| Apr 3, 2015 at 7:32 | comment | added | Vladislavs Dovgalecs | Ok, how do you interpret the weight vector? Can you draw it? What will it define? | |
| Apr 3, 2015 at 7:31 | comment | added | Dr. Hoshang | more hint will be required ! I think the solution that mentioned by my book is wrong ! @xeon thanks | |
| Apr 3, 2015 at 7:29 | comment | added | Vladislavs Dovgalecs | Hint: What will be the boundary between the two classes? Linear, polynomial, something else? | |
| Apr 3, 2015 at 7:27 | comment | added | Dr. Hoshang | I means Fisher’s linear discriminant is given by the vector w which maximizes... it's noted on every material like as luthuli.cs.uiuc.edu/~daf/courses/Learning/Kernelpapers/… on p. 2. is it okey @xeon ? | |
| Apr 3, 2015 at 7:16 | comment | added | Vladislavs Dovgalecs | What is the definition of the Fisher criterion weight? | |
