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 [...]

CEP as a Service (CEPaaS) with MapReduce on Amazon EC2 and Amazon S3

Posted on 11/25/08 1 Comment

Just as I was starting to worry that complex event processing community has been captured by RDBMS pirates off the coast of Somalia, I rediscovered a new core blackboard architecture component, Hadoop. Hadoop is a framework for building applications on large commodity clusters while transparently providing applications with both reliability and data motion.  Hadoop implements  [...]

The Motivation Behind Adaptive Analytics and CEP

Posted on 10/11/08 17 Comments

This is a continuation of The Genesis of Complex Event Processing: Asymmetric Capabilities and CEP, Event Noise and Asymmetric Event Processing where I have been discussing the motivation behind CEP and adaptive analytics in cyberspace. Around the same time that Professor Luckham and his team was working on CEP applications in network management and security [...]

TIBCO BusinessEvents 3.0

Posted on 09/24/08 11 Comments

I was pleased to read the Paul Vincent’s post, TIBCO BusinessEvents 3.0.    TIBCO has always had a forward thinking vision for distributed computing and this release of BE 3.0 is another step in the right direction.  TIBCO now has the only commercial-off-the-shelf (COTS) event processing platform on the market that supports distributed event processing, multi-agent [...]

On CEP as a Discipline

Posted on 08/05/08 No Comments

In  CEP as a Discipline,  David Luckham wrote:  “Actually, it is fair to say that some of CEP can be found in other disciplines. Event processing has been going on in one form or another, for the past 50 years. Simulation, Networking, Active DBs, Middleware. { …. } CEP has only just begun. The foundations [...]

Distributed Memory in Blackboard Systems

Posted on 07/26/08 2 Comments

Paul Vincent, ex-colleague at TIBCO, kindly responds to A Brief Introduction to Blackboard Architectures with Blackboards for Complex Event Processing. Paul correctly mentions that TIBCO’s BusinessEvents software is an excellent scheduling component in a blackboard systems architecture. However, I should briefly clarify Paul’s note that “blackboard systems historically used a single memory model (i.e. multiple [...]

A Brief Introduction to Blackboard Architectures

Posted on 07/20/08 4 Comments

A blackboard architecture is a distributed computing architecture where distributed applications, modelled as intelligent agents, share a common data structure called the “blackboard” and a scheduling/control process. The blackboard can be either centeralized or distributed, depending on the requirements and constraints of the application(s). To solve a complex problem in the blackboard-style, the intelligent agents [...]
