Thanks for the video. Please, how can one optimise the coefficients of a Logistic Regression Model using a Genetic Algorithm?

Hi Sir , how can I plot the optimized variables x1, x2 and x3 according to the iterations? i.e. curve form is not a histogram?
@DEMFEA
@DEMFEA 2 года назад
Hi sir. If you need a curve, you may need to do optimization using MINITAB

Hi. May I know how to use ANN model as the objective function of GA and do maximization instead of minimization? I really need help, thank you in advance.

hi, I really liked your video. Your method is superb. I have a question. How can we optimize two equations simultaneously?
@DEMFEA
@DEMFEA 2 года назад
Thank you. I have never thought of this...but I think, the equations must be related to each other for optimisation to take place simultaneously. If they are not related (different variables and limits), you should optmise each equation differently if you are using GA. You can look into MINITAB and check if the software can do what you want.

Respected sir, I am new to this concept and want to optimize problems related to mechanical engineering..please it is very helpful if you reply to my query. I want to ask if the value of x, y, z are at three levels like lower, middle and upper level then how will we define the bound. or we will use the same process or different or it will automatically take the middle values. kindly clarify
@DEMFEA
@DEMFEA 2 года назад
If you have three variables with three levels, this is how you define your bounds: X=5 10 30 Y=7 30 45 Z= 1 3 7 Lb= [5 7 1] Ub=[30 45 7] We only take the lower and upper limits. The middle point is not relevant since it does not ‘bound’ the values The middle points will only be relevant when creating Design of Experiments

How to set upper bound as infinite
@DEMFEA
@DEMFEA 3 года назад
It is a bound, therefore it should be finite. In other words, infinite can be any number hence it cannot bound anything. I hope I have helped.
