| Quantum Computing Day 2: Image Recognition with an Adiabatic Quantum Computer |
 |
Google Tech Talks
December, 13 2007
ABSTRACT
This tech talk series explores the enormous
opportunities afforded by the emerging field
of quantum computing. The exploitation of
quantum phenomena not only offers tremendous
speed-ups for important algorithms but may
also prove key to achieving genuine synthetic
intelligence. We argue that understanding
higher brain function requires references to
quantum mechanics as well. These talks look
at the topic of quantum computing from
mathematical, engineering and neurobiological
perspectives, and we attempt to present the
material so that the base concepts can be
understood by listeners with no background in
quantum physics.
In this second talk, we make the case that
machine learning and pattern recognition are
problem domains well-suited to be handled by
quantum routines. We introduce the adiabatic
model of quantum computing and discuss how it
deals more favorably with decoherence than
the gate model. Adiabatic quantum computing
can be understood as an annealing process
that outperforms classical approaches to
optimization by taking advantage of quantum
tunneling. We also discuss the only
large-scale adiabatic quantum hardware that
exists today, built by D-Wave. We present
detailed theoretical and experimental
evidence showing that the D-Wave chip does
indeed operate in a quantum regime. We report
about an object recognition system we
designed using the adiabatic quantum
computer. Our system uses a combination of
processing steps, where some are executed on
classical hardware while others take
advantage of the quantum chip. Both interest
point selection and feature extraction are
accomplished using classical filter
operations reminiscent of receptive field
properties of neurons in the early visual
pathways. Image matching then proceeds by
maximizing geometrical consistency and
similarity between corresponding feature
points, which is an NP-hard optimization
problem. To obtain good solutions, we map
this to the problem of finding the minimum
energy in an Ising model in which the
vertices represent candidate match pairs,
bias terms reflect feature similarity, and
interaction terms account for geometric
consistency. The adiabatic quantum computer
is then employed to find a low energetic
minimum of the Ising dynamics. We conclude
with a look towards which type of machine
learning problems maybe most suitable for
mapping to a quantum computing architecture.

Vancouver Sun, Vancouver magazine, The Globe
and Mail, The National Post, USA Today, MIT
Technology Review magazine, the Harvard
Business Review and Business 2.0 magazine,
and one of his business strategies was
profiled in a Harvard Business School case
study. He has received several awards and
accolades for his work with D-Wave, including
being short-listed for a 2005 World
Technology Award.
Dr. Rose holds a PhD in theoretical physics
from the University of British Columbia,
specializing in quantum effects in materials.
While at McMaster University, he graduated
first in his class with a BEng in Engineering
Physics, specializing in semiconductor
engineering.
Since the inception of D-Wave in 1999, Dr.
Rose, as founding CEO, raised over $45M on
behalf of the company, including a round led
by Draper Fisher Jurvetson (DFJ) — the

| Windows Vista speech recognition - the whole story |
 |
While I don't particularly like Microsoft,
and found the Vista speech recognition gone
wrong clip a good joke, several Microsoft
blogger pointed out the that it was a case of
selective media editing. I was interested in
getting the whole story so I downloaded the
70mb MSFT Financial Analyst Meeting 2006:
Steve Ballmer clip from here
http://www.microsoft.com/msft/speech/FY06/Bal
lmerFAM2006.mspx
Knowing there were probably others who wanted
to see it but didn't wish to retrive the
whole file, I cut it to show the entire
speech recognition part. If you haven't yet
seen the CNBC selectively edited clip, I
suggest you watch it here
http://www.youtube.com/watch?v=2Y_Jp6PxsSQ
Having seen this, while I still find the
original clip funny, it's clear the bigger
joke is on CNBC for their selective,
misleading editing and (rather silly as well)
commentary...
The issues and reasons for the failure are
discussed here

