Artificial Intelligence, machine learning, and deep learning have taken the modern world by storm.
Businesses across the globe are using these concepts to build smart, valuable machines that can ease lives.
Artificial Intelligence (AI) is a “smart” way to create intelligent machines, machine learning (ML) is a part of AI that helps in building AI-driven applications, and Deep Learning (DL) again is a part of machine learning that trains a model with complex algorithms and vast data volumes.
They play a vital role in the industries focusing on providing unique experiences to the users.
Since they are related, most people confuse Artificial Intelligence, machine learning, and deep learning. But these terms are not the same.
In this article, you will understand the similarities and differences between these technologies.
So let’s start digging.
AI vs Machine Learning vs Deep Learning: What Are They?
AI, ML, and Deep Learning are somewhat the same but not in their scope, working procedure, and their interchangeability functionality.
Let’s discuss them one by one to understand what they are and their day-to-day applications in present lives.
What is Artificial Intelligence (AI)?
You cannot define Intelligence as a skill set. It is a process of learning new things on your own with smartness and speed. A human uses intelligence to learn from education, training, work experiences, and more.
Transferring human intelligence to a machine is what we call Artificial Intelligence (AI). Many IT industries use AI to develop self-developing machines that act like humans. AI machines learn from human behavior and perform tasks accordingly to solve complex algorithms.
In simple terms, it is developed in a computer system to control other computer systems. In the 1940s, the first digital computers came into existence, and in the 1950s, the possibility of AI came into existence.
Nowadays, artificial intelligence is used in weather prediction, image processing, search engine optimization, medicine, robotics, logistics, online search, and more. Based on the current functionality, artificial intelligence is classified into four types:
- Reactive Machines AI
- Limited Memory AI
- Theory of Mind AI
- Self-Aware AI
Example: When you talk with Siri or Alexa, you get frequent answers and responses. This is only due to AI inside the machine. It listens to your words, interprets them, understands them, and responds immediately.
Other applications are self-driving vehicles, AI robots, machine translations, speech recognition, and more.
What is Machine Learning (ML)?
Before digging for Machine Learning, you must understand the concept of data mining. Data mining derives actionable information by using mathematical analysis techniques to discover trends and patterns inside the data.
Organizations can use lots of data to improve machine learning techniques. ML provides a way to find a new path or algorithm from data-based experience. It is the study of the technique that extracts data automatically to make business decisions more carefully.
It helps in designing and developing a machine that can grasp specific data from the database to give valuable results without using any code. Thus, ML gives a better way to make predictions from the insights.
So, ML learns from the data and algorithms to understand how to perform a task. It is the subset of AI.
Example: In your day-to-day life, when you open any platform which you frequently use, like Instagram, you can see product recommendations. Websites track your behavior based on the previous search or purchase, ML gets the data and shows you products based on the same pattern.
Many industries use ML to detect, remediate, and diagnose anomalous application behavior in real-time. It has multiple applications in various industries starting from small face recognition applications to big search engine refining industries.
What is Deep Learning
If we are comparing artificial intelligence with human intelligence, then Deep Learning is the neurons inside a human brain. It is rather more complex than machine learning as it uses deep neural networks.
Here, the machines use the technique of several layers to learn. The network consists of an input layer to accept inputs from data and a hidden layer to find the hidden features. At last, the output layer provides the final information.
In other words, Deep Learning uses a simple technique called sequence learning. Many industries use the Deep Learning technique to build new ideas and products. Deep Learning differs from Machine Learning in terms of impact and scope.
AI is the present and future of our growing world. Deep Learning enables practical applications by extending the overall use of AI. Due to Deep Learning, many complex tasks seem possible, such as driverless cars, better movie recommendations, healthcare, and more.
Example: When you think of a driverless car, you must be wondering about how it drives on the road without human assistance. Deep Learning provides human-like expertise in understanding the road structure, pedestrians, speed limits in various scenarios, and more.
With the large data and efficient calculation, a car drives on its own, which means it has a better decision-making flow.
AI vs Machine Learning vs Deep Learning: How They Work?
Now, you know what AI, ML, and Deep Learning are individually. Let’s compare them based on how they work.
How Does AI Work?
Think of artificial intelligence as a way to solve problems, answer questions, suggest something, or predict something.
Systems using AI concepts work by consolidating large data sets with iterative and intelligent algorithms and analyzing the data to learn features and patterns. It keeps on testing and determining its own performance by processing data and makes it smarter to develop more expertise.
AI systems can run thousands and millions of tasks at incredible speeds without requiring a break. Therefore, they learn quickly to be capable of accomplishing a task efficiently. AI aims at creating computer systems mimicking human behavior to think like humans and solve complex questions.
To do this, AI systems leverage various processes, techniques, and technologies. Here are different components of AI systems:
- Neural networks: It’s like a large network of neurons found in human’s brains. It allows AI systems to use large sets of data, analyze them to find patterns, and solve problems.
- Cognitive computing: It imitates the way the human brain thinks while performing tasks to facilitate communication between machines and humans.
- Machine learning: It is a subset of AI that allows computer systems, applications, and programs to automatically learn and develop experience-based results. It enables AI to detect patterns and reveal insights from the data to enhance results.
- Deep learning: It is a subset of machine learning that enables AI to process data and learn and improve by using AI neural networks.
- Computer vision: AI systems can analyze and interpret image content through deep learning and pattern recognition. Computer vision allows AI systems to identify visual data’s components.
For example, captchas learn by asking you to identify bicycles, cars, traffic lights, etc.
- Natural Processing Language (NLP): It allows systems to recognize, analyze, interpret, and learn human language in spoken and written form. It is used in systems that communicate with humans.
So, in order for an AI system to work, it must have all these capabilities. Along with these, AI systems requires some technologies:
- Larger, accessible data sets since AI thrives on it
- Intelligent data processing through advanced algorithms to analyze data at speeds simultaneously and understand complex problems and predict events.
- Application Programming Interfaces (APIs) to add AI functions to a system or application and make them smarter.
- Graphical Processing Units (GPUs) to provide power to AI systems to perform heavy computations to data processing and interpretation.
How Does Machine Learning Work?
Machine learning uses a large amount of data by using various techniques and algorithms to analyze, learn, and predict the future. It involves lots of complex coding and maths that serve some mathematical function.
It explores data and identifies patterns in order to learn and improve based on its previous experiences. It teaches AI systems to think as humans do. Machine learning helps automate tasks that are completed with a set of rules and data-defined patterns. This way, businesses can use AI systems to perform tasks at speeds. ML uses two primary techniques:
- Unsupervised learning: It helps find known patterns in gathered data
- Supervised learning: It enables data collection or produces output from past ML deployments.
How Does Deep Learning Work?
It starts by designing a deep learning model to continually observe and analyze data involving a logical structure like the way humans draw conclusions.
For this analysis to complete, deep learning systems utilize a layered algorithmic structure known as an artificial neural network that can mimic the human brain. This enables the systems to be more capable at performing tasks than traditional systems.
However, a deep learning model must continuously be trained to evolve and enhance its capabilities so that it can draw correct conclusions.
