What is Artificial Intelligence?

Artificial Intelligence (AI) is the field of computer science that builds machines and software able to perform tasks that normally require human intelligence, such as learning, reasoning, problem-solving, and understanding language, using algorithms and data. It’s all about teaching computers to learn from experiences, solve problems, and even understand and respond to human language. AI is used in many things, like self-driving cars, virtual assistants, and helping doctors make medical diagnoses.

1. History of Artificial Intelligence

The term ‘Artificial intelligence’ was coined by John McCarthy in the year 1956 at Dartmouth College at the first-ever AI conference. Later that year, JC Shaw, Herbert Simon, and Allen Newell created the first AI software program named ‘Logic Theorist.’

However, the idea of a ‘machine that thinks’ dates back to the Mayan civilization. In the modern era, there have been some important events since the advent of electronic computers that played a crucial role in the evolution of AI:

a. Maturation of Artificial Intelligence (1943–1952)

Walter Pitts and Warren S. McCulloch, two mathematicians, published ‘A Logical Calculus of the Ideas Immanent in Nervous Activity’ in the Journal of Mathematical Biophysics. They described the behavior of human neurons with the help of simple logical functions that inspired an English mathematician Alan Turing to publish ‘Computing Machinery and Intelligence’ which comprised a test. This Turing Test is used to check a machine’s ability to exhibit intelligent behavior.

b. The birth of Artificial Intelligence (1952–1956)

Logic Theorist, the first AI program was created in the year 1955 by Allen Newell and Herbert A Simon. It proved around 52 mathematical theorems and improved the proofs for other theorems. Professor John McCarthy coined the term ‘Artificial Intelligence’ at Dartmouth, and it was accepted as an academic field.

c. Golden years – early enthusiasm (1956–1974)

After the invention of high-level languages such as LISP, COBOL, and FORTRAN, researchers got more excited about AI and developed algorithms to solve complex mathematical problems. Joseph Weizenbaum, a computer scientist, created the first chatbot named ‘ELIZA’ in the year 1966. A year later, Frank Rosenblatt built a computer named ‘Mark 1 Perceptron.’ This computer was based on the biological neural network (BNN) and learned through the method of trial and error that was later called reinforcement learning. In 1972, Japan built the first intelligent humanoid robot named ‘WABOT-1.’ Since then, robots are constantly developed and trained to perform complex tasks in various industries.

d. A boom in AI (1980–1987)

The first AI winter (1974–1980) was over, and governments started seeing the potential of how useful AI systems could be for the economy and defense forces. Expert systems and software were programmed to simulate the decision-making ability of the human brain in machines. AI algorithms like backpropagation, which uses neural networks to understand a problem and find the best possible solution, were used.

e. The AI Winter (1987–1993)

By the end of the year 1988, IBM successfully translated a set of bilingual sentences from English to French. More advancements were going on in the field of AI and Machine Learning, and by 1989, Yann LeCun successfully applied the backpropagation algorithm to recognize handwritten ZIP codes. It took three days for the system to produce the results but was still fast enough given the hardware limitations at that time.

g. The emergence of intelligent agents (1993–2011)

In the year 1997, IBM developed a chess-playing computer named ‘Deep Blue’ that outperformed the world chess champion, Garry Kasparov, in a chess match, twice. In 2002, Artificial intelligence for the first time stepped into the domestics and built a vacuum cleaner named ’Roomba.’ By the year 2006, MNCs such as Facebook, Google, and Microsoft started using AI algorithms and Data Analytics to understand customer behavior and improve their recommendation systems.

h. Deep Learning, Big Data, and Artificial General Intelligence (2011–2020)

With computing systems becoming more and more powerful, it is now possible to process large amounts of data and train our machines to make better decisions. Supercomputers take advantage of AI algorithms and neural networks to solve some of the most complex problems of the modern world. Recently, Neuralink, a company owned by Elon Musk, successfully demonstrated a brain-machine interface where a monkey played the ping pong ball video game from his mind.

i. The Era of Generative AI and LLMs (2020 – Present)

The Generative AI age, with the introduction of Large Language Models, is a new era of technological revolution. Large Language Models (LLMs), which are trained on vast volumes of text, are capable of interpreting and producing human language, changing the worlds of content generation, translation, and customer support.

Why is Artificial Intelligence important?

Artificial Intelligence (AI) is important because it automates repetitive work, improves decision-making, personalizes user experiences, forecasts future trends, and improves customer service. Here are the key reasons why we need artificial intelligence:

1. Automation and Efficiency

Artificial Intelligence (AI) is capable of handling tasks that are monotonous, time-intensive, or risky for humans. This increases efficiency and productivity in sectors such as manufacturing, healthcare, finance, banking, and transportation.

