Query: Kepler Eclipsing Binary Stars. III. Classification of Kepler Eclipsing
  Binary Light Curves with Locally Linear Embedding   We present an automated classification of 2165 \textit{Kepler} eclipsing
binary (EB) light curves that accompanied the second \textit{Kepler} data
release. The light curves are classified using Locally Linear Embedding, a
general nonlinear dimensionality reduction tool, into morphology types
(detached, semi-detached, overcontact, ellipsoidal). The method, related to a
more widely used Principal Component Analysis, produces a lower-dimensional
representation of the input data while preserving local geometry and,
consequently, the similarity between neighboring data points. We use this
property to reduce the dimensionality in a series of steps to a one-dimensional
manifold and classify light curves with a single parameter that is a measure of
"detachedness" of the system. This fully automated classification correlates
well with the manual determination of morphology from the data release, and
also efficiently highlights any misclassified objects. Once a lower-dimensional
projection space is defined, the classification of additional light curves runs
in a negligible time and the method can therefore be used as a fully automated
classifier in pipeline structures. The classifier forms a tier of the
\textit{Kepler} EB pipeline that pre-processes light curves for the artificial
intelligence based parameter estimator.
