Models and Reductionism - Reducing Clouds Into Streams

Reducing complex problems sets to simple problem sets is an interesting, and sometimes valid, approach to complex event processing.    Transformations can be useful, especially when well defined.
For example, CEP was envisioned as a new technology to debug relatively large distributed systems, discover hidden causal relationships in seemingly disconnected event space.    This “discovery” requires backwards chaining with uncertainty, [...]

Implementing the Event Cloud

In his post, Cloudy Thinking, Marc Adler asks how to implement the event cloud.
As a reminder, we process event clouds; we don’t implement them.   Event clouds simply exist, independent of our desire to process and extract meaningful information from the event cloud.
For example, there are many voices in a crowded stadium.  These voices make up the “sound [...]
