Machine Learning vs Artificial Intelligence: Key Differences and Industry Applications
We may have heard of people using these two terminologies quite interchangeably - Artificial Intelligence and Machine Learning - more so when one is discussing big data, predictive analytics, and other discourses about digital transformation. There is a reason people get confused. After all, artificial intelligence and machine learning are related concepts. These trending technologies differ in several aspects, such as scope and applications.
Increasingly AI and ML products have proliferated as businesses use them to process and analyze immense volumes of data, drive better decision-making, generate recommendations and insights in real-time, and create accurate forecasts and predictions.
So, what exactly is the difference when it comes to ML vs. AI, how are ML and AI connected, and what do these terms mean in practice for organizations today?
We’ll break down AI vs. ML and explore how these two innovative concepts are related and what makes them different from each other.
What is Artificial Intelligence?
Artificial intelligence is a generic term associated with technologies for developing machines and computers capable of emulating one or more cognitive functions that humans associate with their intelligence. These may be seeing, understanding, or responding to spoken or written languages, analyzing data, making recommendations, and so on.
Learning AI is essential for anyone looking to innovate and advance in the tech industry, as it equips individuals with the ability to create intelligent systems that can perform complex tasks and provide valuable insights.
Types of AI
Artificial intelligence (AI) may be categorized on two grounds: based on capacity and based on functionality. Herewith is the analysis of each with definitions and examples:
Capability-Based Types of AI
This approach focuses on the level of intelligence an AI system possesses. There are three main categories:
1. Narrow AI (ANI):
Also known as Narrow Artificial Intelligence, it is the general form of artificial intelligence that we come across every day in our lives. It has an excellent streak of performing specific tasks at high accuracy but lacks general intelligence.
Some examples of narrow AI include image recognition software, self-driving cars, and AI virtual assistants.
2. General AI (AGI):
It would be such a hypothetical kind of AI that created an intellectual power exactly at the human level: to learn and perform any task with a similar or even superior ability to that of a human. Building from technologies like supercomputers, quantum hardware, and generative AI models such as ChatGPT, the groundwork of artificial general intelligence could be laid.
Examples: Chatbots, virtual assistants, and self-driving cars.
3. Superintelligent AI (ASI):
This even more speculative concept refers to AI surpassing human intelligence in all aspects. It's a popular theme in science fiction, but purely theoretical at this point.
ASI would act as the backbone technology of completely self-aware AI and other individualistic robots. Its concept is also what fuels the popular media trope of “AI takeovers.” But at this point, it’s all speculation.
Functionality-Based Types of AI
4. Reactive Machines:
These AI systems react to their environment based on pre-programmed rules and respond to specific stimuli. They have no memory of past interactions.
Examples: IBM Deep Blue, Netflix Recommendation Engine.
5. Limited Memory Machines:
These AI systems can store and access past data to inform their current decisions. They can react more intelligently than reactive machines but still lack true learning capabilities.
Examples: Chatbots, Virtual Assistants, and Self-Driving Cars.
6. Theory of Mind AI:
This type of still vastly theoretical AI would be able to understand and predict others' thoughts, intentions, and feelings.
Example: Now, imagine that such an assistant is not only ready to assist you by answering your queries but also knows your emotional state and makes responses with empathy or makes appropriate changes in communication accordingly.
7. Self-Aware AI:
This concept is already quite speculative—AI systems that are self-aware would need to understand their own existence, including any associated feelings and consciousness.
Example: Maybe one of the most famous is Sophia, a robot developed by the robotics company Hanson Robotics. Not actually per se self-aware, Sophia's sophisticated application of current AI technologies provides a view of AI's potentially self-aware future.
What is Machine Learning?
Machine learning is a subset of artificial intelligence that automatically enables a machine or system to learn and improve from experience. Instead of explicit programming, machine learning uses algorithms to analyze large amounts of data, learn from the insights, and then make informed decisions.
Learning machine learning is a must for developers and data scientists aiming to stay ahead in the rapidly evolving tech landscape, as it equips them with the skills needed to build intelligent systems and extract meaningful insights from data.
Types of Machine Learning
Machine learning algorithms can be trained in many ways, with each method having its pros and cons. Based on these methods and ways of learning, machine learning is broadly categorized into four main types:
1. Supervised machine learning
This type of ML involves supervision, where machines are trained on labeled datasets and enabled to predict outputs based on the provided training. The labeled dataset specifies that some input and output parameters are already mapped. Hence, the machine is trained with the input and corresponding output. A device is made to predict the outcome using the test dataset in subsequent phases.
For example, consider an input dataset of parrot and crow images. Initially, the machine is trained to understand the pictures, including the parrot and crow’s color, eyes, shape, and size. Post-training, an input picture of a parrot is provided, and the machine is expected to identify the object and predict the output. The trained machine checks for the various features of the object, such as color, eyes, shape, etc., in the input picture, to make a final prediction. This is the process of object identification in supervised machine learning.
2. Unsupervised machine learning
Unsupervised learning refers to a learning technique that’s devoid of supervision. Here, the machine is trained using an unlabeled dataset and is enabled to predict the output without any supervision. An unsupervised learning algorithm aims to group the unsorted dataset based on the input’s similarities, differences, and patterns.
For example, consider an input dataset of images of a fruit-filled container. Here, the images are not known to the machine learning model. When we input the dataset into the ML model, the task of the model is to identify the pattern of objects, such as color, shape, or differences seen in the input images, and categorize them. Upon categorization, the machine then predicts the output as it gets tested with a test dataset.
3. Semi-supervised learning
Learning with the blend of both supervised and unsupervised machine learning, in which the learning is done with both labeled and unlabeled datasets to train its algorithms. Using both types of datasets, semi-supervised learning overcomes the drawbacks of the options mentioned above.
Consider an example of a college student. A student learning a concept under a teacher’s supervision in college is termed supervised learning. In unsupervised learning, a student self-learns the same concept at home without a teacher’s guidance. Meanwhile, a student revising the concept after learning under the direction of a teacher in college is a semi-supervised form of learning.
4. Reinforcement learning
Reinforcement learning is a feedback-based process. Here, the AI component automatically takes stock of its surroundings by the hit & trial method, takes action, learns from experiences, and improves performance. The component is rewarded for each good action and penalized for every wrong move. Thus, the reinforcement learning component aims to maximize the rewards by performing good actions.
Unlike supervised learning, reinforcement learning lacks labeled data, and the agents learn via experiences only. Consider video games. Here, the game specifies the environment, and each move of the reinforcement agent defines its state. The agent is entitled to receive feedback via punishment and rewards, thereby affecting the overall game score. The ultimate goal of the agent is to achieve a high score.
