Cluster then predict

WebIf we first cluster the microseism data and then use the machine learning method to establish the prediction model, we will get better results. Therefore, we propose to combine clustering analysis and machine learning methods to predict the high-energy mine earthquake in time sequence, including the occurrence location prediction and energy ... WebNov 19, 2011 · It takes a two dimensional data and organises them into clusters. Each data point also has a class value of either a 0 or a 1. What confuses me about the algorithm is how I can then use it to predict some values for another set of two dimensional data that doesn't have a 0 or a 1, but instead is unknown.