I'm not 100% sure on the copyright status, I
hope that since Microsoft makes the entire
clip available on their website and the CNBC
selectively edited/misleading clip is
available, they won't mind. If they do, tell
me and I will remove it ASAP.
N.B. As I hope I made clear above. I am NOT
associated in any way shape or form with
Microsoft, so please don't accuse me of being
so

| Vista speech recognition - the big surprise |
 |
Surprise surprise. Windows Vista speech
recognition actually works. Contrary to what
MSNBC criticize as a "wreck," the speech
recognition technology is well developed and
highly usable.
Is Microsoft is intentionally trying to lower
our expectations with Vista so when it
finally does come out the public will be
blown away? Scary...
From the source of this video:
"I got my hands on the July CTP build (5472)
of Windows Vista and gave it a try, and I
recorded what I found. I used the internal
microphone array in my laptop, so the sound
quality is not optimal but Vista handled it
well."
"In addition: There is a whole lot more to
speech recognition than what I have
demonstrated. Even many basic features that I
haven't demonstrated, like spelling out a
name or technical word. So don't think what
you see is what you get, having said that,
the possibilities of speech recognition in a
Tablet PC or Media Centre is mind-blowing. I
thank everyone who enjoyed the video."
"In addition addition: A lot of people also
noticed that I had to repeat a bit of what I
said. This is primarily my fault. In the
speech control panel, you would often see a
blue rotating circle. This is to indicate the
speech recogniser is currently busy checking
what is on-screen. Also, Camtasia the screen
recording tool is very CPU intensive, so
there was less processing power was available
for the speech recogniser. I sometimes spoke
too quickly between commands, so it hasn't
fully analysed all the available options yet.

Directed by Jehane Noujaim (Egypt/USA)
This short documentary offers a unique and
intimate perspective into the thoughts of a
Moroccan imam and his wife as they discuss
their romance. They describe their thoughts
about how to build a deep, trusting, and
enduring relationship in this film that shows
the specific ways the Islamic faith relates
to the universal concepts of love and
respect.
Jehane Noujaim is the director of, among
other films, the award-winning documentaries
Control Room and Startup.com. Raised in
Cairo, Egypt, she attended Harvard University
and graduated magna cum laude with a degree
in Visual Arts and Philosophy. She has worked
for MTV's News and Documentary Division as a
segment producer for the series Unfiltered,
and as a director and cinematographer on
films such as Born Rich, Only the Strong
Survive, and Down from the Mountain. In 2006,
Noujaim won the prestigious TED Prize, an
annual award in which the recipients are
granted a wish. Jehane's wish -- to create a
day in which the world comes together through
film -- was the catalyst for Pangea Day.

| Recognition of the 17th Karmapa |
 |
The Gyalwa Karmapas have been the spiritual
heads of the Karma Kagyu School of Tibetan
Buddhism since the 12th century and have
worked tirelessly for the benefit of all
sentient beings. The 17th Karmapa was born in
Tibet in May 6, 1983. He is the son of Mipham
Rinpoche, a renowned scholar and master of
the Nyingma Lineage and Dechen Wangmo, a
direct descendant of the legendary King Gesar
of Ling. In keeping with the tradition of the
Karmapas recognizing themselves, as a very
young child Thaye Dorje repeatedly proclaimed
he was the Karmapa. This message along with
other clear indications reached the 14th
Kunzig Shamarpa who is second in rank to the
Gyalwa Karmapas. The Shamarpa therefore
examined the boy in accordance with the
centuries-old spiritual tradition of the
Karma Kagyu School and confirmed that Thaye
Dorje was the authentic Karmapa
reincarnation. On March 17, 1994 an official
ceremony took place in New Delhi and Trinley
Thaye Dorje was formally recognized and
enthroned as the 17th Gyalwa Karmapa, the
genuine Holder of the Black Crown.
The 17th Karmapa has embraced the modern
world -- he speaks fluent English, has
studied many Western academic subjects and is
proficient with computer and communication
technologies. The Karmapa mainly resides at
his headquarters in Kalimpong, India and at
his European seat in Dordogne, France.
This video was sponsored by Siddhartha
Foundation International, a 501c3 non-profit
organization founded to support the
activities of the 17th Gyalwa Karmapa.
