Abstract.
The Empirical Mode Decomposition (EMD) was an empirical
one-dimensional data decomposition method invented by Dr. Norden Huang
about ten years ago and has been used with great success in many fields
of science and engineering. In this talk, I will introduce, from the
perspective of a physical scientist, the thinking behind and the
algorithm of EMD; and its most recent developments, especially the
Ensemble EMD (EEMD), a noise-assisted data analysis method. I will also
outline some open questions that we currently do not have answers, or
even clues to the answers, such as how to optimize EMD algorithm, what
is the mathematical nature of EMD. To a significant degree, this is a
talk intended for obtaining helps from mathematicians.
