### Deriving of optimal decision boundary of two Gaussians

Given two Gaussians with the same variance $\sigma$ and means $\mu_1$ and $\mu_2$, where each Gaussian represents a class $C_1$ and $C_2$ with the same prior probabilities, i.e. $p(C_1) = p_(C_2)$, we ...

### Likelihood ratio test between two hypothesis

I have two hypothesis as below: Under $H_1$, $f_x(x) = 3/2 * x^2$ where $x \epsilon (-1,1)$ Under $H_0$, $f_x(x) =$ Uniformly distributed between $x \epsilon (-1,1)$ What is the maximum likelihood ...
