Strongly Regulate High Frequency Trading

In Regulation: Don’t Throw the Baby Out With the Bathwater, Progress CTO John Bates illustrates the principle of advocating a position based on a natural conflict-of-interest and then wrapping “the package” in rhetorical phrases.
First of all, the US economy (read individual investors) would be much better off if financial services firms (or anyone) were [...]

TIBCO Continues to Lead in the CEP Space

After months under the specter of civil unrest in Thailand, and more recently nearly a week dominated by a government imposed curfew in Thailand, I was pleased to read Paul Vincent’s post, TUCON2010: Reviewing the reviews, and yet more CEP presentations…” Paul, Alan and the TIBCO event processing team continue to demonstrate why TIBCO is [...]

RETE Engines Must Forward and Backward Chain?!

In a new development for me, I recently learned that one of the criteria for a “RETE-based rules-engine” to actually be classified as “RETE” is that the software must perform both forward and backward chaining. A well respected rules professional just informed me:
If [the rules-engine] is just forward chaining it’s not RETE because the [...]

Disadvantages of Rule-Based Systems (Part 1)

Events are important in business.
Events can be processed in a hierarchical way.
Rapide is a modeling tool developed at Stanford that can be used to model complex systems.

These three [...]

Well, after a long period of working on a number of operational projects, I’m going to take a break from writing code and actually do some blogging again. For some this is good news (and I quote from a private note):
I’m thankful you’ve started blogging again. For a while there I was afraid [...]

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.
