In this work, from the collection of portfolio contracts by one insurance year, will be predicted the Customer Lifetime Value of the last three months of the year, also looking at the effects coming from the use of Unsupervised Learning.Unsupervised Learning describes tasks that involves using a model to discover a good internal representation of input data useful for subsequent Supervised Learning. In this job Unsupervised Leaning are used to provide a low-dimensional representation of inputs and clustering numerical variables to provide a better portfolio analysis of customers. In both situations, Unsupervised Learning can be used as feature engineering to improve Machine Learning performances.
