feeling a bit under the weather this week … thus an increased level of activity on social media and blog: kyunghyuncho.me/i-sensed-anxie…

Kyunghyun Cho is correct in saying that "the current crop of PhD students [...] are being left out" of the modern AI hiring pipeline, but it's even worse than that. Those who do get hired are often left unsatisfied that they're expected to build products instead of doing research.

Following our recent experiments I wrote more notes on Matcha TTS design alphacephei.com/nsh/2025/01/03…

"GPUs, assemble" - Captain Nvidia

At NUS Hackers today too. Favourite project: gyatword.com. Wordle-style gen-alpha slang crossword puzzle. I'm a millennial and I only can get 3 right, lol

Interesting observation. Although not formally proven yet.

Kubeflow Pipelines is VERY hard to use. I find myself drowned in an ocean of documentation, especially with the V2 migration. Anyone facing the same infra setup pain points? Or are there easier solutions out there?

Many exciting recent works on critique+ improving FAD! Time to update the toolkit repo lol

I am pleased to announce a new version of my RL tutorial. Major update to the LLM chapter (eg DPO, GRPO, thinking), minor updates to the MARL and MBRL chapters and various sections (eg offline RL, DPG, etc). Enjoy! arxiv.org/abs/2412.05265

torchlpc v0.7 * All kernels are rewritten in C++/CUDA * New parallel scan kernel for CPU * Running 1.2 to 2 times faster on GPU * Return final delay values (aka `zf`) See release notes for more details. github.com/DiffAPF/torchl…

Built a bunch of assistive tools to help musicians on BandLab create better with AI (Voice Changer, audio-to-MIDI, Recompose...) The best part is to see them on "combo" - combining these tools into an actual workflow. Check out the full suite here! bandlab.com/ai

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers. The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

If you are interested in `modulation extraction` for synth parameter inference (which most of the synth presets out there are modulated), do check out this work! It's super wonderful to get to work with Christopher Christopher Mitcheltree (finally!!)

Malaysia now has her very own Chopin Competition prize winner! Vincent Ong from Penang won 5th prize in this very prestigious piano event 🎉 His performance in the third round was much applauded for his elegance and unique interpretation: youtu.be/jN8y20xwVp4?si…

🌶️ Some (perhaps) spicy thoughts. It’s been a while since my last tweet, but I wanted to write about how disorienting it has been from academia to an LLM lab 😅 The kind of research I was trained to do during my PhD almost doesn’t exist here. The obsession with mathematical
