Invariant time-series factorization [PDF]
Data Mining and Knowledge Discovery, 2014 Time-series classification is an important domain of machine learning and a plethora of methods have been developed for the task. In comparison to existing approaches, this study presents a novel method which decomposes a time-series dataset into latent patterns and membership weights of local segments to those patterns.

Flavor content of nucleon form factors in the space- and time-like region [PDF]
, 2006 I discuss a two-component model of nucleon form factors in which the external photon couples both to an intrinsic three-quark structure and to a meson cloud via vector-meson dominance, and present a simultaneous analysis of the electromagnetic form ...
