AI systems are growing. But what is AI, where did the idea behind it come from, what is intelligence, how does expert level intelligence work, and perhaps most importantly, would AI systems eventually make human beings redundant?
1. What Really is Artificial Intelligence about?

2. Introduction
Stephen Hawking, is perhaps the most eminent
scientist alive today, so when he speaks, it’s
important to sit up and listen. In 2014, Professor
Hawking warned that: The development of (true)
artificial intelligence could spell the end of the
human race, (Cellan-Jones, Technology
correspondent, BBC).
In a follow up later this month, he is again
reported as saying that artificial intelligence
could be humanity's greatest disaster
3. Surely enough, Professor Hawking’s observations
have unleashed questions and arguments from AI
experts and non experts alike.
There is no doubt, AI systems are growing. But
what is AI, where did the idea behind it come
from, what is intelligence, how does expert level
intelligence work, and perhaps most importantly,
would AI systems eventually make human beings
redundant?

4. Providing answers to questions such as these
will require many rounds of articles. But in
these three highly simplified lecturers, I hope to
explore and share some light on them.
Those who wish to explore the subject in depth
would find at the end of each slide links to far
richer coverage elsewhere

8. A working definition of AI
Two simple words, but many different definitions:
The word artificial simply put means, a human creation as
oppose to something natural.
Artificial Intelligence is machine or computer based
intelligence as oppose to human intelligence. It refers to a
specific computer program that attempt to emulate
human cognitive ability and behaviour
The field of Artificial Intelligence is dedicated to the study
and replication of human brain in machines, thus enabling
them to perform cognitive based activities.
AI imitate human behaviour in areas of problem Solving,
Speech recognition, decision making, Learning and
Planning.
9. So what is Intelligence?
There is no universally agreed view on what constitute
human intelligence. Understanding of human intelligence is
very much a work in progress
Most definition of intelligence however, suggest that
intelligence is brain base or cognitive process performed by
individuals and machines when solving problems
But for our purpose, intelligence is simply defined as ability
to think, understand and learn. The question is can a
machine be classified as intelligent?
Later in the second part of this piece, we shall see how
expert systems perform processes such as reasoning and
problem solving
10. What is Machine Intelligence anyway
As noted in the previous slide, the term intelligence is
commonly associated with high level cognitive traits
possessed by humans and non humans alike.
Intelligence can be gleaned from cognitive behaviour or
performance of a complex task. This include task such as:
Logical Reasoning
Decision making
Problem Solving
Complex Communication
Recognition and extension of patterns
Ability to read, write and learn autonomously
11. What is Machine Intelligence anyway
A machine is said to be intelligent if it’s able to
perform some of the human functions, like,
learning, decision making and pattern recognition
12. Purpose of AI Technology
The ultimate goal of AI is to create computer programs
(algorithms) that are capable of solving complex problems,
achieve and exceed human level expertise
Experts in the field dedicate themselves to learning about
and creating computers programs that simulate thinking
and do things that would require intelligent human beings
to do.
14. How new are the concepts behind AI?
The origins of ideas behind AI and subsequent
developments can be traced back to the British
mathematician, Alan Turing.
Two of Turin’s work in particular, the imitation game,
(Turing, 1936) and computing machinery and intelligence
(Turing, 1950) help set the scene for AI Today.
From 1950 through to mid 1980s, the fundamental
questions posed by Alan Turing inspired others such as:
Warrant McCulloch and Walter Pitt in 1943 to produce the
first artificial Neuron Network
15. The invention of the stored program computer
The modern store program computer developed
by John Von Neumann and colleagues is also
based on the concepts of Artificial Intelligence
16. Who coined the word Artificial Intelligence?
The first use of the term artificial intelligence is attributed
to John McCarthy.
In 1958, McCarthy presented a paper, ‘Programs with
Common Sense’, in which he proposed a program called
the Advice Taker
He argued that advice taker could search for solutions to
general problems of the world, a precursor to search
engines and expert systems?
He demonstrated through his paper how the program
could be designed to accept new knowledge, in different
areas of expertise without being reprogrammed.

20. AI Benefits and Challenges
Possible Benefits of AI
• Taking over mundane repetitive task
• Perform complex task in a fraction of
the time it takes a human operator
to complete
• Producing outcomes that are easy to
understand
• AI machines can be deployed in
hazardous environments, thus
reducing risk to humans
• They complement human effort
• AI Systems are generally more
consistent and reliable than human
beings
Challenges and risk of AI
• Developing a thinking AI
systems are currently too
difficult to achieve in practice
• Wide spread use of AI raises
a number of ethical, moral and
legal issues that are yet to be
addressed
• Benefit of AI technologies accrue
to a few rich and wealthy owners
of investment capital
• Poses high negative impact on
traditional skills and increasing
inequality as a result
