I’m trying to create a fuzzy logic in Swi prolog for obtain the % of having COVID, based on number of symptoms, number of contacts and strict contacts. I’m also working with an ontology, so I’m taking data from there (so I know the number of symp,contacts and strict contatcs a Patient has). I tried …

I was hoping somebody who knew something about fuzzy logic would step up, but that hasn’t happened yet, so here’s an uninformed perspective. As far as I’m aware, neither (SWI-)Prolog or library(clpfd)natively support the notion of fuzzy logic so you’re going to have to provide more information on w…

Hi, thank you for your replying! I read it but didn’t find something for my project. Summarising my project, I want that when I ask "find_prob(Patient, P) it gives me something like P=0.7 (70% to have covid). Based on number of symptoms, number of contacts and strict contacts. I did this just using …

[image] MrAlex: I read it but didn’t find something for my project. I suggest you read it again; skip the theory and start with section 3. The fuzzy logic Prolog library appears to allow you to specify facts with a probability “interval” between 0 and 1 (which could be a single value in the r…

Thank you again. I tried my code on Ciao prolog, but once again I have a lot of errors (same happened with Bousi), it only works on Swi prolog. It seems I can only use CLP, since the fuzzy logic library does not exist in Swi prolog. Also, when I try to run those example on Swi prolog (the ones expl…

Yep true, but they give me so many errors that I should write them all xD. But the common thing, is that they don’t recognise some predicates that I have used for my program (Swi prolog does) or they have problems on how I have structured the program. So my question is how I can create a fuzzy mode…

I wonder whether you are talking fuzzy logic or probabilistic logic. What you are trying to do might be related to the work of @friguzzi and his team. You find the demos at http://cplint.ml.unife.it/

It’s a project I have for my university, where they asked me to use fuzzy logic for obtaining the final result. Btw I don’t know how to apply it, also cuz from my dataset I have the specific number of my variables , so it doesn’t seem so fuzzy

You don’t need constraint programming for fuzzy logic. Are talking about the same thing ? You need basic logic and math for fuzzy logic as far as I understand.
