A new approach to Artificial Intelligence

There are HUGE differences between brain
architecture and computer architecture
 The difficulty to emulate one system on another
system increases linear with the number of
differences in architecture between the two
systems.

The brain is an interactive information carrier.
 Computer Emulation Issues:
▪
▪
▪
▪
Making compromises in reduced neuron complexity
Simplify the thousands of connections between neurons
Simplify sensory devices (camera no match for the eye)
Learning by feedback - a computer has no hardware for
measuring timing differences between millions of input
pulses. Learning is compromised
No computer is capable of emulating the entire human brain in real time at
this present time

Blue Gene /P supercomputer:


To create this type of behavior would take
approximately 4000 times the performance of
current super-computers:
 IBM Blue Gene/P – emulation of 1.6 billion neurons
and 8.9 trillion synapses at 0.15% of real time. Ref.
IBM publication ‘The cat is out of the bag’
 IBM Blue Gene/p – emulating 900 million neurons and
9 trillion synapses at 1.2% of real time

Human brain: 88 billion neurons and an
estimated 100 trillion synapses at 100% real time

Recreating intelligence by program control
involves a fundamental error in thinking:
 The brain is not an analysis and control system
 The brain is the only intelligent entity that we know
off, consisting of memory and integrating cores
 Learning is a fundamental function of the brain
 Artificial Intelligence systems need to learn to control
rather than being programmed to control
 INTELLIGENCE is defined as the ability to acquire
knowledge and to subsequently apply this knowledge,
to combine it to form new solutions…

“Artificial Intelligence is the ability to perform
a task that would require intelligence if done
by a human being” – Minsky
We only use 10% of our brain (anonymous)
Bigger brains means smarter, and humans
have the biggest brains of any animal
We have to emulate the entire human brain
to create intelligence
A new way to do Artificial Intelligence
The brain is an interactive information carrier.
Information is stored in synapses
 Synapses are everywhere in the brain, therefore
memory is everywhere - Fundamental
 Learning is essential, it is how intelligence emerges
and how the synapses are ‘programmed’, within a
DNA-built Framework
 A digital architecture that is similar to the cells that
make up the brain, with analog synaptic parameters
expressed as multi-bit digital values
 Wired as a cortical column, a single chip contains
10,000 neurons and 500,000 synapses

Consists of digital cells and synaptic memory

A Synthetic Neuro-Anatomy will function like
the brain when its neural cell emulation is
sufficiently realistic and the network is the
same as the biological model
The model needs to operate at real-time
speed to allow learning to take place, in sync
with the real world around us
Learning is the method by which a neural
network acquires function
