This is a test
This is a test.
This year, I want to experiment with posting some of my expository notes and small research musings in a blog format. This is a test of Bay’s blogging functionality.
As this is just a test, let’s try rendering a multiline equation directly from my notes:^{1}
\begin{align}
\mathbf{h}^{(0)}(\mathbf{x}) &= \mathbf{x} \in \mathbb{R}^{n_0}
\\\
\mathbf{h}^{(\ell)}(\mathbf{x}) &= \frac{1}{\sqrt{n_{\ell1}}} \mathbf{W}^{(\ell)} \phi_{\ell}(\mathbf{h}^{(\ell1)}(\mathbf{x})) \in \mathbb{R}^{n_{\ell}} \qquad \ell = 1, \ldots, L .
\end{align}
Footnotes

As noted in Mufan Li’s issue related to rendering of multiline equations, the newline command
\\
must be escaped; like him I find that\\\\
is not sufficient, but\\\\\\\\
works. ↩
