HelloWorld This is a simple test for my first blog article.
Mathjax Test 1 $$a_{PI}(x|D) = E[u(x) | x, D] = \int_{-\infty}^{f’} \mathcal{N}(f; \mu(x), \kappa(x, x)) \ df =\phi(f’; \mu(x), \kappa(x, x))$$
Test 2 $$\frac{e}{\left( e+e^{\pi} - \pi^{e}\right) ,\left( - e+\pi^{e}\right) }+{E(\left( e+\pi\right) ,\left( 2,e+\pi\right) )}^{e}$$
