What is Artificial Intelligence?

Generally speaking, Artificial Intelligence is a computing concept that helps a

machine think and solve complex problems as we humans do with our intelligence.

For example, we perform a task, make mistakes and learn from our mistakes (At

least the wise ones of us do!). Likewise, an AI or Artificial Intelligence is supposed

to work on a problem, make some mistakes in solving the problem and learn from

the problems in a self-correcting manner as a part of its self-improvement. Or in

other words, think of this like playing a game of chess. Every bad move you make

reduces your chances of winning the game. So, every time you lose against your

friend, you try remembering the moves you made which you shouldn’t have and

apply that knowledge in your next game and so on. Eventually, you get better and

your precision, or in this case probability of winning or solving a problem

improves by a noteworthy extent. AI is programmed to do something similar to

that!

Artificial Intelligence vs Traditional Robotics

When we hear the word “Robot”, an image of a metal box with creepy eyes and

speaking in a mechanical voice pops into our head. I mean that’s what we have

been watching in television for years, isn’t it? And to a certain degree we are right.

Traditional robotics has been perceived by pop culture as an arena that creates

humanlike machines to work for us as saviours and sometimes as super-villains

bringing in a cascade of tyranny into the human world. However, real life robots

aren’t as humanlike as we want them to be, yet. They are programmed in a specific

way to only execute tasks that it has been programmed to perform.

Imagine a self-driving car that has been designed to drive you on its own according

to where you instruct it to take you. Now for a traditional robot, the car is going to

go through the exact road that it was programmed to select for a certain destination

by its creators, possibly without the knowledge of traffic and cause accidents.

However, a human driver would have chosen the shortest path or check which

paths have the least traffic today and would be the most convenient path for that

particular destination. That is the exact humanlike creative thinking the traditional

robots lack! They are fixed in their own “not so smart” way and are largely

dependent on the program they are built on and the instructions that they are being

given. If a certain instruction doesn’t coincide with their program, the robot won’t

even be able to run, let alone going the extra step of being creative. This is the

limitation of traditional robots Artificial Intelligence is being developed to

overcome. Unlike the conventional “bips and bops”, a good AI will simulate the

complicated and intuitive sense of thinking and problem-solving abilities of the

human mind.

A Brief History of AI

The concept of Artificial Intelligence is not as modern as we think it is. This traces

back to as early as 1950 when Alan Turing invented the Turing test. Then the first

chatbot computer program, ELIZA, was created in the 1960s.[1]IBM deep blue was

a chess computer made in 1977 beat a world chess champion in two out of six

games, one won by the champion and the other three games were draw.[2]

In 2011, Siri was announced as a digital assistant by Apple. [3]

Elon Musk and some others founded OpenAI in 2015.[4][5]

Artificial Intelligence vs Machine Learning vs Deep Learning

Up until now in this article we were discussing about Artificial Intelligence as a

process that is going to help machines achieve a humanlike mental behaviour. AI is

a vast and growing field which also includes a lot more subfields like machine

learning and deep learning and so on. Machine learning is in a nutshell the concept

of computers learning to improve their predictions and creativity to resemble a

humanlike thinking process using algorithms. Machine learning involves a number

of learning processes such as:

Supervised learning: Supervised learning is a process where our machines

are designed to learn with the feeding of labelled data. In this process our machine

is being trained by giving it access to a huge amount of data and training the

machine to analyze it. For instance, the machine is given a number of images of

dogs taken from many different angles with colour variations, breeds and many

more diversity. So that, the machine learns to analyze data from these diverse

images of dogs and the “insight” of machines keep increasing and soon the

machine can predict if it’s a dog from a whole different picture which was not even

a part of the labelled data set of dog images the machine was fed earlier.

Unsupervised learning: Contrary to the supervised learning, the

unsupervised learning algorithms comprises analyzing unlabelled data i.e., in this

case we are training the machine to analyze and learn from a series of data, the

meaning of which is not apparently comprehendible by the human eyes. The

machine looks for patterns and draws conclusions on its own from the patterns of

the data. Important thing to remember that the dataset used in this instance is not

labelled and the conclusions are drawn by the machines.

Reinforcement learning: Reinforcement learning is a feedback dependent

machine learning model. In this process the machine is given a data and made to

predict what the data was. If the machine generates an inaccurate conclusion about

the input data, the machine is given feedback about its incorrectness. For example,

if you give the machine an image of a basketball and it identifies the basketball as a

tennis ball or something else, you give a negative feedback to the machine and

eventually the machine learns to identify an image of a basketball on its own when

it comes across a completely different picture of a basketball.

