in Pattern Dynamics

- How can a pattern "tends to continue into the future". By what mechanism
or criteria do they "tend" to survive.
- Survival of the fittest?
- Random chance?
- Who's your daddy?
- Patterns are created by some process or algorithm. Looking at the pretty
pictures might be nice but how does that create meaning when the patterns
are the "result" not the source.
- Even when a pattern is created from a source pattern (as in the Life game),
it is the algorithm that creates the new pattern from the old pattern not
the old pattern itself.
- You say that if "continuance over the long-term is reasonably well-predicted
by continuance in the short-term" then there is "continuous pattern-sympathy".
- What criteria determines "short-term continuance". Is this criteria not
the predicate for the continued existence of the pattern rather than the
pattern itself?
- Ray Kurzweil says that there will be a singularity by the year 2025-2030
by showing the exponential growth in many things over the past number of
years but he doesn't say how it will be made to happen.
- He certainly doesn't say that he will be part of making it happen.
- He doesn't even give the motivation for why people are likely to fulfill
his extrapolation.
- Talking about the end result as if it had it's own volition, without regard
for how you are to get there, doesn't make much logical sense to me.
- The word "sympathy" I understand. The word "pattern", I understand. I
(a human) can sympathize with something or someone. How can a pattern (a
non living entity with no physical presence) sympathize with anything?
- You say "pattern in each one of the minds "wants" to perpetuate itself".
- What does it mean for a pattern to "want"? Is this not the same as saying
my fork wants to pickup food and put it in my mouth?
- I could design an algorithm that could have a goal that could be anthropomorphized
as a "want" but a pattern is the leaf, "the end result", "the picture that
is the result of".
- You equate "compassion" to "patterns in my mind are compassionate toward
their clone or near-clone" but people are compassionate all the time with
people who are very different from themselves.
- Many people have compassion for others that think, act, and have a totally
different culture than themselves.
- Could it be that some people have a desire to see themselves as "good"?
- Why couldn't being compassionate towards others just be a manifestation
of proving to yourself that you are "good".
- Many people will say that their "compassion" for someone else was fulfilling
even if the net result of their compassion was zero for the other person.
- I think compassion has nothing to do with the person who is the recipient
of the compassion and totally about the person who wants to feel it.
- You say that there are other reasons for compassion (like familiarity)
but I have seen compassion many times where the person giving has no apparent
connection to the recipient at all.
- Many people are very compassionate to animals that are not even theirs.
How do explain that in terms of similar patterns?
- Does the frequency of a pattern determine it's value?
- If you make 10 weak arguments and I make 1 really weighty argument, do
your arguments automatically win because you made more of them?
- When diamonds are mined, which is there more of, the kimberlite or the
diamonds?
- If you give value to something because there is more of it, would you
throw out the diamonds and keep the kimberlite?
- You say "natural selection, at bottom, is nothing other than a particular
instance of the general phenomenon of continuous pattern-sympathy.".
- Whether a pattern actually makes a better "fit" in it's environment has
nothing to do with "natural selection"?
- I guess there is a "general phenomenon" that the winner in a "to the death"
fight might get to produce more offspring and the loser definitely doesn't.
Is this what you mean by "continuous pattern-sympathy"?
- Natural selection is the idea that if something gives an advantage to
an organism that results in it's greater genetic propagation then in the
long run that organism will persist in that ecological niche where it's
competitor might not..
- If you want to call that change (advantage) a pattern that's ok but it
is totally contextual. The same pattern might fail hopelessly 10 feet to
the right. The value of the pattern cannot be extricated from it's context.
It also might lose tomorrow if a better pattern comes into this context
and out competes the first pattern. The pattern by itself has no special
value.
- You say "long-term survival of the short-term survivors," which is totally
obvious but misleading.
- Your can't have long term survival without short-term survival but the
reserve is definitely not true.
- If it was, then no species would ever go extinct.
- If we had species A and B that are now alive. You would have to say that
in the short term (the next 1 minute or 1 second etc) they would both still
be alive.
- Given that you say that the short-term continuance is a predictor of the
long-term continuance then it would follow that both A and B would exist
in the long run.
- Genes don't "want" to propagate themselves into the future.
- Genes or "patterns of genes" or "groups of genes" have no volition.
- Their being propagated into the future is a consequence of them winning
the fight.
- They don't even "know" who or what they are fighting. The "fight" comes
down to the fact that if organism A acquires the needed resources of organism
B then they are simply unavailable to sustain organism B.
- You say "phenotypic pattern that has persisted itself over time".
- You anthropomorphize a pattern as if it was a person.
- The successful "phenotype pattern" is the consequence of a successful
battle.
