This paper proposes a decision tree learner for data streams, the Hoeffding Tree algorithm, which comes with the guarantee that the learned decision tree is asymptotically nearly identical to that of a non-incremental learner using infinitely many examples. This work constitutes a significant step in developing methodology suitable for modern ‘big data’ challenges and has initiated a lot of follow-up research. The Hoeffding Tree algorithm has been covered in various textbooks and is available in several public domain tools, including the WEKA Data Mining platform.
A Stingray-style false GSM base station, hidden in a backpack; presumably they detect numbers in the vicinity, and SMS-spam those numbers with phishing messages. Reportedly the scammers used this trick in “Guangzhou, Zhuhai, Shenzhen, Changsha, Wuhan, Zhengzhou and other densely populated cities”. Dodgy machine translation:
