"Learning Requires Binding: Overcoming the Context Deadlock"
Christoph von der Malsburg

and
Computer Science Department and Program in Neuroscience

http://organic.usc.edu:8376/~dyweb/
To understand the brain, four fundamental questions must be answered:
a) What is the data structure of brain states?
b) How are brain states organized?
c) What is the data structure of memory?
d) What is the mechanism of learning?
Underlying all these questions is the problem of how do our brains
self-organize or, put another way, how do we learn from experience?
Learning in artificial neural networks, for instance, is restricted to
inputs of no more than about 100 bits per input pattern, whereas our
senses deliver millions of bits per pattern. I will argue that the
problem is due to a deadlock: signals are context-dependent, so that
learning is not possible without prior recognition of context, while
recognition of context, seems to require prior learning. I will show
how this deadlock can be broken by using a central binding mechanism
and rapid reversible synaptic plasticity. I will conclude by
discussing issues raised (at Stanford and elsewhere) that call
temporal signal binding into question.
About the Speaker: Dr. Malsburg received his Ph.D. in Physics from the
University of Heidelberg in 1970. From 1974 to 1987, he was a Senior
Member of the Scientific Staff of the Department of Neurobiology at
the Max-Planck-Institute for Biophysical Chemistry. He heads the
Institute for Neuroinformatics (together with Prof. Gregor Scheoner)
at Ruhr-University Bochum and the Computational Vision Lab at the USC
in Los Angeles. His research interests involve: (1) computational
studies of the formation of maps and feature detectors in the nervous
system; (2) development, application and experimental verification,
both neurobiological and computational, of the dynamic link
architecture, which uses changes in synaptic connectivity to conduct
pattern processing as well as long-term storage; (3) problems in
vision including invariant representation and recognition of objects,
implementation of low-level vision problems in dynamic link
architecture, and presentation of scenes in hierarchical nets. Other
problems in neural networks include spatial coordinate representation,
adaptive coordination between different (e.g., visual-motor)
coordinate systems, and the representation and generation of motor
patterns in neural nets.

"Understanding the Neural Basis of Episodic Memory
(What's language got to do with it?)"
Lokendra Shastri
International Computer Science Institute, Berkeley, CA
http://www.icsi.berkeley.edu/~shastri/
We readily remember events and situations in our daily lives and
acquire memories of specific facts by watching a telecast, reading a
newspaper, or participating in a dialogue. This remarkable "one-shot"
mnemonic ability poses a challenge for cognitive and computational
neuroscience.
It is reasonable to assume that the construal of an experience (or
utterance) in terms of an event is initially expressed as a pattern of
activity over distributed neural circuits in the brain. This
expression, however, is per force transient, since it must change
continually as we interact with the environment. Hence, the transient,
activity-based expression of a memorable event must be transformed
rapidly into a persistent structural encoding, or else it would be
lost. How does the brain perform this rapid transformation?
Events and situations are relational instances and not mere feature
vectors. What is the transient, activity-based representation of a
relational instance? What is the persistent, structure-based encoding
of a relational instance?
How do memories of specific events respond to partial cues, yet
exhibit strong pattern separation? How do such memories interact with
representations of general semantic knowledge during memory retrieval
and inference?
I will review ongoing work on biologically grounded computational
modeling of memory and reasoning that attempts to address these
questions, present some results, and discuss some predictions about
the representation and processing of relational information in the
brain. Some of the predictions are supported by recent empirical
findings, some others point the way to interesting experimental
studies.

"Active Learning with Multiple Views"
Ion Muslea
University of Southern California
http://www.isi.edu/~muslea/
Despite the practical success of machine learning in many real world
domains, labeling the training data is time consuming, tedious, and
error prone. In this talk, I focus on reducing the need for labeled
data in multi-view learning tasks. The key characteristic of
multi-view tasks is that the target concept can be independently
learned within different views (i.e., disjoint sets of features that
are sufficient to learn a concept). For instance, a robot can avoid
obstacles based on sonar, laser, or vision sensors; similarly, a Web
page can be classified either based on the words in the document or
based on the words in the HTML hyperlinks pointing to it.
In order to reduce the need for labeled data, I use active learning
algorithms that detect and ask the user to label only the most
informative examples in a domain. I introduce a family of multi-view
active learners that are based on the idea of learning from mistakes.
More precisely, they query examples on which the views predict a
different label: if two views disagree, one of them is guaranteed to
make a mistake. I also show that existing multi-view learners perform
unreliably if the views are inadequate. To cope with this problem, I
introduce two complementary solutions. First, by interleaving
bootstrapping and active learning, I obtain a novel multi-view learner
that has a robust behavior over a wide spectrum of domains that have
inadequate views. Second, I introduce a meta-learning algorithm that
is first trained on several solved learning tasks and then predicts
whether or not the views are "sufficiently adequate" for solving a
new, unseen learning task. I evaluate these three novel algorithms on
a variety of real-world domains, from information extraction and text
classification to advertisement removal and discourse tree parsing.
The empirical results show that my algorithms consistently outperform
existing state-of-the-art learners.

