In the 13:30 the correct value of y4 is 3, thank you for the great class.

[@Topperly]

Yes, it is. Apologies for the mistake and thank you for pointing it out! The correct value for y4 is 3 and the defuzzified value y* = 2.03

Thank you for this video, I badly needed to understand this

[@miltonganesh8680]

Thanks for clear explanation with an example.

[@Topperly]

Glad to hear that :)

[@raniermoura3825]

Very well explained!!

ma'am,which operator is used in takagi and sugeno approach..or (or) and??

[@Topperly]

Both (OR) and (AND) operator is used. If (OR) operator is used, take the maximum of the membership values of the two inputs and if (AND) operator is used, the minimum of the membership values of the two inputs should be considered. :)

Which implication and aggregation method did you use? Thank you.

[@Topperly]

Could you please provide the timestamp which you are referring to?

[@serhatozbey6872]

@@Topperly I've seen on the Mathworks website that the Sugeno method always uses prod for implication and sum for aggregation. For example, where did we perform the implication and aggregation process in the example in the 7th minute? Thanks.

What is advantage of Madani over Sugeno? Because it is difficult to obtain functions in Sugeno for me? So how I can validate that Madani is better than sugeno

[@muhammadshehbazaslam4549]

*mamdani

[@Topperly]

There's no apparent advantage of Mamdani over Sugeno. We use each method considering the application in hand and which suits the application better :)

[@demagovalla]

How do you find the function for y= f(x1, x2) for Sugeno Systems? For example why did you use 'y1 = (-x1) + x2 +1', Where does this come from? Please help :). And thank you for the amazing videos.

[@Topperly]

Incase of Sugeno systems, the equation will be given with the questions. Here the consequent is expressed in form of f(x,y), so the functions for each rule will be specified within the question. Generally for any Sugeno system, the equations are developed with the help of an expert who has years of experience in the system we are modeling. But with reference to the problems based on Sugeno, the functions will be provided along with the question. :)

Is it not a necessity that the total of all the membership values equals to 1 at any given point?

[@Topperly]

Hi Raihan, No... Membership values are not like probabilities :)

[@raihanmuhammad6689]

@@Topperly Thanks . I'll come back in 2 months to this video to say because of you I managed to finish my thesis 😊

[@harithobeid9521]

Thank you for the beautiful and interesting explanation, but I couldn't find the next video number (12,13,14,15,16) ,after defuzzification can u please give me the link .

Sugeno parameter estimation using LSE

[@Topperly]

Sorry, we didn't get you!

[@muhammadyezabaihaqi2215]

what are the r1 and r2?

[@Topperly]

r1 and r2 are constants. For instance, if you watch the example from 05:48, r in the Rule 1 is 1, r in the rules 2 is 3 and so on :)

[@muhammadyezabaihaqi2215]

I see, I have another question. How do we make the y? I am currently designing FLS using Sugeno but I confuse in making the y formula

[@Topperly]

Please watch lecture number 21 and 22 in our fuzzy logic playlist. It'll give you an insight :)
