The “Bird Plot”

Jessica Esquivel gave a very nice update last week at the MicroBooNE collaboration meeting about her work to use “deep learning” tools to separate muons and pions in the CC-Inclusive cross-section analysis.  She included this animation, which shows a “deep learning” algorithm learning how to distinguish between five different particle types.  This work was done using the SUrge GPU cluster at Syracuse University.

t-distributed stochastic neighbor embedding algorithm learning features to distinguish among five particle types.

ArgoNeuT event in the CERN Courier

An ArgoNeuT Event

The current edition of the CERN Courier features a very nice article by Prof. Ulrich Mosel about the importance of improving the modeling of neutrino-nucleus interactions.  An event display from ArgoNeuT is included to illustrate the complexity of such interactions.  Here’s that same event, showing the Collection plane view too!  It’s most likely a deep-inelastic scattering event, with what appears to be a very interesting backwards-traveling proton.
