Disadvantages of Rule-Based Systems (Part 1)

In Orwellian Event Processing the discussion moved away from my original intent, which was primarily to discuss the vendor-state-of-denial regarding the prior art for processing complex events, and gravitated toward a discussion on the “inefficiencies” of rule-based systems.  I was surprised learn that there are professionals who believe that there is no basis in fact [...]

Orwellian Event Processing

Recently we completed the installation and training of an open source Bayesian classifier to replace a rule-based approach to manage forum spam.  In a nutshell, we found the rule-based approach was highly prone to both false positives and false negatives; however, a statistical approach using a Bayesian approach has turned out to be far superior. [...]

A Hidden Danger in Cloud Computing

Back in the days when I was happily spending time on the operations floor in computing centers, we always observed that the greatest security threats to our systems were well-intended operators who make simple mistakes.  No hacker or criminal ever brought down a network like the bored network guy on the late shift who decided [...]

Processing Complex Events at the Large Hadron Collider (LHC)

Here is an excellent Google TechTalk by Dr. Majorie Shapiro (LBL & LHC ATLAS), June 18, 2007, on processing complex events at the LHC called, Supersymmetry, Extra Dimensions and the Origin of Mass: Exploring the Nature of the Universe Using PetaScale Data Analysis.
This is really what I would call “real-time CEP.”  Bean collisions at the [...]

Creative E-Trade and Similar Salami Scams - Ignorance is Bliss

Here is one of my favorite news stories of the week, Guilty Plea for Man Behind Creative E-Trade Scam.
In this funny story, Michael Largent, 23, of Plumas Lake, CA, wrote a simple  Internet script that opened more than 58,000 online accounts at places like E-trade and Schwab.   Largent used fake names to automatically open [...]

Real-Time, Online and Offline Complex Event Processing

Using NIST as computer science reference, an online algorithm is an algorithm that processes data (including events) element-by-element (and event-by-event), serially without having the entire problem space available from the beginning.  In contrast, an offline algorithm is provided the entire problem set from the start.
Hence, real-time event processing applications generally involve online processing.  Offline processing is useful when creating models [...]

Quintessential Event Processing: Signature Versus Anomaly Detection

Detection experts understand that the optimal detection design and architecture is generally a combination of both signature and anomaly detection engines.   In event processing, signature detection involves the real-time pattern matching analysis of events.   A core advantage of signature detection is that basic pattern matching models are easy to understand and develop [...]

Twenty Four CEP Public Presentations on SlideShare

For archiving purposes, I have uploaded 24 public CEP presentations that I presented over an 18 month period at various conferences from March 14, 2006 to September 21, 2007.  These presentations can be viewed here.  For example, my first public CEP presentation:

So far, I have placed [...]
