10 Subconscience –
memory's own life
The automaton's memory is the union of various neuronal
ensembles. The main volume of memory is occupied by EW's and by
ensembles-phrases, which correspond both to the objects and situations
in the outer world, and to the concrete and abstract notions about the
properties of the world. The main property of the automaton, leading to
the intellectuality, is the limitation of memory capacity. The outer
world is infinitely diverse in its details, therefore the automaton is
unable to remember all details and correct reactions to them.
Consequently, the automaton must switch from the remembering of
concrete situations to the discovering and remembering of regularities,
and then to the generalized ideas and abstractions. The generalization
problem in the neuroenergetic concept is solved as a problem of
minimization of the number of ensembles by the following logic:
1. The conductivities of excitatory links in the absence
of generation gradually decrease. Consequently, the condition for
existence of ensembles is their periodic activity, preventing the
conductivities from decrease below some least ones. Minimal value of
conductivity should allow the ensemble to bootstrap by LF-generation of
small part of its neurons, i.e., to realize the event RiÞSi. There is a
certain time interval T, during which the conductivities decrease from
normal values to the minimal ones in the marked sense. Thus, to exist,
each ensemble must work at least once within the interval T. Total
memory capacity (the automaton's vocabulary) is divided into two parts:
active and passive. Active vocabulary EW's work more often, than with
the frequency 1/T. At the same time, passive vocabulary EW's in the
given period of the automaton's life do not get in the groups {Si} at the moment t2 and do not recover their internal links. Therefore,
the automaton has a problem of passive vocabulary saving.
2. Excitability of the ensemble, i.e., probability of the
event RiÞSi,
depends on many factors, and on the age q
of the ensemble's neurons. The increase of q
for the passive vocabulary EW's may be the cause of their activity and
recovery of links, if their neurons will not generate spikes due to
some other reasons. As it was marked, the automaton has two main modes
– sleep and awaking. During the awaking phase there is no significant
decrease of q for the passive vocabulary
EW's, because they are permanently blocked by the functioning of active
vocabulary EW's. In the sleep phase the passive vocabulary EW's neurons
(at least, their HF-generations) are blocked by activity of MAG's. The
cause of this is that neurons, not participating in associative memory,
compose the greater part of neural network, and therefore they form a
lot of inhibitory links to the neurons of memory ensembles.
3. The automaton must have a special state, providing
regeneration of the passive vocabulary, i.e., neither sleep nor
awaking. Neurons in this special state should be excited mainly owing
to the great q values. This third state
(subconscience) in the automaton is provided by separation of the
initial neural network onto the weakly interconnected parts –
"semi-nets", so that one semi-net can awake while another still sleeps.
Subconscience appears in the awaked semi-net – this is a memory's "own
life" mode, i.e., the mode of autonomous living, without modulating
influences from EC and without excitation U from receptor systems. EC,
motor and receptor systems in this state are blocked by strong rhythmic
generation, produced by MAG's queue of sleeping semi-net. Subconscience
occupies a small time and may be compared to the state of fast
(paradoxical) human sleep. The queue of passive vocabulary EW's for
recovering moves just in the state of subconscience. During one period
of subconscience only small part of the queue has time to work. The
whole queue must have acted for time, less than T. It is this
requirement that restricts the automaton's memory capacity.
4. Recovering of EW's in subconscience takes place at
HF-generations, that is possible only at strong associative aid from
many EW's. Memory's own life is the formation and struggle of various
groups of ensembles, the search for the allies and the supplanting of
opponents, which are outlined by the automaton's experience, reflected
in the mosaic of associative links. As a result of active memory's own
life, new associative links and new ensembles are formed in the
subconscience. This is the real introduction into the intelligence. The
appearance of new associative links and new ensembles is the alteration
of a world model, appearing because of accumulated experience
processing, not as a result of direct experience. Physiological
optimization of relations in memory during the subconscience state
tends to transform into the logical optimization of knowledge
structures, leading to their generalization. When the automaton will
awake, it will search in the external environment for the confirmation
of its new ideas, and either will confirm and fix them, or will reject
them. New ideas, appearing "from within", are the intuitive ideas, and
the mechanism of formationof the corresponding memory structures is the
intuition mechanism.
5. Priorities of ensembles in the subconscience are
defined not only by the age queue, but also by dominants, i.e., by
active vocabulary EW's, corresponding to hard tasks, which weren't
solved by the automaton in the nearest past. This means, that these
dominants with a great probability will be centers of mutual aid unions
in the subconscience state, and in subconscience the automaton will
continue to solve its problems. In the state of subconscience the
influences from environment don't disturb the automaton, and at the
same time the very distant and indirect analogies from various areas of
experience are accessible for the automaton.
6. In subconscience the automaton looks for the new, more
simple and general solutions of various external problems and, if it
finds such solutions, it forms new memory structures for them. Activity
of new structures blocks the activity of old ones for the same problem,
both in awaking and in subconscience. A new structure does not permit
to renew for an old one, and supplants it from memory, releasing space
for the next knowledge. This is the mechanism of solution of the
automaton's memory minimization problem.
