Look inside
In this liveProject, you’ll use the Julia language and clustering algorithms to analyze sales data and determine groups of products with similar demand patterns. Clustering is a well-established unsupervised learning technique that’s commonly used to discover patterns and relations in data. You’ll apply k-means and DBSCAN clustering techniques to housing sales data for a retail startup, leveraging your basic Julia skills into mastery of this machine learning task.
This project is designed for learning purposes and is not a complete, production-ready application or solution.
