In recent years much progress has been made in solving complex problems thanks to Artificial Intelligence algorithms. These algorithms need a large volume of information to discover and learn, continuously, hidden patterns in the data. However, this is not the way the human mind learns. A person does not require millions of data and multiple iterations to solve a particular problem, since all they need are some examples to solve it. In this context, techniques such as semi-supervised learning or semi-supervised learning are playing an important role nowadays. Within Machine Learning techniques, we can find several well-differentiated approaches (see Figure 1). The supervised algorithms deal with labeled data sets and their objective is to construct predictive models, either classification (estimating…

Identification and analysis of signs of customer churn Knowing which customers might not continue as such has been the objective of classic customer churn models, which final output consisted of the probability of loss associated with each customer over a specific temporary time range. However, once we know the customer is going to leave, we must ask ourselves: What can we do to keep them? And taking it even further: What can we do to keep the customer from even considering leaving? Preventive Measures for Customer Churn in the Banking Sector At Synergic Partners, we have carried out a project for one of the largest banking entities in Spain responding to these questions with a methodology based on the combination…
