NOTE
Well we are getting into the quiet times of summer at least as far as
talks which means, I hope, that most of you are concentrating on
research. I may digress a bit in this calendar. My first digression
will be on wikis; how many of you are using a wiki to help your work
(e.g., like the Semantics lab wiki at http://semlab.stanford.edu/ ?
Are they useful and how? Drawbacks? Answers, if any, may be
summarized in a future calendar (a fuller summary may be put up on the
web somewhere).

SF BAY ACM TALK
on Wednesday, 20 June 2007, 6:30pm - 9:00pm
Hewlett Packard, Pruneridge and Wolfe, Cupertino, Bldg. 48, Oak Room
http://sfbayacm.org/
"Folding@Home"
Guha Jayachandran
Stanford University
http://www.stanford.edu/~guha/
Biological molecules and their associated phenomena are crucial to
life as we know it. The ability to simulate such phenomena would allow
for deeper fundamental understanding of basic life processes, help
elucidate diseases such as Alzheimer's, and offer the promise of
reduced costs and time in fields such as drug discovery. Paradoxically
given their small size, detailed physical simulation of biomolecules
requires massive amounts of computational power. This, along with
other factors, has long limited the problems that could be addressed.
Distributed computing and new computational technologies can help
address the challenge. Now with over 200,000 computers participating
worldwide, the Folding@Home project is more powerful for parallel
simulation than any supercomputer in the world. With the recent
addition of Sony PS3 participation, it has a sustained performance of
over 800 TFLOPS. This talk will describe advances in the technological
infrastructure of the project, and describe examples of methods that
have been developed to take advantage of parallelism.
About the Speaker: Guha Jayachandran is completing his Ph.D. in
computer science (Chemistry minor) at Stanford University under
Prof. Vijay Pande. He will graduate in June. Guha's interests include
computational drug discovery, novel applications of biocomputation,
and grid computing. He has worked on all aspects of Folding@Home -- a
worldwide distributed computing project examining protein biophysics
-- for over five years, also focusing during recent years on the
development of new computational methods for probing biomolecular
processes like drug binding.

"Bionic Technology for Mobility Assistance"
Robert Horst
Chief Technology Officer, Tibion Corporation
Powered mobility assistance devices, sometimes called active
orthotics, bionics, bio-robotics, or exoskeletons, could have a
tremendous impact on the quality of life for those with impaired
mobility. Advances in embedded computing, lightweight batteries, and
motor control electronics provide some of the needed technologies, but
the field has developed slowly while waiting for a suitable actuator
that meets all of the key requirements: 1) Strong enough to lift a
person, 2) Small and light enough to fit under the clothing 3)
Coupling/gearing to provide a range of speed/torque tradeoffs as well
as free movement, and 4) Highly efficient operation to power the
device for a full day with a small battery.
Tibion has been developing actuators, electronics and embedded
software to address the requirements for active orthotic devices. The
development has included fabrication and testing of many types of
actuators to deliver the required forces while minimizing size and
weight. The evolution of the design requirements and solutions will be
presented through photos, video and analysis of this series of
prototypes. These devices are based on new types of continuously
variable transmissions (CVTs) that provide the variable impedance
needed for bionic applications. The actuators deliver sufficient force
to aid in rising from a chair, the ability to deliver assistance force
while moving quickly, and unimpeded motion during the swing phase of
the gait. The discussion will include many aspects of developing an
active knee device using a CVT actuator.
About the Speaker: Robert Horst is Chief Technology Officer at Tibion
Corporation, a company he co-founded in 2002. He holds an BSEE degree
from Bradley University, a MSEE from the University of Illinois at
Urbana-Champaign, and a Ph.D. in computer science also from the
University of Illinois. He is a Fellow of the IEEE and holds 65 US
patents.

"Exploring Cost-Effective Approaches to Human Evaluation of
Search Engine Relevance"
Kamal Ali
Stanford University
Traditional Cranfield approaches to document relevance evaluation
involve judges making judgments on individual documents. The search
engine setting complicates matters by returning a *set* of summaries
of results competing with advertising and other links such as spelling
suggestions. Evaluation of the relevance of search results in such a
setting needs to account for set-level effects such as ensuring the
returned set does not contain duplicates or near-duplicates, that it
covers most of the common senses for the search query and that it
accurately ranks the results for the majority of the users. The talk
presents a framework of test types and explores the pros and cons of
each type. We compare cost-effective set-level judgments to item-level
judgments and identify the types of queries for which the item-level
methodology misses important aspects. This is work done at Yahoo and
presented at ECIR 2005.
Joint work with Chi Chao Chang and Yun-fang Juan.
About the Speaker: My research interests lie at the boundary of
application and theory in Information Extraction, Question Answering,
Parse-based Feature classification, Bootstrap Learning, Sampling in
databases, Active Learning and Bayesian Model Averaging.
My most recent set of papers is on sampling in databases based on an
application fielded at Yahoo for over two years supporting thirteen
internal analytics data-marts. Prior to that in the Web Search group,
I did work on statistical evaluation and competitive analysis of
search results which was important in Yahoo's decision to acquire
Inktomi. It also led to an ECIR paper on search evaluation framework.
My PhD is on Bayesian Model Averaging, which I received from UC
Irvine. After that I did research and consulting at IBM Almaden and
Stanford's CLL lab before leaving academia for TiVo. At TiVo, I led
the team that wrote the Suggestions Engine, a system for recommending
TV shows which runs partly in distributed form on over three million
Linux boxes (TiVo's). Following TiVo, I was a principal scientist
doing clickstream cluster analysis and text clustering at Vividence
(now Keynote).

"TiVo Suggestions: Predicting Viewer Affinity Using
Collaborative Filtering"
Kamal Ali
Stanford University
I will describe the TiVo TV-show collaborative recommendation system
which is fielded in over three million TiVos for seven years. Over
this install base, TiVo has more than 100 million ratings of
approximately 30,000 distinct TV shows and movies. TiVo uses an
item-item form of collaborative filtering which preserves privacy so
obviating the need to keep a memory on the server for each TiVo users
viewing preferences. Despite the high profile nature of this
collaborative filtering system, because of this strong privacy
protection approach, TiVo has suffered no privacy backlash. I will
also describe the distributed recommendation task which uses the three
million Linux TiVo clients as well as the highly scalable, throttled,
parallelized server-side architecture.
Joint work with Wijnand Van Stam.
