Artificial Intelligence (AI) has become a discussed subject, in today’s fast-moving world. It has transitioned from being a concept in science fiction to a reality that impacts our daily lives. People all over the world are fascinated by AI and its ability to bring their imaginations to work in their daily lives.
In this article, we will know about What is Artificial Intelligence?, its evolution, various types of AI, training models, benefits.
What is Artificial Intelligence?
Artificial Intelligence (AI) refers to the development of computer systems of performing tasks that require human intelligence. AI aids, in processing amounts of data identifying patterns and making decisions based on the collected information. This can be achieved through techniques like Machine Learning, Natural Language Processing, Computer Vision and Robotics. AI encompasses a range of abilities including learning, reasoning, perception, problem solving, data analysis and language comprehension. The ultimate goal of AI is to create machines that can emulate capabilities and carry out diverse tasks, with enhanced efficiency and precision. The field of AI holds potential to revolutionize aspects of our daily lives.
Examples of Artificial Intelligence
Artificial Intelligence (AI) has become increasingly integrated into various aspects of our lives, revolutionizing industries and impacting daily routines. Here are some examples illustrating the diverse applications of AI:

AI has the potential to revolutionize many industries and fields, such as healthcare, finance, transportation, and education. However, it also raises important ethical and societal questions, such as the impact on employment and privacy, and the responsible development and use of AI technology.
Importance of Artificial Intelligence
Today, the amount of data in the world is so humongous that humans fall short of absorbing, interpreting, and making decisions of the entire data. This complex decision-making requires higher cognitive skills than human beings. This is why we’re trying to build machines better than us, in these task. Another major characteristic that AI machines possess but we don’t is repetitive learning. Let consider an example of how Artificial Intelligence is important to us. Data that is fed into the machines could be real-life incidents. How people interact, behave and react ? etc. So, in other words, machines learn to think like humans, by observing and learning from humans. That’s precisely what is called Machine Learning which is a subfield of AI. Humans are observed to find repetitive tasks highly boring. Accuracy is another factor in which we humans lack. Machines have extremely high accuracy in the tasks that they perform. Machines can also take risks instead of human beings. AI is used in various fields like:
Health Care
Retail
Manufacturing
Banking etc.
What are the types of Artificial intelligence?
AI can be broadly classified into two major categories:
Based on Capabilities:
1. Narrow AI: Narrow AI, also known as Weak AI, refers to artificial intelligence systems that are designed and trained to perform a specific task or a narrow range of tasks. These systems excel at their designated tasks but lack the broad cognitive abilities and understanding of human intelligence. Narrow AI is the most common form of AI currently in use and has found widespread application across various industries and domains.
Characteristics of Narrow AI include:
Specialized capabilities: Narrow AI systems are highly specialized and focused on performing a specific function or solving a particular problem.
Limited scope: These systems are not capable of generalizing their knowledge or skills to other domains outside of their designated tasks.
Lack of consciousness: Narrow AI lacks self-awareness and consciousness. It operates based on predefined algorithms and data inputs without understanding the context or implications of its actions.
Examples: Virtual personal assistants like Siri and Alexa, recommendation systems, image recognition software, chatbots, and autonomous vehicles are all examples of Narrow AI.
2. General AI: Also referred to as “General AI”. Here is where there is no difference between a machine and a human being. This is the kind of AI we see in the movies, the robots. A close example (not the perfect example) would be the world’s first citizen robot, Sophia. She was introduced to the world on October 11, 2017. Sophia talks like she has emotions.
General AI, also known as Strong AI or Artificial General Intelligence (AGI), refers to artificial intelligence systems that replicate human-like cognitive abilities and understanding across a wide range of tasks and domains. Unlike Narrow AI, which is task-specific, General AI aims to simulate human intelligence comprehensively, including reasoning, problem-solving, learning, and adaptation to new situations.
Characteristics of General AI include:
1.Human-like cognitive abilities: General AI systems can understand, learn, and apply knowledge across various tasks and domains, similar to human intelligence.
Adaptability: These systems have the ability to generalize their knowledge and skills to new situations, tasks, and environments.
2.Consciousness: General AI is theorized to possess self-awareness, consciousness, and subjective experiences, although achieving this level of intelligence remains a theoretical challenge.
Examples: General AI remains largely theoretical and speculative, as researchers have not yet achieved human-level artificial intelligence. Development in this area continues to be a subject of ongoing research and exploration.
3. Super Intelligent AI: Super intelligent AI refers to artificial intelligence systems that surpass human intelligence in virtually every aspect. This type of AI, also known as Artificial Superintelligence (ASI), represents the highest level of AI capabilities and poses significant implications for society and the future of humanity.
Characteristics of Super intelligent AI include:
Cognitive superiority: Super intelligent AI outperforms humans in terms of cognitive abilities, including problem-solving, creativity, and strategic planning.
Rapid learning and adaptation: These systems can acquire and process information at an unprecedented speed and scale, leading to rapid advancements in various fields.
