Mining High-Speed Data Streams: The Hoeffding Tree Algorithm
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.

Chinese scammers are now using Stingray tech to SMS-phish
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:
March 26, Zhengzhou police telecommunications fraud cases together, for the first time seized a small backpack can hide pseudo station equipment, and arrested two suspects. Yesterday, the police informed of this case, to remind the general public to pay attention to prevention. “I am the landlord, I changed number, please rent my wife hit the bank card, card number ×××, username ××.” Recently, Jiefang Road, Zhengzhou City Public Security Bureau police station received a number of cases for investigation brigade area of ??the masses police said, frequently received similar phone scam messages. Alarm, the police investigators to determine: the suspect may be in the vicinity of twenty-seven square, large-scale use of mobile pseudo-base release fraudulent information. […] Yesterday afternoon, the Jiefang Road police station, the reporter saw the portable pseudo-base is made up of two batteries, a set-top box the size of the antenna box and a chassis, as well as a pocket computer composed together at most 5 kg.
