Clustering Analysis of Fast-ion Driven Instabilities

Beam ions often drive Alfv\'en eigenmodes and other instabilities unstable in DIII-D. Many of these modes have been unambigously identified but some frequently occurring features have been neglected. In this work, datamining analysis techniques [1] that successfully analyzed magnetics data from the H-1NF heliac are applied to arrays of magnetic and electron cyclotron emission (ECE) data from DIII-D. The techniques group instabilities with similar magnetic or ECE features into clusters. Once the clusters are found, a database of plasma parameters will facilitate mode identification.\par \vskip6pt \noindent [1] S.R. Haskey et al. , Comp. Phys. Comm. 185 (2014) 1169; B.D.