Ethical and existential risks: The development of Super intelligent AI raises concerns about its potential impact on society, including risks related to control, alignment with human values, and existential threats to humanity.
Examples: Super intelligent AI remains theoretical, and no concrete examples exist as of now. However, researchers are actively exploring the implications and challenges associated with its development.
Based on Functionalities :
1. Reactive machines: These are the most basic type of AI and are purely reactive as the name suggests. They neither can form memories nor can use past experiences to form decisions. An example would be IBM’s Deep Blue chess-playing supercomputer which is mentioned above. Deep Blue beat the international grandmaster Garry Kasparov in 1997. It can choose the most optimal of the chess moves and beat the opponent. Apart from a rarely used chess-specific rule against repeating the same move three times, Deep Blue ignores everything before the present moment, thus not storing any memories. This type of AI just perceives the world, the chess game in the case of Deep Blue, and acts on it.
2. Limited memory: These machines can look into the past. Not the ability to predict what happened in the past, but the usage of memories to form decisions. A common example could include self-driving cars. For example, they observe other cars’ speed and directions and act accordingly. This requires monitoring of how a car is driven for a specific amount of time. Just like how humans observe and learn the specifics. These pieces of information are not stored in the library of experiences of the machines, unlike humans. We humans automatically save everything in the library of our experiences and can learn from it, but limited memory machines can’t.
3. Theory of mind: These are types of machines that can understand that people have beliefs, emotions, expectations, etc., and have some of their own. A “theory of mind” machine can think emotionally and can respond with emotions. Even though there are close examples of this kind of AI like Sophia, the research is not complete yet. In other words, these machines have a notion of not just the world, but also the existing entities of the world, like human beings, animals, etc. These machines will be capable of answering simple “what if” questions. They’ll have a sense of empathy.
4. Self-Awareness: These types of machines can be called human equivalents. Of course, no such machines exist and the invention of them would be a milestone in the field of AI. These basically will have a sense of consciousness of who they are. The sense of “I” or “me”. Here’s a basic example of the difference between “theory of mind” and “self-awareness” AI. The feeling of I want to play is different from the feeling of I know I want to play. In the latter, if you notice, there is a sense of consciousness and is a characteristic of a self-aware machine, while the former feeling is a characteristic of a theory-of-mind machine. Self-aware machines will have the ability to predict others’ feelings. Let’s hope the invention is not so far away.
How Does AI Work ?
Artificial Intelligence (AI) uses a wide range of techniques and approaches that enable machines to simulate human-like intelligence and perform tasks that traditionally require human assistance. AI systems work through a combination of algorithms, data, and computational power. Here’s an overview of how AI works:
Data Collection: AI systems rely on vast amounts of data to learn and make decisions. Data can be collected from various sources, including sensors, digital devices, databases, the internet, and user interactions. The quality and quantity of data are crucial for training accurate and reliable AI models.
Data Pre-processing: Once data is collected, it needs to be pre-processed to ensure it’s clean, structured, and suitable for analysis. This pre-processing stage may involve tasks such as cleaning noisy data, handling missing values, standardizing formats, and encoding categorical variables.
Algorithm Selection: AI algorithms are chosen based on the specific task or problem the AI system aims to solve. Different algorithms are suited for different types of tasks, such as classification, regression, clustering, and pattern recognition. Common AI algorithms include neural networks, decision trees, support vector machines, and k-nearest neighbours.
Model Training: In the training phase, AI models are fed with labelled data (supervised learning) or unlabelled data (unsupervised learning) to learn patterns and relationships. During training, the model adjusts its parameters iteratively to minimize errors and improve its performance on the given task. This process involves optimization techniques like gradient descent and backpropagation in neural networks.
Model Evaluation: After training, the AI model is evaluated using separate validation data to assess its performance and generalization ability. Performance metrics such as accuracy, precision, recall, F1-score, and area under the curve (AUC) are used to quantify the model’s effectiveness in making predictions or decisions.
Model Deployment: Once the AI model meets the desired performance criteria, it can be deployed into production environments to perform real-world tasks. Deployment involves integrating the model into existing systems, such as mobile apps, web services, or embedded devices, to provide AI-driven functionalities.
Continuous Learning and Improvement: AI systems can adapt and improve over time through continuous learning. They can be updated with new data and retrained periodically to stay relevant and accurate in dynamic environments. Techniques like online learning, transfer learning, and reinforcement learning enable AI models to learn from new experiences and feedback.
Inference and Decision-Making: During inference, the trained AI model applies its learned knowledge to make predictions or decisions on new, unseen data. Inference involves feeding input data into the model and obtaining output predictions or classifications based on the model’s learned patterns and representations.
Overall, AI systems work by leveraging data, algorithms, and computational power to learn from experience, make decisions, and perform tasks autonomously. The specific workings of an AI system depend on its architecture, algorithms, and the nature of the tasks it’s designed to accomplish.
