Variational methods for Reinforcement Learning
We consider reinforcement learning as solving a Markov decision process with unknown transition distribution. Based on interaction with the environment, an estimate of the transit...

Analysis of template aging in iris biometrics
It has been widely believed that biometric template aging does not occur for iris biometrics. We compare the match score distribution for short time-lapse iris image pairs, with a...

Deformation-based nonlinear dimension reduction: Applications to nuclear morphometry
We describe a new approach for elucidating the nonlinear degrees of freedom in a distribution of shapes depicted in digital images. By combining a deformation-based method for mea...

Laplacian Distortion Model (LDM) for Rate Control in Video Coding
Abstract. In many rate control models, a uniform weighted distortion has been assumed; that is, the DCT coefficients of the motioncompensation difference frames (residues) conform...
