transparency and individual rights of access,
rectification and erasure. Anonymization appears as the best tool to mitigate
such conflicts, and i... hiện toàn bộ

AbstractDiabetic eye disease (DED) is a cluster of eye problem that affects
diabetic patients. Identifying DED is a crucial activity in retinal fundus
images because early diagnosis and treatment can eventually minimize the risk of
visual impairment. The retinal fundus image plays a significant role in early
DED classification and identification. An accurate diagnostic model’s
development using a ... hiện toàn bộ
AbstractReview helpfulness prediction aims to prioritize online reviews by
quality. Existing methods largely combine review texts and star ratings for
helpfulness prediction. However, star ratings are used in a way that has either
little representation capacity or limited interaction with review texts. As a
result, rating information has yet to be fully exploited during the combination.
