Good Explanation.
Pls check
1. The condition given for symmetry property of fuzzy relation , instead of mentioning they should be equal, it is given as they should be equal to 1
2. In the example, for transforming tolerance relation into equivalence relation
R2 = fuzzy max min composition of R1 and R is correct ( but it is shown as R1 o R1
Thank you Bhavani for pointing out the unforeseen mistakes.
To all viewers,
1. Please make note of point 1 she mentioned above. The definition given for symmetry of fuzzy relation at 11:30 is wrong. I made a mistake while preparing slides. The condition of symmetry is that diagonally opposite elements should be equal. This is correctly shown at 13:07 in the solved example.
2. The second mistake she pointed out is already corrected with a pop-up pointing out the mistake.
Apologies to everyone for these mistakes.
@@Topperly with regards to the first issue ... I think you meant "diagonally opposite elements should be EQUAL" .. and not equal to zero ... as mentioned in the original comment and in your video at 13:07 ...
still .. great work guys :))
I just discovered this channel. These videos are amazing. I realized that you have multiple playlists on different topics. I hope this channel gets more subscribers. Thank you for the effort sir
Thank you for your kind words :)
Amazing
Thank you :)
Nice explanation sir ❤
Glad you liked it :)
Sir , which composition method u used to get R . R in Fuzzy Relation ? max-min composition or max product composition ?
Hi,
I have used max-min method :)
Ok sir. Thank you so much 🙏 🙏
you have performed composition on crisp set on what basis ?
Hi Vaibhav,
Sorry, I didn't get the question. Could you please elaborate?
Hi @@Topperly
I meant is it min max or max product
It doesn't matter. As I have explained in previous video on compositions, for crisp sets, you'll get same results using max-min as well as max-product methods :)