- But the battle was not waged by the pattern, rather it was waged by the
process of natural selection which derives from the fact that real matter
can't exist in two organisms at the same time.
- You wrote "Compassion itself, as a trait of organisms, is a particular pattern
that spreads exponentially according to the logic of continuous pattern-sympathy.
And it spreads faster than would be predicted via looking at gene-level dynamics
alone."
- How can a concept like "compassion" which is an idea made up in the minds
of humans have anything to do with our genes? Do you have any scientific
data to show that "any idea" people invent has anything to do with (is derived
from) their genetics? I have seen no such data myself!
- I believe myself to be compassionate but I don't see any exponential spread
of compassion. If it's spread was exponential then all persons on Earth
would already by compassionate and I don't see anything like that out there.
- Compassion is seen most often in people who are not just concerned with
their own well being. Most people are definitely NOT like that.
- You say "[compassion] emerges naturally from natural selection" but I see
exactly the opposite.
- Natural selection is most often not compassionate at all. When it looks
that way on the outside, we investigate that odd occurrence because we don't
expect it at all.
- We normally find a reason for the "apparent" compassion which shows why
the "pattern" is beneficial to both parties. For the one's we haven't found
the reason, we just haven't found it yet.
Conclusion:
I think gardeners think of the world in terms of plants and how they feed
people etc. They would probably define "compassion" using the gardening terms
that they know. Ben Goertzel, IMHO, has defined evolution and "compassion"
in terms of his mistaken belief in a "swirl of patterns" creating intelligence
all by itself. I think he is wrong about compassion and wrong about "dynamic
patterns" or "emergent patterns" creating any useful intelligence.
Some would argue that our existence is proof that intelligence can be created
from non-intelligence by this method. Our brains are a grouping of many specialized
and general purpose neural nets. We have evolved over the last 2 billion years
with unimaginable physical contexts that have molded us into what we are.
Is it possible to build a neural net (large enough) and duplicate this environment
(all the diverse environments of humans and all of the environments of our
pre human ancestors) in any reasonable time scale? The bigger question is
"Is this the quickest way to get to intelligence created with today's technology?".
I believe that it might be possible to create an artificial brain by duplicating
the neural network of the brain and then teaching and nurturing that AI for
next 30-100 years. Even if we could build the machine physically, we don't
know exactly how to teach it as we teach our own kids. The end result however,
would be hardly better than a human's brain and full of the flaws that plague
human thinking. (Lack of focus, faulty memory, slow cycle time, etc) Why would
such a machine have an easier time increasing it's intelligence as compared
to a human when it would have inherited our bad as well as good thinking memes?
We already have 6 billion brains on the Earth so why create a brain that is
no better than what we already have lots of?
Neural nets have their place but even when they work, you never get the reason
or the logic flow of why! This is not a problem if the neural net is used
for pattern extraction in video images, sound extraction, character and hand
writing recognition etc. All that matters is that we get the end result, not
how we get there. This is not true for most other kinds of problems.
Evolutionary algorithms have a place but creating appropriate success functions
for each generation has only limited usefulness in some class of problems.
Agents that can interact with each other also have a useful purpose. If I
was running a simulation of a group of people and I wanted to model the interaction
of that group on a subset of human properties, I might create that model using
agents. However, most other classes of problems don't lend themselves to the
agent metaphor.
The path to intelligence will not happen on it's own. It will only happen
if we make it happen. No amount of processing regardless of how smart the
algorithms are, will unlock the secret of intelligence without injecting vast
amounts of information and using a multitude of different techniques. This
has been proven (at least to some degree) by the failure of all the AI projects
to date.
It could be that some form of "evolutionary" programming will help with creativity.
However, humans rarely need to be creative to be considered "smart".
I feel the best way forward is to create a system that makes models and abstracts
those models so that algorithmic solutions that are successful in one context
can be experimentally tested and/or used automatically in other contexts.
These algorithms would have to be programmed by a human for the first long
while but most of us don't create totally original ideas either. Most of our
original thinking is using an existing idea in a new context or using an original
group of existing ideas in a new context. This could be done for an AI. The
idea of making an AI that has information grounded in reality is a good thing.
However, if the intelligence of a person was limited to only what we could
acquire with our own two hands, we would not be very smart at all. The idea
that you could have a "human plus" intelligence without a massive database
of real world information doesn't hold up to what we see in people. We don't
believe anyone is very smart unless they can hold a meaningful conversation
that entails much existential information. I don't think that just a huge
amount of information by itself will make the AI but I can't see how any AI
could be made without it.
The core of the AI must be able to accommodate many different kinds of techniques
and integrate them into a whole so that they can be useful. One way just won't
work.
