Binary Classifier
Apr 23,2009 Scott MitchellThis pattern is used to put information into ONE of TWO categories. When using this pattern, there is a source (or multiple sources) of information where each element in the source needs to be categorized. Each element in the source is analyzed and ultimately categorized as either Category A or Category B. Items may NOT be categorized as BOTH A and B. Items may not be categorized as NEITHER A nor B.

This pattern is used to put information into ONE of TWO categories. When using this pattern, there is a source (or multiple sources) of information where each element in the source needs to be categorized. Each element in the source is analyzed and ultimately categorized as either Category A or Category B. Items may NOT be categorized as BOTH A and B. Items may not be categorized as NEITHER A nor B.
Classification is typically driven by questions. For example:
- Is this an apple or an orange?
- Is this alive or dead?
- Is this important or not?
Classification can use a series of questions as well, but must result in either A or B. For example when sorting through old things trying to determine what to TOSS OUT or KEEP.
- Have I used this in the last 2 years?
- If yes, then will I continue to need to use in in the next 2 years?
- If yes, then KEEP
- If no, then is it replacable (see below)
- If no, then is it replaceable?
- If no, then am I willing to part with this item forever?
- If yes, then TOSS OUT
- If no, then KEEP
- If yes, then how expensive will it be to replace?
- If prohibitively expensive, then am I willing to part with this item (basically) forever?
- If yes, then TOSS OUT
- If no, then KEEP
- If inexpensive to replace, then TOSS OUT (you can but one later if you need it)
- If prohibitively expensive, then am I willing to part with this item (basically) forever?
- If no, then am I willing to part with this item forever?
- If yes, then will I continue to need to use in in the next 2 years?
REMEMBER: Ensure that there are only two categories. Avoid the false dilemma fallacy (also called false dichotomy and the either-or fallacy) where two categories are forced even though there are more than two categories.
