Notes and Tones

Hey, I'm Lorenz
  • Research Interest: splitting methods, operator theory for signal processing, average-case analysis of iterations
  • Past Software Projects: Vim, Rust
  • Clarinets, Gambe, Jitterbugs
  • Please drop a line if something resonates with you and we can have a chat

My main study focus are first-order methods [Bec17] under stochasticity, (total) asynchronicity assumptions and their application to parsimonious models for low-complexity inference. In that, I'm interested in Lyapunov stability, invex functional structures and cardinality constraint relaxation for sparse learning (e.g., for tree structured filterbanks), operator sparsification and factorization.

Before falling into the opt stew, I felt the joy of safe abstraction in projects with the Rust language. I'm a supporter of the Rust Machine Learning Group, past maintainer of Linfa [SLL23] and currently working on safe automatic differentiation compiler support for rustc.

I'm also host and user of the Mastodon instance for connected thoughts and an avid Vim and Linux user.

Besides that I really like making music. I play clarinets and currently learning a bass viola da gamba for diversion. You can also find me dancing afro-american vernacular dances in Jitterbug style such as Shag, Lindy Hop and Balboa on floors.

I got an education at RWTH Aachen studying electrical engineering and computer science.
