Artificial neural networks are used to develop various innovations, such as how Google can translate paragraphs into another language in milliseconds. They are also being used to improve the recommendations of YouTube and Netflix.
Deep learning is a type of machine learning that uses artificial neural networks to learn from large datasets. Let’s discuss the basics of deep learning, including what it is and how it works.
What Is Deep Learning?
Deep learning is essentially a subset of artificial intelligence, a kind of machine learning inspired by the human brain. Machine learning is a set of algorithms designed to mimic human behavior using data. Deep learning aims to draw parallels between humans and data by continuously analyzing it with logical structures. This process is carried out through a multi-layered structure known as neural networks.
The design of deep learning’s neural network is based on how the human brain works. Similar to how we use our brains to classify and identify information, we can teach these networks how to perform the same task on data. With the help of neural networks, we can perform various tasks, such as clustering and classification. For instance, we can group unlabeled data into different categories based on their similarities.
How Does Deep Learning Work?
Like the human brain, deep learning’s neural networks are composed of nodes, similar to the structure of neurons. Each node is connected to an adjacent layer. The number of layers in the network determines its depth.
The signals that travel between nodes in a deep learning network are then assigned weights. The heavier nodes are then used to exert more influence on the network’s next layer. The last layer of the network then compiles the outputs of the weights. Deep learning systems are incredibly complex because they have much to process.
Due to the complexity of deep learning algorithms, they need large amounts of data to perform their tasks. When processing the data, the networks can identify and classify it using complex mathematical calculations.
A facial recognition program uses deep learning to learn how to identify and detect lines and edges of faces. It then trains itself to improve accuracy by learning more significant parts of the face. Over time, the program will be able to recognize faces accurately.
