The Large Area Telescope (LAT) event analysis is the final stage in the event
reconstruction responsible for the creation of high-level variables (e.g.,
event energy, incident direction, particle type, etc.). We discuss the
development of TMine, a powerful new tool for designing and implementing event
classification analyses (e.g., distinguishing photons from charged particles).
TMine is structured on ROOT, a data analysis framework that is the de-facto
standard for current high energy physics experiments; thus, TMine fits
naturally into the ROOT-based data processing pipeline of the LAT. TMine
provides a visual development environment for the LAT event analysis and
utilizes advanced multivariate classification algorithms implemented in ROOT.
We discuss the application of TMine to the next iteration of the event analysis
(Pass 8), the LAT charged particle analyses, and the classification of
unassociated LAT gamma-ray sources.