"Challenges in the Computational Discovery
of Scientific Knowledge"
Pat Langley
Computational Learning Laboratory, CSLI
http://cll.stanford.edu/~langley/
The growing amount of scientific data has led to the increased use of
computational discovery methods to understand and interpret them.
However, most work has relied on knowledge-lean techniques like
clustering and classification learning, which produce descriptive
rather than explanatory models, and it has utilized formalisms
developed in AI or statistics, so that results seldom make contact
with current theories or scientific notations. In this talk, I present
a new approach to computational discovery that encodes explanatory
scientific models as sets of quantitative processes, simulates these
models' behavior over time, incorporates background knowledge to
constrain model construction, and induces these models from
time-series data in a robust manner. I illustrate this framework on
data and models from Earth science and microbiology, two domains in
which explanatory process accounts occur frequently. In closing, I
describe our progress toward an interactive software environment for
the construction, evaluation, and revision of such explanatory
scientific models.
This talk describes joint work with Kevin Arrigo, Stephen Bay, Lonnie
Chrisman, Dileep George, Andrew Pohorille, Javier Sanchez, Dan
Shapiro, and Jeff Shrager.

"From Counterculture To Cyberculture:
How The Whole Earth Catalog Brought Us 'Virtual Community'"
Fred Turner
Communication, Stanford
In 1993, just as the Internet was emerging into public consciousness,
journalist Howard Rheingold brought a new phrase to public discussions
of computer-mediated communication: "virtual community." Within
months, the phrase had been taken up by researchers, programmers, and
corporate CEO's. For a time, virtual communities seemed poised to
become one of the defining social formations - and business plans --
of the Internet age. Yet, the notion of "virtual communities"
substantially predates the public emergence of computer
networking. This presentation traces the origins of the concept in the
Whole Earth network of publications and people. Drawing on archival
research and extensive interviews, the presentation will show how the
notion of virtual community first emerged as a day-to-day "contact
language" on the Whole Earth 'Lectronic Link (the WELL). It will then
show how both the communities who used the early WELL system and the
system itself represented networks and networking habits of mind first
developed around the Whole Earth Catalog some twenty years earlier.
By tracing the migration of countercultural ideas and practices into
the digital realm, I hope to raise questions about the role culture
plays in shaping our perceptions of emerging digital technologies.
There will be lots of time for discussion.
About the Speaker: Fred Turner is an Assistant Professor in Stanford's
Department of Communication whose teaching and research focus on the
cultural contexts of computing. A cultural historian, he is the author
of Echoes of Combat: The Vietnam War in American Memory (1996 & 2001).
He is currently researching the impact of Stewart Brand and the Whole
Earth network on contemporary visions of cyberculture and the "new"
economy.

"Scalar Phenomena and Polarity:
at the Interface of Grammar and Pragmatics"
Gennaro Chierchia
Milan
Over the recent past, there has been substantive progress in our
understanding of the semantics of Negative Polarity Items (NPIs); i.e.
rather convincing hypotheses have been put forth that make us readily
see why they have the peculiar distribution they have (e.g. Kadmon and
Landman 1993, Krifka 1995, Lahiri 1998). There have also been, even
more recently, important breakthroughs in our understanding of Free
Choice Items (e.g. Dayal 1998, Kratzer and Shimoyama 2002). It is well
known that there is a robust link between NPIs and FCIs, as extensive
typological studies reveal that roughly one half of the languages use
the very same morphemes for the two type of items (while the other
half resorts to separate series - cf. e.g. Haspelmath 1996). The
questions that we will address against this background are the
following:
i. How far along are we in getting an integrated view of FC vs. NP
phenomena?
ii. Many approaches appeal to implicatures in connection with
polarity items. What role do they play?
iii. How does pragmatics interact with "core" grammar?

"Mosaicing Impossible New Views"
Shmuel Peleg
Hebrew University
Most image rendering methods try to mimic real cameras by generating
images having the perspective projection. In contrast, a unique power
of image mosaicing is the ability to generate new views with
"impossible" projections which are not perspective. This can be done
with mosaicing methods that construct a panoramic mosaic image by
stitching together narrow strips, each strip taken from a different
source image. A different selection of strips gives a different
mosaicing effect using the same set of source images. For example,
given a sequence of source images from a camera moving sideways, a set
of mosaic images can be generated providing a virtual walkthrough in
the scene, including forward motion. And this is done without
recovering any 3D geometry and without calibration. In another
example, a set of full panoramic stereo views can be generated, even
though perspective cameras allow only a very narrow view for stereo
images. The power of mosaicing to generate such "impossible" views is
a result of the new family of projections that can be
constructed. These projections, the "Crossed Slits" projections, will
be defined and analyzed together with the appropriate mosaicing.
About the speaker: Shmuel Peleg received the BSc degree in mathematics
from The Hebrew University of Jerusalem, Israel, in 1976 and the MSc
and PhD degrees in computer science from the University of Maryland,
College Park, in 1978 and 1979, respectively. He has been a faculty
member at the Hebrew University of Jerusalem since 1980 and has held
visiting positions at the University of Maryland, New York University,
and the Sarnoff Corporation. His recent research interests include
image motion analysis and image mosaicing.
