    "Information Theory, Probability and Neural Networks"
	
               by David J.C. MacKay
-------------------------------------------------------------------------

     An undergraduate / graduate textbook. 
     This book will feature:

		* lots of figures and demonstrations.
		* more than one hundred exercises with worked solutions.
		* up to date exposition of:
		   .  source coding 
			- including arithmetic coding, `bits back' coding
		   .  channel coding 
			- including Gallager codes, turbo codes
		   .  neural networks
			- including Gaussian processes
		   .  Monte Carlo methods
			- including Hybrid Monte Carlo, Overrelaxation

     The current draft (April 9th 1997) is     Draft 1.2.3  (308 pages).
     (Estimated to be about 70% complete.)
