Abstract: Machine learning (ML) tools have empowered a qualitatively new way to perform differential cross section measurements whereby the data are unbinned, possibly in many dimensions. Unbinned measurements can enable, improve, or at least simplify comparisons between experiments and with theoretical predictions. Furthermore, many-dimensional measurements can be used to define observables after the measurement instead of before.  In this talk, I will introduce new methods for ML-based unfolding/deconvolution, discuss public results using these methodologies, and end with challenges for the future.
