Decoding Artificial Intelligence: What You Should Know

What is Artificial Intelligence (AI)?

AI is a field of computer science dedicated to creating machines that can perform tasks that typically require human intelligence. This includes learning from experiences, understanding languages, recognizing patterns, solving problems, and making decisions. Let’s discuss a simple, everyday example to give you an idea of what exactly AI is. Consider a smartphone voice assistant, like Siri or Google Assistant. These assistants use AI to understand your voice commands and respond appropriately.

Machine learning algorithms enable AI systems to learn from data, improving their performance on tasks over time without explicit reprogramming .

How Does AI Work?

AI works by processing large amounts of data and learning from it. This is often done through a process called machine learning, where algorithms improve their performance as they are exposed to more data. Let’s consider Netflix's recommendation system as an example. It suggests movies and TV shows based on what you have watched before. The system learns from your viewing habits and the habits of other users. In terms of the applications of AI, it is used in various fields like the ones stated below that help in bringing improvements and innovations:

• Healthcare
• Finance
• Transportation
• Entertainment

Brief History and Evolution of AI

The journey of AI began in the first half of the 20th century with science fiction introducing the concept of artificially intelligent robots. By the 1950s, the groundwork for AI was set by individuals like Alan Turing, who proposed that machines could use information and reasoning to solve problems and make decisions.

The real progress in AI began after 1949 when computers evolved to store commands, not just execute them. In the 1950s, the first AI program, the Logic Theorist, was developed by Allen Newell, Cliff Shaw, and Herbert Simon, marking the inception of AI as a field. Between 1957 and 1974, AI flourished with advancements in machine learning and increased computer storage and processing capabilities. Early successes included programs like the General Problem Solver and ELIZA, stimulating significant interest and investment in AI research.

The field faced challenges in the 1970s and 1980s due to computer-related limitations. However, it regained momentum in the 1980s with the development of deep learning techniques and expert systems. The 1990s and 2000s saw landmark achievements in AI, such as IBM’s Deep Blue defeating world chess champion Gary Kasparov and the development of sophisticated speech recognition software. The growth of AI in recent years has been facilitated by the exponential increase in computer storage and processing power.

Types of AI

Narrow AI (Weak AI)

This is the only type of AI that we have successfully realized so far. Narrow AI is designed to perform specific tasks such as facial recognition, speech recognition, driving a car, or internet searches. It operates under a limited set of constraints and doesn't replicate human intelligence but simulates human behavior in specific contexts. Examples of narrow or weak AI include IBM Watson, AlphaGo, and Google Assistant.

General AI (Strong AI)

This type of AI remains theoretical and refers to a machine's ability to copy human intelligence, understanding, and behavior across a wide range of tasks. General or strong AI would be capable of applying its intelligence to solve any problem, much like a human, and involves understanding emotions, needs, and beliefs. Achieving Artificial General Intelligence (AGI) is a significant challenge due to the complexity of human cognitive processes .

Superintelligent AI

This hypothetical form of AI surpasses human intelligence and capability. It remains a subject of speculation and debate, with theories ranging from dystopian scenarios where superintelligent AI poses risks to humanity, to optimistic views of AI enhancing human life. Super AI has human-like capabilities like:

• Consciousness
• Beliefs
• Desires
• Cognition
• Emotional intelligence
• Subjective experiences
• Behavioral intelligence
