This Volume Was Written As A Result of The stat-log Project, Funded Under The Esprit Programmer of The European Union. In Addition to The Experimental Results, The Project Had The Desirable Effect of Encouraging Collaboration, Overdue In This Field, Between Workers In Different Disciplines. The Intersection of, And Interaction Between Machine Learning And Statistics Is Now A Rapidly Growing Area of Interest. There Are Obvious Areas of Common Research, The Main One Being Classification, But Communication Has Been Hampered By Use of Different Language And Terminology. In This Volume, Statisticians, All Workers In Machine Learning, And Neural Net Specialists Have Come Together In New Patterns of Interaction And Collaboration. We Offer This Book As A Source of Useful Information For Workers In Medicine, Agriculture, Industry, Finance And Other Applied Studies. We Also Hope That It May Contribute To The Spread of Similar Collaborations In The Scientific Community At Large, As Well As Further Research At The Interface of Machine Learning And Statistics.
