Adrian Hill @adrianhill.de · 25/08/2026Added a much needed tangent space slider to my website adrianhill.de (desktop experience™ only, sorry). 140

Adrian Hill @adrianhill.de · 03/12/2025I'm excited to see whether our idea translates to general MC integration over Jacobians and gradients outside of XAI. Please don't hesitate to talk to us if you have ideas for applications! 120
Adrian Hill @adrianhill.de · 03/12/2025Our proposed SmoothDiff method (see first post) offers a bias-variance tradeoff: By neglecting cross-covariances, both sample efficiency and computational speed are improved over naive Monte Carlo integration. 120
Adrian Hill @adrianhill.de · 03/12/2025To reduce the influence of white noise, we want to apply a Gaussian convolution (in feature space) as a low-pass filter. Unfortunately, this convolution is computationally infeasible in high dimensions. Naive Monte Carlo approximation results in the popular SmoothGrad method. 120
Adrian Hill @adrianhill.de · 03/12/2025Input feature attributions are a popular tool to explain ML models, increasing their trustworthiness. In this work, we are interested in the gradient of a given output w.r.t. its input features. Unfortunately, gradients of deep NN resemble white noise, rendering them uninformative: 130
Adrian Hill @adrianhill.de · 03/12/2025Join us today from 4:30 to 7:30 PM @neuripsconf.bsky.social Hall C,D,E #1006 for our poster on SmoothDiff, a novel XAI method leveraging automatic differentiation. 🧵1/6 1115
Adrian Hill @adrianhill.de · 03/11/2025Working on a poster in Typst again. But this time from scratch without any package dependency. 💪 160
Adrian Hill @adrianhill.de · 28/07/2025The perfect use case for UnicodePlots.jl! github.com/JuliaPlots/U... 390
Adrian Hill @adrianhill.de · 14/05/2025According to the Typst team, PDF submissions should be allowed, I hope this is correct: info.arxiv.org/help/submit_... 020
Adrian Hill @adrianhill.de · 14/05/2025I had to endure some teasing from my collaborators for choosing to write our NeurIPS submission in @typst.app – looks like I have one more reason to believe I made the right call... 😅 3142
Adrian Hill @adrianhill.de · 30/04/2025Today is a good day, dyed a shirt and made it the front page of HN 🥹 170
Adrian Hill @adrianhill.de · 24/04/2025If you are at #ICLR2025 and want to chat about automatic sparse differentiation (or just grab a sticker), come see me at poster 471! 1174
Adrian Hill @adrianhill.de · 23/04/2025From the Singapore Pavillon at #EXPO2025 to the real thing at #ICLR25! 030
Adrian Hill @adrianhill.de · 14/04/2025The announcement of the "Julia for Machine Learning" course is my most shared skeet on old-BlueSky. Since then, the course material has been extended to include package development in #JuliaLang! 📖: github.com/adrhill/juli... 12010
Adrian Hill @adrianhill.de · 13/02/2025I previously built a more minimalist, low-profile Bluetooth keyboard, but it ended up being too difficult to switch to when I needed to get work done. So this one is pretty much the opposite. #ergomech #splitkeyboards 220
Adrian Hill @adrianhill.de · 13/02/2025Completed my post preprint project: a split keyboard to help with my wrist pain (pictured with the pain-relieving gel it is trying to replace). 3142
Adrian Hill @adrianhill.de · 30/01/2025We demonstrate that even for one-off computations, end-to-end ASD (yellow line) outperforms AD! When the sparsity pattern can be reused, the performance improvements are even more significant (green line). 140
Adrian Hill @adrianhill.de · 30/01/2025The bottleneck of previous ASD implementations is the detection of sparsity patterns. We describe a faster implementation of pattern detection based on operator overloading which is compatible with generic code bases. 160
Adrian Hill @adrianhill.de · 30/01/2025However, many of these matrices exhibit sparsity, a property that can be leveraged to speed up AD by orders of magnitude. We call this automatic sparse differentiation (ASD). While known in the AD community, it remains largely ignored in the ML literature. 170
Adrian Hill @adrianhill.de · 30/01/2025You think Jacobian and Hessian matrices are prohibitively expensive to compute on your problem? Our latest preprint with @gdalle.bsky.social might change your mind! arxiv.org/abs/2501.17737 🧵1/8 314028
Adrian Hill @adrianhill.de · 07/12/2024From the book, here are some beautiful examples of using mathematical optimization as a tool in art! 240
Adrian Hill @adrianhill.de · 07/12/2024This beauty by @baabbbaash.bsky.social just arrived the mail! Looks like my next #JuliaLang holiday project is now set. 2251
