Title: Cognitive Systems, ICANN panel, Q1


1
Cognitive Systems, ICANN panel, Q1
  • What is machine intelligence, as beyond pattern
    matching, classification and prediction.

Low level cognitive functions perception,
sensorimotor actions, are basically active signal
analysis (control used to get better signal)
active pattern matching (anticipation, attention,
information filtering) to recognize objects and
structures. Higher-level cognitive functions
associative and episodic memory for natural
perception, representation of complex knowledge
structures, sequential logical and intuitive
reasoning processes, problems solving, planning
and other things symbolic AI works on ... In
between? Reinforcement learning, emotions?
Intuitive computing, solving compositionality
problems search constrained by separable neural
networks.

Cognitive Systems, ICANN panel, Q2
  • How can such machine intelligence best be
    employed?
  • There are already numerous educational
    industrial applications, more are coming in home
    and office automation, cars (vision and object
    recognition, planning routes) etc. Driving in
    urban environment requires some pre-symbolic
    reasoning.
  • We need a detailed roadmap with progressively
    more difficult tasks
  • what has been already done and may be integrated
    in other models to avoid duplication of work
    (although sometimes it is useful), may be used in
    applications improved sound/object
    localization, orientation mechanisms, control,
    recognitions of speech, gestures, lip movements,
    face recognition, person identification, etc
  • what is doable in relatively short time some
    emotions, object recognition, attention control
  • what is difficult neural approach to higher
    mental functions?

Cognitive Systems, ICANN panel, Q3/4
  • How is intelligence actually achieved in the
    human brain (for example as related to recent
    researches on the capacity and power of human
    working memory)?
  • Depending on the level.
  • Perception, motor control good models of some
    functions.
  • Higher cognitive functions - no one really knows?
  • How is reasoning achieved without language?
  • General idea at the base level, spreading
    activation networks, particular configuration of
    activation distributions represents the object at
    microlevel
  • different hierarchical levels of search,
    left/right hemisphere interactions interesting
    experimental data from paired word associations
    and solving problems requiring insight.
  • General principle learning new by re-using old.

Cognitive Systems, ICANN panel, Q5/6
  • What are general simple architectures that
    support reasoning?
  • Classical symbolic SOAR, ACT-R, have large
    number of applications, although they are very
    rough approximations to brain processes.
  • Interesting connectionist architectures IDA
    (Franklin), Shruti (Shastri) and many others.
  • Comparison of some architectures in real-time
    robot control applications would be useful.
  • How can we implement primitive levels of
    reasoning as are observed in crows and
    chimpanzees?
  • Animal reasoning is pre-symbolic, so first
    sensorimotor exploration is needed, involving
    object and motion recognition solving simple
    manipulation problems.

Cognitive Systems, ICANN panel, Q7/8
  • Does language play an essential role in the
    reasoning process (sometimes hidden)?
  • Representation of real objects and sensomotoric
    sequences in terms of activations has large
    variability, adding symbolic labels reduces
    variability in the part of activation space. This
    must influence the reasoning process.
  • How can we build a truly creative architecture to
    solve difficult tasks?
  • Ive proposed (WCCI06) to focus first on
    creation of new words, starting from description
    of products, organizations etc, simulating the
    process, as our simulations find some interesting
    words and about 2/3 words that have already been
    invented.
  • This can be extended to higher-level mechanisms,
    as in Mazursky, Goldberg and Solomon work on
    ideas for advertisement.

6
Cognitive Systems, ICANN panel, Q9/10
  • How would a reasoning system at non-linguistic
    level help in any branch of industry?
  • One example is in understanding complex
    machinery reactions, as in the refineries or
    other plants this is relatively simple and may
    be achieved using correlation machines.
  • Car driving in urban environments will need some
    reasoning.
  • What are the ethical problems thrown up by future
    advances in this area, advancing as it does
    towards the 'soul' of humanity?
  • People are very resistant to science and will
    harbor their ideas about souls and spirits
    independent of the development ...
  • Problems may arise in distant future when more
    and more jobs will be automated.
  • Conscious machines will open a Pandoras box ...

DREAM modules
DREAM project is focused on perception (visual,
auditory, text inputs), cognitive functions
(reasoning based on perceptions), natural
language communication in well defined contexts,
real time control of the simulated/physical head.