Deep Learning, on the other hand is the concept of computers simulating the

process a human brain takes to analyze, think and learn. The deep learning process

involves something called a neural network as a part of the thinking process for an

AI. It takes an enormous amount of data to train deep learning and a considerably

powerful computing device for such computation methods.

AI at Work Today

The most common examples of uses of Artificial Intelligence can be found today

in smart personal assistants like Apple’s Siri and Amazon’s Alexa. People interact

with these devices to command them on a daily basis and these devices use the

commands as a part of their dataset to learn from. Another known example of

Artificial Intelligence is the use of algorithms in Netflix. Netflix provides very

much accurate and relevant suggestions of movies, tv series from our data which is

created every time we stream or click on something in Netflix. As the dataset for

these systems grows, their accuracy and precision increase as well. Artificial

Intelligence is also viewed as a great tool for better cybersecurity. Many banks are

using AI as a means to identify unauthorized credit cards uses. From analyzing

complex genetic data to perform the most delicate surgeries at the highest precision

is also being worked on to integrate with AI. We all know about companies like

Tesla and Apple working to make flawless self-driving cars which is going to have

game changing impacts on the future of transportation.

Concerns about AI

One of the most immediate concerns about Artificial Intelligence is the fear of

losing jobs. Artificial Intelligence enhancing automation is also causing huge job

losses around the world. According to a Forbes article, it is predicted that by 2025

automation will cause a loss of 85 million jobs. [6] Bigger fears regarding AI

includes the scenario whereas machines become smarter and smarter they going to

end up being as opinionated and biased like some of the people training it.

Automatization of weapons is also a big reason people worry about the future of

Artificial Intelligence. The idea that weapons can be used to search and target

someone with pre-programmed instructions and the misuse of this by governments

or mafias or rogue AI can be something very deadly and devastating. However,

there are many myths in disguise of concerns surrounding AI that spreads panic

and misinformation. AI today is nowhere near to become a super-intelligent entity

and turn into our overlords like in sci-fi movies. However, heavy regulations and

cautions are being advised by Big Tech giants like Elon Musk while developing

this industry.

Artificial Intelligence and The Future

It is said that AI is the greatest thing humankind has ever worked on. AI is being

used in image and speech recognition and analysis which will be far better than

human recognition of image and speech and its application stretches wide and far.

There are research and works being conducted using AI that is going to play a very

important role in our future healthcare. AI is being worked on to cure Alzheimer’s

disease and someday even blindness. Someone with dyslexia is being helped to

read better with the help of AI. Genetic data is being analyzed by bioinformatics;

data science integrated with AI for way better data analysis in healthcare that has

not been possible for us in the past. Fields like cancer research and other such

diseases are being impacted greatly by advanced applications of AI. AI can be a

great tool in the future of education. AI can be used to analyze data from an

individual’s personal and intellectual needs, capabilities, choices and limitations to

develop customized curriculum, strategies and schedules that will be more well

suited, appealling and inclusive of most, if not all, children and adults. The uses of

AI are also going to change the way we are going to commute in the future. In

addition to self-driving cars, work is being done to manufacture “self-flying”

planes and drones that conveniently deliver your food faster and better. One of the

biggest concerns about AI is that jobs are being replaced due to automation.

However, AI might be creating more jobs than it replaces. This will change the

way humans work by creating new types of jobs.

AI is still in a fairly preliminary (but rapidly growing) stage today and it requires

more and more training to develop. Trainers, engineers, system designers and

software developer jobs in machine learning, data science and many such related

fields are being created in abundance. New business and investment opportunities

are also on the rise due to endless AI applications in agriculture, education,

transportation, finance, biotechnology, cybersecurity, gaming etc. As new

businesses are being created so are new jobs. Many existing jobs are becoming

redefined and more specialised which is really important for the new world to

prosper and advance.

Towards Conclusion…

The growth of Artificial Intelligence in recent times has been exponential. We

cannot even imagine how big and impactful AI is going to be in the near future and

how drastically it is going to change and upgrade the world we live in today. There

are a lot more to learn about AI and its rapidly growing applications in our life. I

believe it would be wise to adapt to this changing world and acquire skills related

to Artificial Intelligence and technology. Just like AI learns and develops, we

should too - to make this world a better place
