Customer segmentation using OPTICS algorithm Kaggle

WebSep 21, 2024 · K-means clustering is the most commonly used clustering algorithm. It's a centroid-based algorithm and the simplest unsupervised learning algorithm. This algorithm tries to minimize the variance of data points within a cluster. It's also how most people are introduced to unsupervised machine learning. WebThe clustering of the data was done through k-means on a pre-processed, vectorized version of the literature’s body text. As k-means simply split the data into clusters, topic modeling through LDA was performed to identify keywords. This gave the topics that were prevalent in each of the clusters.
