[Scikit-learn-general] Required number of neighbors in Local Tangent Space Alignment

Hi: Is there a lower bound for n_neighbors when using the the Local Tangent Space Alignment method with LLE? I get this warning /usr/local/lib/python2.6/dist-packages/scipy/linalg/decomp_lu.py:59: RuntimeWarning: Diagonal number 198 is exactly zero. Singular matrix. RuntimeWarning) when I ru
