What is Artificial Intelligence?

Artificial Intelligence (AI) is like giving computers or machines the ability to think and make decisions similar to how humans do, but 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. It’s like making machines smart and capable of doing tasks that usually require human intelligence

For example, when you talk to Siri, Alexa, or Google Assistant, they use AI to grasp your voice commands and offer answers or do tasks. Services like Netflix and YouTube rely on AI to recommend movies or videos you might enjoy, taking into account your previous choices.

History of Artificial Intelligence

As mentioned above, 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.’

Although, 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:

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.

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 the Dartmouth conference, and it was accepted as an academic field.

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 coined as reinforced learning. In 1972, Japan built the first intelligent humanoid robot named ‘WABOT-1.’ Since then, robots are constantly being developed and trained to perform complex tasks in various industries.

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. Al algorithms like backpropagation, which uses neural networks to understand a problem and find the best possible solution, were used.

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.

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.

Deep Learning, Big Data, and Artificial General Intelligence (2011–Present)

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 the 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.

Why is Artificial Intelligence important?

Artificial Intelligence (AI) serves a wide range of purposes and has become increasingly important in various aspects of modern society. Here are some key reasons why we need artificial intelligence:

Automation and Efficiency

Artificial Intelligence (AI) is capable of handling tasks that are monotonous, time-intensive, or pose risks to humans. This results in heightened efficiency and productivity across diverse sectors, including manufacturing, healthcare, finance, banking, and transportation.

Improved Decision-Making

AI systems can process and analyze vast amounts of data quickly and accurately. This enables better decision-making in fields like healthcare diagnosis, financial trading, and logistics planning.

Personalization and Recommendations

AI-driven systems possess the ability to comprehend individual preferences and behaviors, enabling them to offer tailored experiences. This is used in platforms such as Netflix, Spotify, and Amazon, which employ AI to recommend content or products based on a user’s past interactions.

Predictive Analytics and Forecasting

Artificial Intelligence has the capability to check past data in order to make projections and anticipations. This holds significant value in areas like weather forecasting, demand projection, and making predictions in the stock market.

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 nothing but 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.

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

How does Artificial Intelligence work

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. Thus, we have the output for the entire 100 percent of the data that has been acquired from 2006 to 2019.

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 which has been fed into it.

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.

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.

With more and more sets of data being fed into the system, the output becomes more and more precise. Well, we have to note a point that none of the algorithms can be 100 percent correct. None of the machines have been able to attain 100 percent efficiency as well.

Types of Artificial Intelligence

There are four types of AI:

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 can by-pass human intelligence too
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

The following are the advantages of Artificial Intelligence:

  • 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.
  • Risk avoidance: Replacing humans with intelligent robots to do dangerous tasks is one of the biggest advantages of Artificial Intelligence. AI robots are now doing risky things replacing humans in places such as coal mines, exploring the deepest parts of the ocean, sewage treatment, and nuclear power plants to avoid any disaster.
  • 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 it 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.
  • Digital assistance: With digital assistants to interact with users 24/7, organizations can save the need for human resources 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.

There are some disadvantages of AI as well which are listed below:

High cost of creation

It may sound a little spooky, but the rate at which computational devices are upgraded is phenomenal. Machines need to be repaired and maintained with time to keep the latest requirements in check, which needs a lot of resources.

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 more weight, thereby increasing the production cycle. However, machines cannot build an emotional connection with other human beings, which is a crucial aspect of team management.

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.

Can’t think for Itself

Artificial Intelligence aims to process data and make a conscious decisions as we humans do. But, at present, it 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 organism, it will not stop even if it hits a deer and knock it off.

Examples of Artificial Intelligence

The goal of an AI is to make tasks easier for humans. Due to this AI is used in different types of technologies today. For example,

ChatGPT

ChatGPT, a product of OpenAI, exemplifies the power of Artificial Intelligence (AI) in today’s world. It operates through a straightforward two-step process. 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.

Machine Learning

It helps computers act without the need for programming. There are three types of machine learning:

  • Supervised learning – Patterns can be recognized using labeled data sets and then used to label new data sets.
Supervised learning
  • Unsupervised learning – Data sets can be sorted according to how similar or different they are.
Unsupervised learning
  • Reinforcement learning – The AI system is given feedback after actions are performed.
Reinforcement Learning

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.

  • Machine Vision – Machine Vision uses a camera, digital signal processing, and analog-to-analog conversion, to capture and then analyze visual information. It is used in signature analysis to medical analysis.
Machine Vision
  • Self-driving Cars – Automatic vehicles use deep learning, image recognition, and machine vision to make sure the vehicle stays in the proper lane as well as dodges pedestrians.
Self-driving Cars
  • Robotics – Robotics is an engineering field that focuses on the designing and manufacturing of 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.

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.

Fraud Detection

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.

Music and Movie Recommendations

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

Music and Movie Recommendations

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.

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 US$36 million by 2025, 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.

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.

AI in Healthcare

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, It can suggest medication and tests by analyzing their R-Health records.

AI is also used to study the effects of certain drugs on the human body and alternates for pre-existing ones.

AI in Transportation

AI in Transportation

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

An autopilot in a commercial plane can take over the control after takeoff and make sure that all the parameters are matched. Moreover, advanced navigation systems are used for swift adaptations to save precious time and adapt to the changing conditions in the ocean, which might be dangerous for cargo ships.

Conclusion

There is a growing fear that the widespread implementation of AI will erode human jobs. Not just commoners but entrepreneurs like Elon Musk are voicing alerts at the growing pace of research undertaken in the AI domain. They are also in a view that AI systems may pave a way for large-scale violence in the world. But that is a very narrow way of looking at things!

In recent decades, technology has grown rapidly and massively. During the entire course, for every job lost to technology, there were always fresh and new job roles emerging. If it had been the case where a new technology replaced all human jobs, then, by now, the majority of the world would have gone jobless. Even the Internet during its inception had garnered many negative reviews. But, it is now obvious that the Internet can never be replaced. You wouldn’t be reading this blog if that was the case. Similarly, though it automates much of the human capabilities, it will rise in its potential and goodwill and benefit mankind in general.
