Transcript Neural Networks

The brain differs from other biophysical systems it is inherently complex,
dynamic and plastic
… and it can not average effects like in other systems
One cannot ignore complexity of brain with human social environment…. The
complexity of individuals enriches the dynamics of the society of neurons…
Societies of neurons enable the group to learn to successfully function in
unpredictable environments and to create new behaviors under changing
circumstances.

Neural Networks and Perception
William James, What is Emotion, 1884
“Disembodied emotion is a physical non-entity.”
Our emotional experience occurs before and after one has had the
opportunity of cognition.
Daniel Kahneman, Thinking Fast and Slow, 2012
The experiencing self and the remembering self.
The life of 600,000,000 3-second experiences or with each saccade of
attention lasting 20-200 ms…. We must be able to unconsciously
preferentially select what will be remembered.
The recall of our memory associates the context surrounding the recall of
the memory, the relative nature of expectations and memory.

Relativity
1.Measurements
of various
quantities are
relative to the
velocities of
observers.
2. Space and time
should be
considered
together and in
relation to each
other.
3. The speed of
light is the same
for all observers.

How far have we come to understanding the brain?
“Are understanding of the brain is akin to hitting a television when a signal is
lost. It may have an effect but we do not know why. We do not know the
process. The task for this generation is develop conceptual /theoretical tools
for low-level computations to global functions.”
Cristina Domnisoru, 02.22.14 Jacobus Fellowship acceptance speech, Princeton University
Very tight interactions between theory modeling and experiments will
provide missing breakthrough in our understanding of the brain.
