R: Fuzzy Thinking in Smalltalk

Lorenzo

Hi Cedrick,

 

this version is an evolution of an application that I presented maybe at 3° or 4° ESUG held and promoted in Università Cattolica di Brescia, were I was professor of O.R.

After that, I implemented 3 or 4 new versions using some algorithms I created.

I have been very lucky becouse I found a real application in foot-ball major league in Italy and I undersood the importance this field.

Than, I added genetic algorithm to my implementation in order to optimize the application and (as I had experince in stock exchange field) I developed  the application I have sent to Richard.

If you are interested to the application, I should be pleased to share my experience with everyone could be interested, but only if we can SHARE our experiences and, possibly to create commercial application to be sold.

Anyway, if you want to work in this field, I will be happy to share my experience with you

 

Lorenzo

Even though the article is interesting, there is no mention of the word 'Pharo' anywhere in the article, nor in any of the 3 slide presentations. Nor is there any Pharo or even Smalltalk code to be seen.

 

 

It is interesting indeed and I also agree that at least, if we had some code to see, that would be ok to me, because people can decide to port eventually.

 

I’m interested in all tool that manage uncertainty. Instead of Fuzzy Logic, I chose The Transferable Belief Model [1] 10y ago, (a derivative of Dempster Shafer Theory). 

But this is probably different in essence, also it seems that it goes further that fuzzy logic since I see some genetic algorithms mentions. 

 

I’d be interested though to look and try your system (and eventually port it to pharo if the licence is MIT).  The term fuzzy world sounds nice to me.




It is very well possible that you have an application in Pharo, if so, I and everybody on this list would be *very* interesting is learning more about it.

 

Sure, also the thread was not easy to get. Do not take it personally, but mailing-list have to be friendly moderated ;-)

 

Is your code open source ?

 

 

Cheers,

 

Cédrick

In reply to this post by horrido
Hi Rich,

I share completely your opinion; ST is the real point; let's go on!

If you are interested, I have an application (MIDA - Management Integrato
Dati Aziendali) which first version has been HP official application for
companies in Italy.

Ciao package

Lorenzo

I see two major points here. First, that this forum is supposedly only for
Pharo-related matters (not general Smalltalk-related matters), and second,
that people want to see actual source code.

I think this is too narrow a viewpoint and here's why. First, the Pharo
Smalltalk Users forum is, as far as I can tell, the largest
Smalltalk-related forum in the world. This is a testament to the popularity
and power of Pharo.

So, if you want to reach the *largest Smalltalk audience*, this is
unquestionably the best forum to do so. We should not limit ourselves to
only Pharo-related matters; this doesn't help the broader Smalltalk
community.

There are many subscribers here who use other Smalltalks. They may come here
simply because the forum is so large. If the size of the Pharo forum was
insignificant, why would others bother to come here?

I've said this before: a rising tide lifts all boats. We should help each
other...Pharo, Squeak, VA Smalltalk, GemStone/S, etc. This is a great
community, so let's not sequester ourselves into cliques.

Of course, I'm not suggesting that Cincom users come here for user support.
Exercise good judgement here. But we can discuss Smalltalk topics of a more
general nature.

It's a two-way street: Pharo and other Smalltalks can cross-fertilize with
each other. That's why Lorenzo's article is so valuable.

Second, Lorenzo's article didn't show source code, but it did provide an
interesting backdrop. We can see the value of fuzzy logic and how Lorenzo
applied it. This may inspire others to follow up on this in whatever way
they deem appropriate. Maybe someone will implement fuzzy logic in Pharo!
That would be something.

I would like to believe that the Pharo community is a generous and gracious
one. That would help Smalltalkers everywhere. All for one and one for all.

Hi Lorenzo, 

Thanks for the explanation.

I’m an assistant professor, not really working in this field (it’s « only » a tool for me to model information with its inherent (epistemic) uncertainty). 

I’ll contact you offlist to discuss more on the subject, especially on the way you model you fuzzy subsets.

Cheers,

Cédrick
