Verify whether it's a Bregman loss function, maybe by solving a differential equation
I have a function $f(x, y;\mu) = \frac{\mu}{x}(x-y)^2$, where $\mu > 0$ is a parameter. I want to see whether it's a Bregman loss function. A Bregman loss function is define as:
$D_\phi(x,y) = \phi(...

How to obtain the parameter update for the multiclass classification (general loss and activation function)?
Consider the feature space $\mathcal{X}=\mathbb R^{d}$ and $\mathcal{Y}=\{1,...,c\}$ such that $c > 2$. We consider some activation function $\alpha: \mathbb R^{c} \to \mathbb R^{c}$ and out weight ...
