<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">I’m looking at the rules engine as a mechanism to find
patterns in some time series data.</span></font></p>
<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">I’m looking for things like there where N spikes above
a certain threshold value in a certain period of time.</span></font></p>

<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">I was wondering if anyone has done this, or have any ideas
on how best to do this with the rules engine.</span></font></p>

<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">My own ideas & the prototype I’ve built seem to be
really procedural, so I’m wondering if there’s a better way that I’m
missing.</span></font></p>
