Unsupervised learning lets machines learn on their own.

This type of machine learning (ML) grants AI applications the ability to learn and find hidden patterns in large datasets without human supervision. Unsupervised learning is also crucial for achieving artificial general intelligence.
Labeling data is labor-intensive and time-consuming, and in many cases, impractical. That’s where unsupervised learning brings a big difference by granting AI applications the ability to learn without labels and supervision.
What is unsupervised learning?
Unsupervised learning (UL) is a machine learning technique used to identify patterns in datasets containing unclassified and unlabeled data points. In this learning method, an AI system is given only the input data and no corresponding output data.
Unlike supervised learning, unsupervised machine learning doesn’t require a human to supervise the model. The data scientist lets the machine learn by observing data and finding patterns on its own. In other words, this sub-category of machine learning allows a system to act on the given information without any external guidance.
Unsupervised learning techniques are critical for creating artificial intelligence systems with human intelligence. That’s because intelligent machines must be capable of making (independent) decisions by analyzing large volumes of untagged data.
Compared to supervised learning algorithms, UL algorithms are more adept at performing complex tasks. However, supervised learning models produce more accurate results as a tutor explicitly tells the system what to look for in the given data. But in the case of unsupervised learning, things can be quite unpredictable.
Artificial neural networks, which make deep learning a reality, might seem like it’s backed by unsupervised learning. Although it’s true, neural networks’ learning algorithms can also be supervised if the desired output is already known.
Unsupervised learning can be a goal in itself. For example, UL models can be used to find hidden patterns in massive volumes of data and even for classifying and labeling data points. The grouping of unsorted data points is performed by identifying their similarities and differences […]
