I would like to thank Tucker Balch for his suggestion. A few other
comments I have received implicitly point to the same idea.
This is a major version: all the questions about politics have been
removed. The 6 brain principles have been clarified.
Reminder: BMI 2015 proposals due this Saturday. I hope that this
Manifesto is useful for us to see why we need BMI urgently.

The Brain Principles Manifesto
(Draft Version 3.0)
Feb. 25, 2015
Historically, public acceptance of science was slow.For example, Charles
Darwin waited about 20 years (from the 1830s to 1858) to publish his
theory of evolution for fear of public reaction.About 20 years later (by
the 1870s) the scientific community and much of the general public had
accepted evolution as a fact. Of course, the debate on evolution still
goes on today.
Is the public acceptance of sciencefaster in modern days?Not necessarily
so, even though we have now better and faster means to communicate.The
primary reason is still the same but much more severe—the remaining open
scientific problems are more complex and the required knowledge to
convincingly understand goes beyond a typical single person.
For instance, network-like brain computation — connectionist computation
— has been long doubted and ignored by industry.Kunihiko Fukushima
introduced /Convolutional deep/ networks by at least 1980.Weng, Ahuja
and Huang published /Max-pooling/ in deep and fully automatic learning
networks by 1992.However, Apple, Baidu, Google, Microsoft, Samsung, and
other major related companies did not show considerable interest till
after 2012.That is a delay of about 20 years.The two techniques above
are not very difficult to understand. However, these two suddenly hot
techniques have already been proved obsolete by the discoveries of more
fundamental working principles of the brain.
Industrial and academic interests have been keen on a combination of two
things — easily understandable tests and major companies are
involved.However, the newly known brain principles have told us that the
ways to conduct such tests will give only vanishing gains that do not
lead to a human-like zero error rate, regardless how many more images
can be added to the training sets and how long the Moore’s Law can
continue. Why?This is because all these static training sets prevent
participants from considering autonomous object segmentation.The neurons
in human babies learn to segment objects through baby’s interaction with
the real physical world.Do our industry and public need another 20
years?Or more?
October 2011a highly respected multi-disciplinary professor kindly
wrote: “I tell these students that they can work on brains and do good
science, or work on robots and do good engineering.But if they try to do
both at once, the result will be neither good science nor good
engineering.”How long does it take for the industry and public to accept
that the pessimisticview of the brain was no longer true even then?
The brain principles that have already been discovered could bring
fundamental changes in the way humans live, the way countries and
societies are organized, our industry, our economy, and the way humans
treat one another.
The known brain principles have told us that the brain of anybody,
regardless of his education and experience, is fundamentally
shortsighted, in both space and time.Prof. Jonathan Haidt documented
well such shortsightedness in his book “/The Righteous Mind: Why Good
People Are Divided by Politics and Religion/
<http://www.amazon.com/The-Righteous-Mind-Politics-Religion/dp/0307455777>”,
although not in terms of brain computation.
In terms of brain computation, the circuits in your brain self-wire
beautifullyand precisely according to your real-time experience (the
genome only regulates) and their various invariance properties required
for abstraction also largely depend on experience.Serotonin (caused by,
e.g., threats), dopamine (caused by e.g., praise), and other neural
transmitters quickly change the way these circuits work so that neurons
for more long-term thoughts lost in competition to fire.Therefore, you
make long-term mistakes but you still feel you are right (e.g.,
indignant and patriotic). Everybody is like that, including every
politician.Depending on experience, shortsightedness varies in terms of
subject matter.
Surprisingly, to understand how the brain works requires a sophisticated
automata theory in computer science. See J. Weng, /Brain //as//an
Emergent Finite Automaton: A Theory and Three Theorems/
<http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CCAQFjAA&url=http%3A%2F%2Fwww.scirp.org%2Fjournal%2FPaperDownload.aspx%3FpaperID%3D53728&ei=21rnVP7fB4KZyAT-noH4Cg&usg=AFQjCNEzHz-YDhivI1esDtgKg84SEx4RuQ&bvm=bv.86475890,d.aWw&cad>,
/IJIS/, 2015, which proposed the following brain principles:
1.The developmental program (genome-like, task-nonspecific) regulates
the development (lifetime learning) of a task-nonspecific “brain”
network (DN).The DN is of general-purpose—can learn any body-capable
tasks, in principle.
