arXiv Xplorer

arxivxplorer is a new semantic search engine for arXiv papers. At this point, it's a self-funded side project that looks promising. Enter a query in plain English and behind the scenes, it uses OpenAI's latest embedding model to find the most relevant papers. Or paste in an arXiv URL and it will search for papers that are similar. For info and examples, see this discussion on Twitter >>

Tutorials, Projects & Opinions

Matrices and graphs

The single most undervalued fact of linear algebra: matrices are graphs, and graphs are matrices. Encoding matrices as graphs is a cheat code, making complex behavior simple to study. This is a great tutorial — with lots of illustrations — that shows how.
