Algorithms for Hyper-Parameter Optimization
We present hyper-parameter optimization results on tasks of training neural networks and deep belief networks using random search and two new greedy sequential methods based on expected improvement criterion. Expand

Learning and Design of Principal Curves
We define principal curves as continuous curves of a given length which minimize the expected squared distance between the curve and points of the space randomly chosen according to a given distribution. Expand

Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei
Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the highest-energies, which are correlated with the positions ofExpand

Correlation of the highest-energy cosmic rays with nearby extragalactic objects.
Using data collected at the Pierre Auger Observatory during the past 3.7 years, we demonstrated a correlation between the arrival directions of cosmic rays with energy above 6 x 10(19) electron voltsExpand

Principal curves: learning, design, and applications
The subjects of this thesis are unsupervised learning in general, and principal curves in particular. Principal curves were originally defined by Hastie [Has84] and Hastie and Stuetzle [HS89]Expand

Observation of the suppression of the flux of cosmic rays above 4 x 10 (19) eV.
The energy spectrum of cosmic rays above 2.5 x 10;{18} eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described. The spectral index gamma of the particle flux, JExpand