2.The brain’s images are naturally sensed images of cluttered scenes
where many objects mix.As a child learns to see, teachers do not draw a
bounding box around each learned object in her retinal image — DN
self-learns segmentation.
3.The brain’s muscles have multiple subareas where each subarea
represents either declarative knowledge (e.g., abstract concepts such as
location, type, scale, etc.) or non-declarative knowledge (e.g., driving
a car or riding a bicycle).
4.Every area in the “brain” DN emerges (not statically exist) using a
unified area function whose feature development does not have local
minima in the function’s high dimensional, nonlinear, and non-iterative
approximation.
5.The “brain” DN learns incrementally—taking one-pair of sensory pattern
and motor pattern at a time to update the “brain” and discarding the
pair immediately after. Namely, a real brain has only one pair of
stereoscopic retinas.
6.The “brain” DN is always optimal—every DN update at real time realizes
the maximum likelihood estimate of the “brain”, conditioned on the
limited computational resources and the limited learning experience in
its “life” so far.
The logic completeness of a brain is (partially, not all) understood by
a universal Turing Machine in DN which is like our modern-day computer,
in principle.This automaton brain model proposes that each brain is an
automaton, but also very different from all traditional symbolic
automata because it programs itself—emergent.No traditional automata can
program themselves in the sense of Turing Machine but a brain automaton
does.
The automaton brain model has predicted that neural circuits dynamically
and precisely record the statistics of experience, roughly consistent
with neural anatomy (e.g., Felleman & Van Essen, /Cerebral Cortex/,
1991). In particular, the model predicted that “shifting attention
between `humans’ and `vehicles’ dramatically changes brain
representation of all categories” (J. Gallant et al. /Nature
Neuroscience/, 2013) and that human attention “can regulate the activity
of their neurons in the medial temporal lobe” (C. Koch et al. /Nature/,
2010). The “place” cells work of the 2014 Nobel Prize in Physiology or
Medicine implies that neurons encode exclusively bottom-up information
(place). The automaton brain model challenges such a view: Neurons
represent a combination of both bottom-up (e.g., place) and top-down
context (e.g., goal) as reported by Koch et al. and Gallant et al.
Unfortunately, the automaton brain model implies that all
neuroscientists and neural network researchers are unable to understand
the brain of their studies without a rigorous training in automata
theory. For example, traditional models for nervous systems and neural
networks focus on pattern recognition and do not have the capabilities
of a grounded symbol system (e.g., “rulefully combining and
recombining,” Stevan Harnad, /Physica D,/ 1990).The automata theory
deals with such capabilities. Does this new knowledge stun our students
and researchers or guide them so their time is better spent?
Understanding brain automata would enable us to see answers to a wide
variety of important questions, some of which are raised below. We do
not provide yes/no answers here, only raise questions.The automaton
brain model predicts that there is no absolute right or wrong in any
brain but its environmental experiences wire and rewire the brain.
In each question of social science, we may have two sides, Side A with
more knowledge due to the relatively more open political and ideological
environment and Side B with less knowledge due to relatively less open
political and ideological environment, but all having normal human
brains that deserve respect.Is it more scientifically productive for
Side A to make friends with Side B so that Side B is not threatened and
resist?Side A wants the brains in Side B to rewire for good instead of
for bad, doesn’t it?
How can our industry and public understand that the door for
understanding brains has opened for them?How can they see the economical
outlooks that this opportunity leads them to?
How should our educational system reform to prepare our many bright
minds for the new brain age?Has our government been prompt to properly
respond to this modern call from the nature?
How should our young generationact for the new opportunity that is
unfolding before their eyes?Is a currently narrowly defined academic
degree sufficient for their career?
How can everybody take advantage of the new knowledge about his own
brain so that he is more successful in his career?
We are from all walks of life and from all regions of the world.At
present, not all of us understand the scientific underpinnings of the
material in this Manifesto, just like the public of Darwin’s
time.However, these issues are relevant to the future of our nations and
our lives.We declare to form the Brain Principles Society, in order to
promote human communication and understanding of brain principles and
their implications to human societies so as to improve the quality of
life for all human beings, regardless where they are on this planet. We
are all governed by the same set of brain principles.
