Unit: How does Deep Learning Relate to AI?
Section: AI vs. Machine Learning vs. Deep Learning

Artificial Intelligence

Artificial Intelligence (AI) refers to the way machines mimic intelligence and human decision making. “AI” is a general term that refers to a wide array of different applications! 

 

Whether it be self-driving cars, chat-bots, virtual assistants like Apple’s Siri, face-recognition software, and much more, all these diverse applications share one thing in common: they take some data, or inputs, and make an “intelligent” decision, or output.

Machine Learning

Machine Learning is a subset of AI, referring to the specific way machines use computer algorithms to find patterns in data for some meaningful purpose, such as to learn or make predictions. This will be the focus of the next section of lessons.

Using Data to Find Patterns

Deep Learning

Deep Learning is a subset of machine learning, and refers to the way machines mimic the human brain to find and utilize patterns in data. Taking the world by storm, the most famous AI application like Chat-GPT and DALL-E all utilize deep learning to create realistic “human” behavior. The infrastructure used to create deep learning models are called neural networks, named after the neural connections of the human brain. 

 

There are many types of neural networks, such as convolutional neural networks (CNNs), recurrent neural networks (RNNs), and generative adversarial networks (GANs), but the main focus of this website will be fully connected neural networks, the most basic but widely-used neural network. It can be thought of as the elementary building block of other specialized networks, Therefore, the concepts you will learn will nearly always be applicable to other networks.

Simple Neural Network - Data Transformation (You will see this animation in the "Supervised Machine Learning" Lesson. For now, as the data is being passed from "neuron" to "neuron," it is being transformed in some way)

Ultimately, as seen by the graph below, the main takeaway is that deep learning is a subset of machine learning, which is a subset of AI.
