This guide aims to provide clarity on AI vs. machine learning by unraveling the distinctions between them and fostering a comprehensive understanding.
Let’s take a closer look at each of these technologies.
What is Artificial Intelligence?
Artificial intelligence, often abbreviated as AI, is the process of imparting data, information, and human intelligence to machines. Its main goal is to develop self-reliant machines that can think and act like humans. AI machines can mimic human behavior and perform tasks by learning and problem-solving. Most AI systems simulate natural intelligence to solve complex problems.
Types of Artificial Intelligence:
- Reactive machines are systems that only respond. These systems do not create memories and do not make judgments based on previous experiences.
- Limited Memory: These systems refer to the past and add information over time. The information referred to is transient.
- The theory of mind refers to systems that can comprehend human emotions and how they influence decision-making. They are taught to modify their behavior accordingly.
- Self-awareness: These systems are intended and built to be self-aware. They comprehend their internal states, anticipate the emotions of others, and behave appropriately.
Artificial Intelligence Applications
Examples of artificial intelligence applications include:
- Machine translation, exemplified by tools like Google Translate.
- Autonomous vehicles, as demonstrated by Google’s Waymo.
- AI-driven robots, such as Sophia and Aibo.

Having covered the fundamentals of artificial intelligence, let’s now delve into the workings of machine learning.
What is machine learning? And how does it work?
Machine Learning is a field within computer science that employs algorithms and analytics to construct predictive models capable of addressing various business challenges. According to McKinsey & Co., machine learning relies on algorithms that can derive insights from data without being explicitly programmed with rules.
The process involves the utilization of extensive datasets, encompassing both structured and unstructured information, from which the machine learns to make predictions about future outcomes. This learning is facilitated through the application of diverse algorithms and techniques. The following diagram illustrates the mechanism through which a machine assimilates knowledge from data.
Now that you have a foundational understanding of machine learning and its functioning, let’s explore the various types of machine learning methods.
Types of Machine Learning:
Machine learning algorithms are broadly categorized into three main types based on the learning style and nature of the task they are designed to perform. These three categories are:
- Supervised Learning:
Description: In supervised learning, the algorithm is trained on a labeled dataset, which means the input data is paired with corresponding output labels. The model learns the mapping function from the input to the output by generalizing patterns from the labeled examples.
Use Cases: Common applications include classification and regression tasks. For example, predicting whether an email is spam (classification) or predicting house prices based on features like square footage, number of bedrooms, etc. (regression).
- Unsupervised Learning:
Description: Unsupervised learning deals with unlabeled data, and the algorithm is tasked with finding patterns or structures within the data without explicit guidance in the form of labeled output. The goal is often to discover inherent relationships, groupings, or representations within the data.
Use Cases: Clustering and dimensionality reduction are common tasks in unsupervised learning. For instance, grouping similar customer profiles based on their purchasing behavior (clustering) or reducing the number of features while retaining the essential information in the data (dimensionality reduction).
- Reinforcement Learning:
Description: Reinforcement learning involves training an agent to make decisions in an environment by receiving feedback in the form of rewards or penalties. The agent learns to take actions that maximize the cumulative reward over time. It involves an exploration-exploitation trade-off, where the agent learns by interacting with the environment.
Use Cases: Applications include game playing (e.g., AlphaGo), robotic control, and autonomous systems. The agent learns to navigate its environment and make decisions that lead to favorable outcomes based on trial and error.
These three types form the foundation of machine learning, and many algorithms can be classified into one of these categories or a combination of them. Additionally, there are subfields and specialized techniques within each category, such as semi-supervised learning, self-supervised learning, and ensemble methods, which further expand the range of tools available in machine learning.
Applications of Machine Learning
Machine learning finds diverse applications in various domains, including:
- Sales Forecasting for Different Products

Following our discussion of machine learning and its applications, let’s discuss the differences between AI and machine learning.
AI vs Machine Learning: What Is the Difference?
The main difference between Artificial Intelligence (AI) and Machine Learning (ML) lies in their scope and functionality. While AI encompasses the broader concept of machines mimicking human intelligence, ML is a subset of AI with a more specific focus.
In essence, AI aims to create machines that can replicate human-like intelligence across various tasks, including problem-solving, reasoning, and perception. On the other hand, ML is a technique within the AI realm that concentrates on instructing machines how to execute particular tasks and deliver accurate outcomes by recognizing and adapting to patterns in data.
The scenario here is about asking a device for information about your daily commute. The machine’s task is to provide you with an estimate of your commute time. Machine learning (ML) plays an important role in training algorithms to analyze live transit and traffic data and predict traffic volume and density. However, the focus is primarily on identifying patterns, assessing the accuracy of predictions, and learning from data to improve performance for that specific task. In this context, the goal of ML is not to enable the machine to perform a wide range of tasks autonomously but to refine its proficiency in a targeted area.
