Hello again

It has been a while. The last post on this blog is from 2019, and the one before that from 2017. In the years since I’ve written plenty — in notebooks, in drafts, in papers — but very little of it landed here. This post is a short note to mark the restart.

What changed

• The theme. The old Skinny Bones setup was built on jQuery 1.9, Grunt, and Jekyll 3. It served me well, but pipe-cleaning it turned out to be harder than rebuilding. The new site runs on Astro with Markdown/MDX content, dark mode, view transitions, and KaTeX for math — familiar bones, modern skin.
• The scope. I’m still drawn to the ideas behind machine learning, but I’ll also be writing about evaluation, agents, and the practical side of building research tooling. Less tutorial, more notebook.

What’s coming

There’s a pile of old drafts on VAEs, GANs, attention, and reinforcement learning that I never published. Some of them still hold up — I’ll polish the better ones and post them, dated as historical pieces so the timeline stays honest. New writing will appear alongside them, not in place of them.

If you subscribed years ago and this arrives in your RSS reader: hi. I’m glad you’re still around.

P.S. — math still works, in case you need it:

$${\nabla }_{\theta }\mathcal{L}(\theta )={\mathbb{E}}_{x\sim p_{\text{data}}}[{\nabla }_{\theta }\log p_{\theta }(x)]$$
