MUSIC 319: CCRMA HEARING SEMINAR
on Thursday, 1 July 2004, 11:00am
CCRMA Library, The Knoll
http://mambo.ucsc.edu/psl/ccrmas/ccrmas.html
Really, seriously. Laughter at this Thursday's CCRMA Hearing Seminar.
Old-time favorite, CCRMA-friend David Huron (from Ohio State) is back
to talk about auditory-evoked laughter and the role of expectations.
We all know that speech can evoke guffaws. But what about a sequence
of tones?
We'll try to keep David on topic, but I'm sure that this seminar will
be the usual romp through musical and auditory science. Lots of good
science and fun for all.
Note: this is probably the last Hearing Seminar at the Knoll for a
while. After 13 years, the Knoll's reconstruction is about to start.
Seminars in July will be at a location to be determined. Crazy, but
good times at CCRMA for a while.
See you at CCRMA. Bring your favorite laugh.

"Auditory-Evoked Laughter: The Role of Expectation"
David Huron
Cognitive and Systematic Musicology Laboratory, Ohio State
While most laughter involves some language-based humor, laughter can
also be evoked by stimuli without the presence of language. In the
music of P.D.Q. Bach, for example, simple sequences of pitches can
cause listeners to burst out laughing. Why?
Sixty-four live recordings of Peter Schickele's music were analyzed
and 629 moments of audience laughter were identified. Each moment was
classified according to the probable cause of the laughter. Excluding
language-based humor and visual gags, all of the identifiable moments
of laughter appear to be traceable to marked violations of
expectation. Some violations are schematic in origin while others
involve veridical violations of well-known musical passages. An
information theoretic analysis suggests that laughter is most likely
to occur when there is greater than a 100-fold difference in the
first-order probability between the expected outcome and the actual
outcome.
An evolutionary account is proposed that attempts to explain why the
behavioral response to such violations of expectation is the
distinctive punctuated exhaling ("ha-ha-ha ...") that defines
laughter.

CSLI TALK
on Thursday, 1 July 2004, 3:00pm-4:00pm
Ventura 17
"Computing with waves; neurons as resonators"
Tom Doris and Sean O Nuallain
Neuroscience has witnessed a healthy burgeoning of theory in the
period of the last decade, from revivals of Hoffman's geometry of
systems model, reformulated to stress the dynamical systems aspect, to
a similarly transformed holonomic theory by Grass and his colleagues,
to various cortical columnar architectures proposed, inter alia by
Anderson and Burnod, to further-fledged speculations featuring nitrous
oxide, glial cells, and quantum coherence in microtubules.
In contrast, computational models of the behavior of networks of
neurons are still mainly based on an integrate- and-fire model of
neural function. We propose a new computational model of the neuron
developed with spectral data processing in mind, which emphasizes
sub-threshold oscillation of the membrane potential as a fundamental
feature on which to build a computational model. This reformulation of
the computational neuron results in networks in which features such as
resonance, selective communication and sensitivity to inter-spike
periods emerge naturally. Furthermore, integrate and fire behavior
emerges as a special case of the new model.
Tom Doris recently successfully defended his PhD thesis, done under
the supervision of Sean O Nuallain at DCU. He has worked for the past
four years at Intel's research division in Shannon, Ireland. En route
to the central idea of his PhD, he implemented a virtual reality
environment with speech recognition, natural language processing and
gesture recognition. This was used to explore aspects of NLP and
particularly locative expressions and measures of visual
salience. Multimodal input and contextual disambiguation were key
features.
Sean O Nuallain holds an M.Sc. in Psychology from University College,
Dublin (UCD) Ireland & a Ph.D. in Computer Science from Trinity
College, Dublin, Ireland. He holds a visiting scholars' position at
Stanford and directs the independent non-profit Nous Research (
http://www.nous-research.com/ ). He is the author of a book on the
foundations of Cognitive Science: "The Search for Mind" (Ablex, 1995;
2nd ed Intellect, 2002; Third edition Intellect, 2003) and editor of
"Two Sciences of Mind" (Benjamins, 1997); editor of "Spatial
Cognition"; co-editor of "Language, Vision, and Music" (Benjamins,
2002) and of "Mind in Interaction" (Benjamins, in preparation). His
"Being Human: the Search for Order" (Intellect, 2002) sold out its
first print-run immediately; the second edition was launched at
Stanford Bookstore on May 19, 2004.

"Soundness and Completeness of
Expanded Abadi-Rogaway Logics of Formal Encryption"
Gergely Bana
University of Pennsylvania
We consider expansions of the Abadi-Rogaway logic of
indistinguishability of formal cryptographic expressions. The language
of the Abadi-Rogaway logic uses a box as formal notation for
indecipherable strings. In the expanded formalism we adopt, different
kinds of boxes are allowed, which - loosely speaking - correspond to
different kinds of indecipherable strings.
We establish soundness and completeness for a variety of
interpretations. Two such interpretations are discussed in detail: a
purely probabilistic one that interprets formal expressions in
One-Time Pad, and another one in the so-called type 2 (which-key
revealing) cryptosystems based on computational complexity.
Furthermore, we discuss a general, systematic treatment of expansions
of the logic as well as general soundness and completeness theorems
for interpretations.

"Go! agents go to the dance:
a multi-paradigm symbolic language for multi-agent systems"
Frank McCabe
Fujitsu Laboratories
Go! is a logic programming based language with distinct syntactic
features that directly support functional and object oriented
programming the latter based on Logic and Objects style of classes. It
is targeted at high integrity systems and at building agent systems.
We have used Go! to elaborate an agent architecture which is based on
the BDI principles but which supports concurrency internally and
externally: beliefs are updated and accessed asynchronously within the
agent by different modules with specific responsibilities such as
negotiation and world perception. In this talk I will introduce some
of the key features of Go!, focusing on the newer aspects of its class
notation. I will also show how an agent architecture such as outlined
above can be easily built; in the context of a multi-agent
demonstrator that uses agents negotiating over dances and drinks at a
ball.
About the Speaker: Frank McCabe is a Research Fellow at Fujitsu
Laboratories of America. His focus in multi-agent systems has been on
designing programming systems and tools to simplify the task of
building agent systems. He has also been active in recent years in
various standardization efforts, including the W3C Web Services
Architecture and the Foundation for Intelligent Physical Agents.
