Amazon.com just posted my four star review of Investigative Data Mining for Security and Criminal Detection. From the review:
"I read 'Investigative Data Mining for Security and Criminal Detection' (IDM) after attending the 2003 Recent Advances in Intrusion Detection (RAID) conference. Researchers at RAID mentioned "self-organizing maps," "neural networks," "machine learning," and other unfamiliar topics. Mena's book helped me understand these subjects in the context of performing data mining. If you steer clear of the author's discussion of intrusion detection in chapter 10, you'll find IDM enlightening and a little scary."
Data mining is a hot topic. Slashdot discussed neural networks recently, which can be used for data mining.
