What Makes AI So Powerful?
Artificial Intelligence is the simulation of human intelligence processes by machines, especially computer systems. These processes include learning, reasoning, and self-correction. It all started with knowledge reasoning across six key areas: planning, machine learning, natural language processing, computer vision, robotics, and artificial general intelligence. Following the reasoning process, humans were able to create something artificial that can understand needs, analyse massive amounts of data, and make intelligent decisions. With AI, businesses have changed dramatically, humongous data is being analysed to map poverty and climate change, and automation in agricultural practices and irrigation is happening at a fast pace.
1. Artificial Intelligence in Healthcare
Health is wealth, and the rate at which humans are compromising on it is concerning. With AI, natural language processing helps respond to questions that are asked. AI enables workflow assistants which help doctors free up their schedules and reduce the time and cost by streamlining processes. AI-powered technology helps pathologists in analysing samples of tissue and helps diagnosis to be more accurate.
Decision Support and Research
AI supports clinical decision making and research by analysing patient data, medical literature, and treatment outcomes to recommend the best course of action for individual patients.
Integrated Medical Sciences
AI helps integrate activities across medical, software, and cognitive sciences, creating a content-rich discipline for future scientific medical communities and accelerating drug discovery.
2. Artificial Intelligence in Business
A business heavily relies on real-time reporting, accuracy, and processing of large volumes of quantitative data to make crucial decisions. With AI, the efficiency and effectiveness of a business improves quickly through machine learning. Adaptive intelligence, chatbots, and automation help smoothen out the business process. For example, when you visit a website and a chat window pops up allowing you to ask questions directly, that is AI at work through robotic process automation. This reduces the repetitive tasks that are normally performed by humans. AI algorithms are integrated into analytics and CRM platforms to uncover information on how to better serve customers.
3. Artificial Intelligence in Education
With AI, checking homework and grading tests for large lecture courses can be automated. Although it can never replace human work, AI-powered automated grading systems can check multiple-choice questions, fill-in-the-blank testing, and even written assignments in a fraction of the time. More importantly, AI can identify gaps in learning that teachers might miss. When a student is confused about certain concepts, the system alerts the teacher and offers hints to guide the student toward the correct answer. This helps fill gaps in explanation that might occur in courses and ensures students build the same conceptual foundation.
4. Artificial Intelligence in Autonomous Vehicles
Long-range radar, cameras, and LIDAR are used in autonomous vehicles, with each technology collecting different pieces of information. AI acts as the brain that processes this information and derives insights. Self-driving cars use AI for directing the car to a gas station or recharge station when running low on fuel, adjusting trip directions based on known traffic conditions to find the quickest route, incorporating speech recognition for advanced communication with passengers, and using natural language interfaces and virtual assistance technologies.
5. Artificial Intelligence in Social Media
Instagram, Snapchat, Facebook, and Twitter use AI to influence a majority of your decisions. Starting from notifications to content recommendations, everything is curated by AI. It considers all your past web searches, behaviours, and interactions. While you visit these websites, your data is being stored and analysed to serve you a personalised experience. The AI learns what content keeps you engaged and adjusts your feed accordingly.
6. Artificial Intelligence for a Better World
Technology is making the world a better place to live. AI helps prevent future damage by understanding needs and addressing developmental needs while focusing on sustainability. Companies like Microsoft use AI to study land-use patterns with terrain maps. By understanding these patterns in-depth, better decisions related to land are taken. This helps implement proper preservation techniques. Scientists use the information obtained to preserve biodiversity and the ecosystem.
7. Artificial Intelligence in Tourism
Competition in the travel and tourism industry is very high. Prices keep fluctuating and changing often. With predictive analytics driven by AI, price patterns can be predicted based on recorded data on each route. The application is able to analyse price trends and alert travellers when to buy tickets at the cheapest rate. You get notifications of when to book your flight, allowing you to book it at the right time and at the right price.
Types of Artificial Intelligence
To fully understand AI applications, it helps to know the different categories of artificial intelligence. AI is classified in two main ways: by capability (Weak vs Strong) and by functionality (four distinct types).
Weak AI vs Strong AI
| Type | Description | Example |
|---|---|---|
| Weak AI (Narrow AI) | Designed and trained for a specific type of task. Has programmed responses and classifies things accordingly. | Siri and Alexa |
| Strong AI (AGI) | Has cognitive abilities to perform unfamiliar tasks. Can find solutions beyond a preprogrammed algorithm. | Visual perception, speech recognition, decision making |
Four Types Based on Functionality
Reactive Machines
These use past experiences to determine future actions but do not refer to past experiences to improve. They simply perceive the world and react to it with no memory.
Limited Memory
Retains data for a short period and uses it for specific tasks. Cannot add it to a library of experiences. Used in autonomous vehicles for storing recent speed of nearby cars, distance, and speed limits.
Theory of Mind
This type imitates the mental models of the human brain. It forms representations about the world starting from thoughts, emotions, and memories. This is the future of AI and does not exist as of now.
Self-Awareness
Machines that understand their own current state and can use that information to infer what others are feeling. This type of AI does not yet exist but will be there in the near future.
Understanding AI Types Matters
When you hear about AI in the news, knowing whether it is Weak AI (narrow, task-specific applications like Siri) or Strong AI (general intelligence that can handle unfamiliar tasks) helps you evaluate claims realistically. Most AI in use today is Weak AI or Limited Memory AI.
Frequently Asked Questions
What is the difference between Weak AI and Strong AI?
Weak AI (Narrow AI) is designed for a specific task like voice assistants Siri and Alexa. Strong AI (AGI) has general cognitive abilities to perform unfamiliar tasks beyond its programming, like visual perception and decision making across different domains.
How is AI used in healthcare today?
AI supports clinical decision making and research, helps pathologists analyse tissue samples for more accurate diagnosis, enables workflow assistants that free up doctors schedules, and integrates medical software with cognitive sciences.
What type of AI do self-driving cars use?
Self-driving cars primarily use Limited Memory AI. They store data such as the recent speed of nearby cars, distance, speed limits, and other information that helps them navigate roads. They cannot add this data to a permanent library of experiences.
How does AI personalise social media feeds?
AI analyses your past web searches, behaviours, interactions, and engagement patterns on platforms like Instagram and Facebook. It then curates notifications, content recommendations, and advertisements to serve you a personalised experience.
Does Self-Aware AI exist yet?
No, Self-Aware AI and Theory of Mind AI do not exist yet. These are future concepts where machines would understand their own state and infer what others are feeling. All AI in use today falls under Reactive Machines or Limited Memory categories.
