Hi Antonio,
You suggested to include two main
aspects:
------
1) the channels used to transfer
information are created/selected by evolution (artificial or
natural)
2) the absolute validity of IDSO is limited
to open systems (e.g. organisms, robots, societies) living in an fast, ever
changing environment (since the need for information to be captured and used by
the agent depends on how fast the environment change) when the cost of
storing/processing information is ZERO. When the cost of storing/processing
information is not zero, then evolution might find other driving forces that
contrast the increase of information transfer.
------
The first aspect is already treated - see
points (1)-(4) in my previous
message.
The second aspect is questionable in your
current formulation. The cost of storing is never zero. The point is that the
flow of information structures the agent (e.g., changes its sensors' layout,
couples its actuators differently, partitions its memory into new states, etc.).
You see, information doesn't have to be stored as a memory structure: e.g., a new sensor
layout (or a new way to couple actuators) is "driven" by
information-flow too!
Let's
discuss this further as a
specific topic, including long-term memory and short-term memory - I must confess I don't fully understand this
short-vs-long distinction.
Cheers,
Mikhail

To summarise, I think that IDSO should be
reformulated in order to
include two main aspects:
1) the channels used to transfer
information are created/selected by
evolution (artificial or
natural)
2) the absolute validity of IDSO is limited
to open systems (e.g.
organisms, robots, societies) living in an fast, ever
changing
environment (since the need for information to be captured and used
by
the agent depends on how fast the environment change) when the cost
of
storing/processing information is ZERO. When the cost
of
storing/processing information is not zero, then evolution might
find
other driving forces that contrast the increase of
information
transfer.
If the information transfer is maximised, and the
memory (i.e.
capacity to store raw information) is limited or costly, then
the
capacity of an agent to use the experience from the past is
limited.
If by chance, a certain environmental conditions re-appears after
a
long time, then the organism cannot react using the
information
accumulated in the past.
In my opinion, even in the genotype there
is a long-term memory and
short-term memory, whose proportion are established
by evolution. IDSO
account for the short-term memory, where "fresh" data
coming from the
environment is overwritten as fast as the environment
changes.
sorry to put so many things
together...
