Machine Learning - The Subset of AI
You often heard the term Machine Learning. Today, we are trying to answer a few questions that arise in your mind. What is Machine Learning? What discipline of science does it belong to? What connection does Machine Learning (ML) have with Artificial Intelligence (AI)? Are ML and AI the same concepts and can be used interchangeably? What strong capabilities does ML have that make it the most exciting and dominant discipline? What are the types and applications of ML?
Let’s try to understand the underlying concepts by starting from AI.
Artificial Intelligence (AI)
Artificial Intelligence (AI) is the branch of computer science that deals with building machines and robotic systems to perform complex tasks requiring human intelligence. Put it simply, AI is the phenomenon of creating machines that are intelligent.
Human Intelligence is the mental capacity to learn from the past, understand and react to complex or evolving situations, and adapt to new environments or conditions. So, AI is trying to induce human intelligence in machines to mimic human behavior or thinking process.
Based on capabilities, AI is categorized as:
Weak AI
Also known as Narrow AI, capable of performing a single dedicated task. For example, google translate can translate from one language to another, but it cannot reply to your queries as Siri does, and vice versa.
Strong AI
Also known as Artificial General Intelligence (AGI), capable of understanding and performing the tasks as human beings do. The strong AI machine should be as smart as the human mind to concentrate and solve various intelligent tasks. We did not get much success in creating strong AI solutions yet, except for a few tests like Turing Test.
Super AI
Intelligence beyond Human Intelligence, Super AI is the theoretical concept where machines can perform much better than humans.
Machine Learning
Machine Learning (ML) is the branch of AI, where machines learn from the experience without being explicitly programmed. It is the form of AI where the historical or past data is fed into the algorithms as an input, and the predictions of the outcomes or future values are received as an output. We can refer to it as data-driven AI.
ML algorithms have strong capabilities to get insights into the past. Businesses can use ML to know the hidden patterns of customer behavior and operational processes, devise future strategies, and better decision-making after analyzing the previous trends and patterns. ML is successfully being deployed in many application domains including recommendation systems, object recognition, business intelligence, customer relationship management, self-driving cars, smart security systems, precision agriculture, smart farming, medical diagnostics, genome analyses, financial analysis, and so on.
Based on the learning principle, ML models are characterized as:
Supervised Learning
Unsupervised Learning
Semi-supervised learning
Reinforcement Learning
