Fast operator-overloading Jacobian and Hessian sparsity detection.
Things I made and open sourced.
A list of software packages and tools I maintain or have shipped.
Spotlight
These are the projects I'm currently most proud of and excited about:
A common interface to most automatic differentiation backends in the Julia ecosystem. Work with Guillaume Dalle.
I've authored a course on Julia Programming for Machine Learning at TU Berlin.
Blog posts on best practices for Julia development. Goes into detail on how to write, debug, profile, optimize and share code in form of a Julia package. Work with Guillaume Dalle and Jacobus Smit.
Probably the world's most sophisticated dithering software. 30 dithering algorithms that can be applied in black & white, per color channel or using arbitrary color palettes. Includes automatic color palette generation and Unicode outputs.
Explainable AI
The Julia-XAI organization hosts Explainable AI methods written in Julia, with a focus on post-hoc, local input-space explanations of black-box models. In simpler terms, methods that try to answer the question "Which part of the input is responsible for the model's output?".
Collection of Explainable AI methods in Julia. Classical Gradient-based methods, input augmentations and GradCAM.
Layerwise Relevance Propagation and Concept Relevance Propagation for use with Flux.jl.
Heatmaps for vision models. For use with or without Julia-XAI methods.
Heatmaps for language models. For use with or without Julia-XAI methods.
Other packages
Obfuscate your Julia code by replacing it with emoji. Includes some horrible (great) puns. Work with Théo Galy-Fajou.
Julia macros to surf the web, browse code, and file issues from the comfort of your REPL.
Julia reimplementation of Total Variation Regularized Numerical Differentiation.
Color quantization algorithms for automatic color palette generation.
Scrape BoardGameGeek.com, the IMDB of board games. I originally wrote this package for a data analysis blog post that never happened.
Convert Jupyter notebooks to Pluto notebooks. Initially written for the JuML course.
Julia Testsets with points. Written to grade homework for the JuML course.
