The conception of fresh ideas and the development of new techniques for
Blind Source Separation and Independent Component Analysis have been
rapid in recent years. It is also encouraging, from the perspective of
the many scientists involved in this fascinating area of research, to
witness the growing list of successful applications of these methods to
a diverse range of practical everyday problems. This growth has been
due, in part, to the number of promising young and enthusiastic
researchers who have committed their efforts to expanding the current
body of knowledge within this field of research. The author of this book
is among one of their number. I trust that the present book by Dr. Mark
Girolami will provide a rapid and effective means of communicating some
of these new ideas to a wide international audience and that in turn
this will expand further the growth of knowledge. In my opinion this
book makes an important contribution to the theory of Independent
Component Analysis and Blind Source Separation. This opens a range of
exciting methods, techniques and algorithms for applied researchers and
practitioner engineers, especially from the perspective of artificial
neural networks and information theory. It has been interesting to see
how rapidly the scientific literature in this area has grown.
