Fuzzy Logic

Alex is settling in very nicely.  Definitely living up to the two major selling points of his breed (Sealyham Terrier) — "the couch potato of the terrier world" and "doesn't shed".  :)

And why a Sealyham Terrier?  Mostly, because Mr. Right was starting to fall for Bernese Mountain Dogs (they're really BIG and SHED LIKE CRAZY) and I figured I'd better make a more reasonable choice before the choice was made for me!  In principle, we believe in adopting from a shelter, but Mr. Right visited the shelter recently and they only had Pit Bulls.  Also... well...

Whatever, we're trying out the pure bred thing and Alex is a great one.  :)  Sealyham Terriers have become so rare they're considered an endangered breed, anyway, so perhaps he qualifies as some kind of rescue?  I don't know why they've fallen out of favor.  Very cute (unless groomed into ridiculousness) and such a charming disposition.  He's better than a cat.

Only failing so far — he shows no interest whatsoever in the graphs I painstakingly drew* of various methods for evaluating implication in fuzzy logic.

 

Cool, right?  Alex doesn't see it.  Mr. Right attempts to look interested, but I'm not quite believing it.

Any fuzzy logic enthusiasts in my audience?  Can you tell me why there are so many implication equations and why you'd choose one over the other?  Zadeh's Max Implication looks the most reasonable to me, coming from plain old classical logic, since it directly equates to "(not p) or (p and q)", but there has to be some reason for the others?

*Only to discover just after finishing them that I could have gotten them out of "Fuzzy Logic: A Modern Perspective" instead!  Honestly, I think it's a little ridiculous that none of other masses of writing I've waded through so far has had diagrams like this.  Pictures make things so clear!  People who want to convey information and increase understanding should use pictures.

A precious puppy and child photo. The post was comprehensible until halfway down. You have cousins that might comprehend your amazing graph, so perhaps they'll weigh in. I'm very impressed with its beauty. xoxoxoxo

My comprehension also got very fuzzy towards the end. Perhaps Alex appreciates fuzzy logic more than he lets on. He's a very quiet kind of dog.

A terrier as calm as a cat. Amazing! He sounds like the perfect dog for small children. I will send a link to your blog to Philip. He might comprehend your graph. xoxo

Don't know a thing about fuzzy logic but I know a lot about a particular pure-bred fuzzy dog -- Smoot, our bichon frise. He operates by frise logic, which has a special unanswerableness of its own that I bet your Alex would relate to! So cute!! Looking forward to reports of the interactions of Alex, Shmoogie and Mr Pants.
