Subject: Advantages of Lamarckian evolution?
Date: Thu, 17 Sep 92 12:32:12 PDT
A comment about artificial Lamarckian evolution on another
forum intrigued me into writing the following response:
> While it's certainly conceivable to design a self-reproducing
> machine that inherits acquired characteristics (consider the
> self-reproducing program that disassembles its running core image),
> but I don't see why you'd want to build one.
It adds another feedback loop to the search algorithm that is
evolution. For example, if that core contains the password file,
it might be very beneficial to an evolving network worm if it
incorporates that information into its and its descendants' code.
Under a non-Lamarkian genetic algorithm the baby worm has to build
its own password files from scratch. On the other hand, if password files
change too quickly, the genetic code could become too bulky to be useful,
so Lamarkian evolution might need to be accompanied by some purging
mechanism.
(I'd hope nobody would want to build such a thing, but the phenomenon
might be useful to humans in another context).
For a present-day biological example, think of the giraffe:
if it could have fed back its neck-stretching into its genetic
code, it would have evolved to fit its new tall-tree-leaf-eating
niche much faster.
This brings up an a-life question: I've seen combined genetic
algorithm/neural nets where the genetic algorithm does
the global search, encoding the initial weights for neural nets
which do the local search. I wonder, under what conditions
would sexually recombining with the learned weights help, and under
what conditions would it hurt? Has this experiment been tried?
(If we just fed the learned weights directly to the next generation
it would, I reckon, be no different then doing further learning
on the same net and getting rid of the genetic algorithm).

ARTIFICIAL NEURAL NETWORK
IWANN'93
Second and Final Announcement and Call for Papers
Sitges (Barcelona), Spain
June 9 - 11, 1993
SPONSORED BY
IFIP (Working Group in Neural Computer Systems, WG10.6)

UNED (Madrid)
IWANN'91 (International Workshop on Artificial Neural Networks) was held
in Granada (Spain) in September 1991. People from over 10 countries attended
the Workshop, and over 50 oral presentations were given.
IWANN'93 will be organised next June, 1993 in Sitges (Spain) with the
following Scope and Topics.
SCOPE
Artificial Neural Networks (ANN) were first developed as structural or
functional models of biological systems in an attempt to emulate their unique
problem-solving abilities.
The main interest in neural topics stems from their advantages in
plasticity, speed and autonomy over conventional hardware and software, which
have traditionally proven inadequate for handling certain tasks such as
perception, learning, planning, knowledge acquisition and natural language
processing.
IWANN's main objective is to offer a forum for achieving a global,
innovative and advanced perspective on ANN. In addition to conventional Neural
Networks aspects, such as algorithms, architectures, software development tools
, learning, implementations and applications, IWANN'93 will also be concerned
with other complementary topics such as neural computation theory and
methodology, physiological and anatomical basis, local computation models,
organization and structures resembling biological systems.
Contributions on the following aspects are welcome:
* New models for biological networks.
* New algorithms and architectures for autonomy and self-
programmability using local learning strategies.
* Relationship with symbolic and knowledge-based systems.
* New implementation proposals using general or specific processors.
Implementations with embedded learning are especially invited.
* Applications.
Finally, it is expected that IWANN'93 will also serve as a meeting point
for engineers and scientists to establish professional contacts and
relationships.
TOPICS
1 - BIOLOGICAL PERSPECTIVES: anatomical and physiological basis, local
circuits, biophysics and natural computation.
2 - THEORETICAL MODELS: analog, logic, inferential, statistical and
fuzzy models. Statistical mechanics.
3 - ORGANIZATIONAL PRINCIPLES: network dynamics, self-organization,
competition, recurrency, evolutive optimization and genetic
algorithms.
4 - LEARNING: supervised and unsupervised strategies, local self-
programming, continuous learning, evolutive algorithms
5 - COGNITIVE SCIENCE AND AI: perception and psychophysics, symbolic
reasoning and memory.
6 - NEURAL SOFTWARE: languages, tools, simulation and benchmarks.
7 - HARDWARE IMPLEMENTATION: VLSI, parallel architectures,
neurochips, preprocessing networks, neurodevices,
benchmarks, optical and other technologies.
8 - NEURAL NETWORKS FOR SIGNAL PROCESSING: preprocessing, vision,
speech recognition, adaptive filtering, noise reduction.
9 - NEURAL NETWORKS FOR COMMUNICATIONS SYSTEMS: modems and codecs,
network management, digital communications.
10 - NEURAL NETWORKS FOR CONTROL AND ROBOTICS: system identification,
motion, adaptive control, navigation, real time applications.
