Mining Patterns and Trends in Data Stream

发布时间：2021-08-12 11:29

　　Living in the information age,today’s people mostly spend their time with gadgets to do（almost）everything,like dealing with the online transactions,updating social media status,commenting one’s status or company’s products,sharing pictures and videos,applying jobs via web based job search engines,etc.These phenomena make data hence also information are continuously being produced,streamed and received in a big volume and high velocity by（almost）every digital devices and censors over the entire g...
