What are some examples of the industry of unsupervised learning?
Clustering analysis and other forms of unsupervised learning are used throughout the industry, including healthcare, finance, retail and manufacturing.
In healthcare, clustering helps identify patient populations with similar health characteristics or treatment responses.
“Clustering allows you to group patients based on historical data and design interventions tailored to each group,” says Purcell.
Financial services are used to detect fraud by identifying abnormal patterns that deviate from the standard (an application known as anomaly detection).
“Unsupervised learning is especially useful in identifying activities that don't fit existing rules but may still be suspicious,” adds Purcell.
In retail and e-commerce, clustering allows for more effective customer segmentation by analyzing purchase behavior, browsing history and demographic data.
“Retailers can create micro-courses for their customers and personalize their marketing strategies,” he says.

How can clustering insights help your organization?
The core value of unsupervised learning and clustering lies in its ability to uncover insights that could otherwise remain hidden.
Once data is organized, IT leaders can use it for predictive analytics and business intelligence. For example, companies that find that a particular customer segment is much more price sensitive than other segments will offer targeted discounts only to that group, improving their marketing ROI.
Unsupervised machine learning can also help build robust AI models, especially when labeled data is rare or expensive to obtain.
Purcell said these capabilities are especially important when agility, adaptability and insight are key to staying competitive.
“Organisations sit in a pile of data, many of which are invalid and unused,” says Purcell. “Clustering analysis helps make that data useful by organizing it into understandable groups.”