2. Improved Decision-Making

AI systems improve decision-making by processing and analyzing vast amounts of data quickly. This supports better decisions better decision-making in fields like agriculture, healthcare diagnosis, financial trading, and logistics planning.

3. Personalization and Recommendations

AI-driven systems can learn individual preferences and behaviors to offer tailored experiences. Platforms such as Netflix, Spotify, and Amazon use AI to recommend content or products based on a user’s past interactions.

5. Enhanced Customer Service

AI-powered chatbots and virtual assistants are capable of providing round-the-clock customer support, answering queries, and solving problems in real time, improving customer satisfaction.

How does Artificial Intelligence work?

Computers are good at following instructions, i.e., sequences of steps to execute a task. If we give a computer steps to execute a task, it should easily be able to complete it. The steps are called algorithms. An algorithm can be as simple as printing two numbers or as difficult as predicting who will win elections in the coming year!

So, how can we accomplish this?

Let’s take the example of predicting the weather forecast for 2020.

1. Data Collection

First of all, what we need is a lot of data! Let’s take the data from 2006 to 2019.

2. Data Processing

Now, we will divide this data into an 80:20 ratio. 80 percent of the data is going to be our training data, and the rest 20 percent will be our testing data. The actual outcomes are known for all of the 2006–2019 data, so the model’s predictions can be checked.

3. Training of Model

What happens once we collect the data? We will feed the labeled data (train data), i.e., 80 percent of the data, into the machine. Here, the algorithm is learning from the data that has been fed into it.

4. Testing of Model

Next, we need to test the algorithm. Here, we feed the test data, i.e., the remaining 20 percent of the data, to the machine. The machine gives us the output. Now, we cross-verify the output given by the machine with the actual output of the data and check for its accuracy.

5. Validation

While checking for accuracy, if we are not satisfied with the model, we tweak the algorithm to give the precise output or at least somewhere close to the actual output. Once we are satisfied with the model, we then feed new data to the model so that it can predict the weather forecast for the year 2020.

6. Fine Tuning

With more and more sets of data being fed into the system, the output becomes more and more precise. Note that no algorithm can be 100 percent accurate, and no machine has attained 100 percent efficiency.

Types of Artificial Intelligence

Artificial Intelligence is commonly classified into four types based on capability: reactive machines, limited memory, theory of mind, and self-awareness.

Reactive Machines	Limited Memory	Theory of Mind	Self-Awareness
Simple classification and pattern recognition tasks	Complex classification tasks	Understands human reasoning and motives	Human-level intelligence that could surpass human intelligence
Great when all parameters are known	Uses historical data to make predictions	Needs fewer examples to learn because it understands motives	Sense of self-consciousness
Can’t deal with imperfect information	Current state of AI	Next milestone for the evolution of AI	Does not exist yet

Advantages and Disadvantages of Artificial Intelligence

1. Advantages of Artificial Intelligence

a. Reduced human error

When humans handle tasks demanding precision, errors can occur. Yet, well-programmed machines excel in executing repetitive tasks without many mistakes. They learn from past experiences, ensuring accuracy and efficiency.

b. Risk avoidance

Replacing humans with intelligent robots to do dangerous tasks is one of the biggest advantages of Artificial Intelligence. AI robots now replace humans in risky environments such as coal mines, exploring the deepest parts of the ocean, sewage treatment, and nuclear power plants to avoid any disaster.

c. Replacing repetitive jobs

Our day-to-day work includes many repetitive tasks that we have to do every day without any change. For example, washing your clothes or mopping the floor doesn’t require you to be creative and find new easy to do every day. Even big industries have production lines where the same number of tasks has to be done in an exact sequence. Now, machines have replaced these tasks so that humans can spend this time doing creative things.

d. Digital assistance

With digital assistants to interact with users 24/7, organizations can reduce the need for human staff and deliver faster service to customers. It is a win-win situation for both the organization and the customers. In most cases, it is really hard to determine whether a customer is chatting with the chatbot or a human being.

2. Disadvantages of Artificial Intelligence

a. High cost of creation

Computing hardware and software are upgraded at a rapid pace, which raises the cost of AI. Machines need to be repaired and maintained with time to keep the latest requirements in check, which needs a lot of resources.

b. No emotions

There is no doubt that machines are much more powerful and faster than human beings. They can perform multiple tasks simultaneously and produce results in a split second. AI-powered robots can also lift heavier loads, which speeds up the production cycle. However, machines cannot build an emotional connection with other human beings, which is a crucial aspect of team management.

c. Box Thinking

Machines can perfectly execute the preassigned tasks or operations with a definite range of constraints. However, they start producing ambiguous results if they get anything out of the trend.

d. Can’t think for Itself

Artificial Intelligence aims to process data and make a conscious decision as we humans do. But at present, AI can only do the tasks it is programmed for. These systems cannot make decisions based on emotions, compassion, and empathy. For example, if a self-driving car is not programmed to consider animals like deer as living organisms, it will not stop even if it hits a deer and knocks it off.

