Creating “infant” AI: Natural thinking mimicking

Слайд 2

The two waves of AI and the winter between them

Wave 1: knowledge

The two waves of AI and the winter between them Wave 1:
base + production rules
similar to the real brain machinery
no automatic learning from data and natural texts
knowledge processing is based on first order logic – unlike the natural brain

Wave 2: deep learning
differentiability => automatic learning from data
fitting a curve through the backprop is pretty far from what the brain does – not able to implement real cognition

Declarative (semantic) memory - analogous to LTM
Generalization mechanics
Stochastic reinforcement learning
Thinking by analogy mechanics

Declarative memory

Grammar synthesizer

Sensory input

Knowledge is an undirected cyclic graph of ensembles
Basic entity ensembles

are formed from “infant” sensory input, visual and audial
v:duck a:duck
Episodes in the life of the “infant” form ensembles, connected with entities
v:Mom a:duck v:duck – Mom is showing a Duck toy saying “Duck”

Generalization mechanism

Generalization is based on Hebbian learning with frequent patterns
Frequently activated ensembles

Generalization mechanism Generalization is based on Hebbian learning with frequent patterns Frequently
capture adjacent neurons and form “twin” ensembles. They reconnect with the same ensembles becoming a “hub ensemble”

ask the “infant” questions
A question ignites an urge to be satisfied by a dopamine injection (hedonistic synapse learning)
Ensebles consist of many circuts – each circut corresponds to a combination of input ensembles and an output ensemble
The goal is to find and engrave the optimal pathway from input circuits to output circuits – the way to dopamine

Input circuits

output circuits

right pathway
Their “hub” counterparts are ignited along the way and engrave the right path on “abstract” level
Reinforcement learning on episodes “Cow say moo”, “Duck say quack”, “Cat say miau” turns into the ‘Animal say animal sound” engram
Which will produce a correct answer for “What dog say?” if “Dog” is correctly attached to the “Animals” hub ensemble

moo

Cow

episode

say

Animals say hub

animals

say twin

Where is it all going?

Basic milestones of developement:
Ability to answer any complex

Where is it all going? Basic milestones of developement: Ability to answer
question
Ability to gain knowledge from real texts, say from Wikipedia. Tons of algorithms needed
Ability to solve math tasks.
