A copy of the preliminary schedule for the upcoming NIPS conference
(November 28-December 1, with workshops December 1-3) appears below.  NIPS
is a single-track, purely scientific conference.  The program committee,
chaired by Scott Kirkpatrick, was very selective: only 25% of submissions
were accepted this year.  There will be 25 oral presentations and 60
posters.  The proceedings will be available around the end of April '89,
but they can be ordered now from Morgan Kaufmann Publishers, P.O. Box
50490, Palo Alto, CA 94303-9953; tel. 415-578-9911.  Prepublication price
is $33.95, plus $2.25 postage ($4.00 for overseas orders).  California
residents must add sales tax.  Specify that you want "Advances in Neural
Information Processing Systems".
