Weka discitization filter

sa afef
Hi , i use the antminer+ algorithm which use discritization method using Weka and in the decision list tha i have got this 

Ea >= '(96.35-inf)' => normal
amplitudemin >= '(-185.7-inf)' AND ecarttype <= '(-inf-59.35]' AND Ed2 <= '(-inf-19.95]' => normal
amplitudemax >= '(200.4-inf)' AND ecarttype <= '(-inf-59.35]' AND Ed2 <= '(-inf-19.95]' => normal
ELSE => abnormal


And i don't know how to read this i mean for example this Ea >= '(96.35-inf)' .What does it mean?
Thanks

It looks like antminer+ is treating the discretized attribute values as ordinal, which makes sense. The intervals obviously exhibit an order, so comparisons like >= or <= can be performed.

> Ea >= '(96.35-inf)'

would apply to any value of Ea greater than 96.35. "inf" stands for positive infinity.

Note that I don't know anything about antminer+ so the above interpretation might be wrong.

Cheers,
Eibe

Yes acttually it's true  antminer+  treat the discretized attribute values as ordinal and i just want to know the meaning of " -inf" and "+inf" in this intervals
thanks
