Alfred Hero - Interests in Signal Modeling
I am interested in modeling and representation of signals for
detection and classification applications. A principal objective has been to
detect features of a signal such as dimensionality, spectral support, and
other non-linear components using time-frequency, space-frequency, and
regression trees. A selection of recent papers follow.