Examples of Artificial Intelligence

The goal of an AI is to make tasks easier for humans. Because of this, AI is used in many technologies today. Examples include:

1. ChatGPT

ChatGPT is a conversational AI chatbot developed by OpenAI. It works in two basic steps. First, it takes in the text input provided by the user. Then, using its profound understanding of language and context, it seamlessly generates relevant and coherent responses.

This exceptional AI tool can engage in conversations just like a human, making it a valuable virtual chat partner. Moreover, it goes beyond mere conversation. ChatGPT can perform a wide range of tasks, including coding, data analysis, and content creation. With added features and tools, it’s a prime example of AI’s ability to enhance productivity and offer diverse solutions in our increasingly digital landscape.

2. Machine Learning

Machine learning is a branch of AI that enables computers to learn from data and improve without being explicitly programmed for each task. There are three types of machine learning:

a. Supervised learning

Supervised learning trains a model on labeled data sets to recognize patterns, then uses them to label new data.

b. Unsupervised learning

Unsupervised learning groups unlabeled data according to similarities and differences.

c. Reinforcement learning

Reinforcement learning trains an AI system through feedback, in the form of rewards or penalties, after it takes actions.

3. Automation

Tasks can be enhanced when automation tools are coupled together with AI. Big enterprise jobs can be automated while the intelligence from AI is passed on to process changes.

a. Machine Vision

Machine Vision uses a camera, digital signal processing, and analog-to-digital conversion to capture and then analyze visual information. It is used in applications ranging from signature analysis to medical analysis.

b. Self-driving Cars

Self-driving cars use deep learning, image recognition, and machine vision to make sure the vehicle stays in the proper lane as well as dodges pedestrians.

c. Robotics

Robotics is an engineering field that focuses on designing and manufacturing robots. Nowadays, Machine Learning is being used to build robots so that they can interact with society.

What are the applications of Artificial Intelligence?

Now, it is time for us to know various real-life applications of AI.

1. Fraud Detection

Every time you make a transaction online/offline, using your credit or debit card, you receive a message from your bank asking if you have made that transaction. The bank also asks you to report if you haven’t made the transaction.

Banks feed their Artificial Intelligence systems with data regarding both fraudulent and non-fraudulent transactions. These systems learn from this data and then predict which transactions are fraudulent and which are not based on these huge training datasets.

2. Music and Movie Recommendations

Did you know that Mark Zuckerberg created Synapse, a music player that suggested songs that users would likely listen to?

Netflix, Spotify, and Pandora also recommend music and movies to users based on their past interests and purchases. These sites accomplish this by garnering the choices users had made earlier and providing these choices as inputs into the learning algorithm.

Users often look for more than just recommendations; they want a music app that understands their emotions. For instance, if someone feels sad, they might want music that can uplift their spirits. Similarly, if they are angry, they might prefer tunes that help them calm down. These emotional connections are essential, and the learning algorithms used by apps like Spotify and Pandora aim to cater to these specific needs, making the user experience more personalized and meaningful.

3. AI in Retail

The impact of Artificial Intelligence (AI) on the retail industry is remarkable. The AI software market is predicted to soar to an impressive $467 billion by 2030, drawing substantial attention from retailers. This heightened interest has driven both big and small-scale businesses to embrace AI in innovative ways throughout the entire product life cycle.

From the initial stages of product assembly to post-sale customer-service interactions, AI is revolutionizing the retail landscape. Retailers are harnessing AI to enhance customer experiences, streamline inventory management, and optimize marketing strategies.

4. Autopilot Flight

With AI technology, a pilot only needs to put the system on autopilot mode, and then the majority of operations on the flight will be taken care of by AI itself. It is reported by the New York Times that only 7 minutes of human intervention (which mostly relates to takeoff and landing) is required for the average flight of a Boeing plane.

5. AI in Healthcare

With the help of radiological tools like MRI machines, X-rays, and CT scanners, AI can identify diseases such as tumors and ulcers in the early stages. For diseases like cancer, there is no solid treatment, but the risk of premature death can be greatly reduced if the tumor is detected in its early stage. Similarly, AI can suggest medications and tests by analyzing patients’ electronic health records.

AI is also used to study the effects of certain drugs on the human body and to identify alternatives to existing ones.

6. AI in Transportation

Autonomous vehicles are truly breaking the barrier between fiction and reality. With advanced AI algorithms, cameras, LIDAR, and other sensors, collect data about their surroundings, analyze it, and make decisions accordingly.

An autopilot in a commercial plane can take over control after takeoff and keep flight parameters, such as altitude, speed and heading, within set values. Advanced navigation systems also help cargo ships adapt quickly to changing ocean conditions that may be dangerous, saving time.
