Disadvantages of Rule-Based Systems (Part 1)

Posted on 03/05/10 8 Comments

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 [...]

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.

Trend Prediction in Network Monitoring Systems

Posted on 03/04/09 19 Comments

Following up on Real-Time Predictive Analytics for Web Servers I thought we should “move up a level” and look at various open network monitoring platforms with trend prediction capabilities. Our web server management team picked Zabbix to monitor a busy production server and then we started to look into adding predictive analytics afterwards.   Alberto recommended [...]

Reasoning and Complexity

Posted on 02/25/09 No Comments

In a short follow-up to CEP Software Saves the Universe!, I thought it would be helpful to post some quotes from Wikipedia on reasoning and complexity. Cognitive science sees reasoning by the analogy to a data processing, where relations between observed properties of reasoning are used in numerous models leading to evident logically correct conclusions [...]

Situational awareness is a complex concept that cannot be accomplished by any of the “CEP” software on the market today.   In his post, Human CEP: the gut feeling?, Paul Vincent of TIBCO says, [A] firefighter avoiding death by analyzing his situation …. is provided by event-driven CEP systems. The fact of the matter is that [...]

Apache Mahout: Real-Time Decisioning in the MapReduce Framework

Posted on 01/14/09 2 Comments

Here is a bit of good news for the complex event processing space.  Folks on the Apache Mahout developers mailing list are showing an accelerated interest in topics related to real-time decision-making, starting with a Markov decision process. The Hidden Markov Model (HMM) is listed under “non map-reduce algorithms” on the Mahout wiki.  The developer’s [...]
