Orwellian Event Processing

Posted on 02/28/10 16 Comments

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 US Constitutional Failure Regarding Our Protection

Posted on 01/01/10 No Comments

Like most of you, I am still in complete shock over Northwest Flight 253 and how our government still cannot connect-the-dots in simple intelligence matters to protect us from harm. In this case, the well-respected father of a radical-Islamic Nigerian named Umar Farouk Abdulmutallab reached out to the US Embassy and other organizations in an [...]

Processing Complex Events at the Large Hadron Collider (LHC)

Posted on 06/10/09 4 Comments

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 [...]

A Review of Zabbix – Zabbix Rules! (Part 2)

Posted on 03/23/09 2 Comments

In A Review of Zabbix – Zabbix Rules! (Part 1) we provided a brief introduction to Zabbix in the context of network and security management.  In this post I will discuss Zabbix as an event processing platform. Zabbix is like most event processing platforms.  Zabbix provides both agent-initiated events as well as server-requested events.  In [...]

Peter Lin on Situational Awareness and CEP

Posted on 03/01/09 14 Comments

Recently Peter Lin was kind enough to stop by and post this comment to our post, CEP Software Saves the Universe! Here’s my [Peter Lin's] bias perspective as a user and developer of expert system shell[s]. A business rule engine, expert system shell or CEP engine at best provide[s] a foundation for creating an expert [...]

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 [...]

CEP Software Saves the Universe!

Posted on 02/25/09 8 Comments

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 [...]

Classification in Complex Event Processing

Posted on 02/01/09 2 Comments

Following up on the excellent discussion in Predicting Events with Logistic Regression I think it is time to talk a bit about the importance of classification in complex event processing.  CEP is, by definition, about detecting business opportunities and threats in real-time.   It follows, that by definition, CEP is centered around classifying and discriminating complex [...]

Lessons Learned from High Tower’s Demise

Posted on 01/09/09 3 Comments

In November 2008, Aliso Viejo-based High Tower Software, a venture-backed developer of security, compliance, and log management software, shut down.   Like many of our “CEP/ESP vendors”, High Tower orchestrated numerous “awards” for their security information and event management (SIEM) software, However, these fluffy marketing awards were not enough to keep HT from a nose dive. [...]

Complex Systems and CEP

Posted on 11/30/08 1 Comment

A complex system is defined as a system composed of related components that as a whole exhibit one or more properties not obvious from the easily observed properties of the individual parts.  This is certainly true of the CEP notion of the “event cloud” in network systems.   A modern energy or telecommunications network is [...]
