Assume P(C2) = eP(C1) (where e is the Euler number ln(e) = 1)
And i know P(C2) + P(C1) = 1
find P(C2) and P(C1)
Thanks.
Well there are Euler numbers and then there's Euler's number. Here you are asked about Euler's number which is just a constant (a real number with interesting properties). What are P(Ci) supposed to represent? I don't see why it's not just a system of equations.
a = eb
a + b = 1
Find a and b.
Ok thanks, the whole question
Consider a 2-class problem with two-dimensional features (x1,x2)transposed . The class conditional distributions P(x|Ci) are modelled by gaussian densities means = (-1,1) transposed and (1,1) transposed respectively with identical covariance matrices.
Assume P(C2) = eP(C1) (where e is the Euler number ln(e) = 1) and use the logistic discriminant fuction to derive the explicit expression of P(C1|x)
