Our aim for the 7th IDA conference is to bring together a wide variety of researchers - academic, industrial, and otherwise who are concerned with extracting knowledge from data, including researchers from statistics, machine learning, neural networks, computer science, pattern recognition, database management, and other areas. The strategies adopted by people working in these areas are often different, and a synergy results if this is recognised. IDA-2007 is intended to stimulate interaction between these different areas, so that more powerful techniques and tools emerge for extracting knowledge from data and a better understanding is developed for the process of intelligent data analysis.
