Function overloading is a very interesting tool that allows several different functions to share the same identifier, improving the readability and interpretability of our code in some scenarios. This tool is available by default in many of today’s most widely…
This post will deal from another point of view with one of the most popular games that can be played on paper, the Sudoku. The objective will be to explain an algorithm for solving it, together with the code that…
In other discussion spaces we elaborated a comparison between DBT, Pentaho and Spark to perform data transformations. In this post, we will look at some of the key concepts of DBT: models, snapshots and materializations. In the context of DBT…
In two previous posts we introduced the basic concepts of Fuzzy Logic and linear programming with the Simplex method. As promised, in this post we are going to join these two concepts and introduce fuzzy linear programming. In many real-world…
BigQuery has become in recent years a powerful tool for data storage and analysis in the cloud. Its size, scalability and all the features it offers would be difficult for a user or company to replicate from scratch due to…
Modeling and explaining the consumer behavior of a product is very important to know what factors affect their behavior, price being one of these important factors. Let’s take as an example a company X that sells clothing. It is a…
Software tests are tests that are performed on a piece of code or an entire software to validate that the behavior of the software is as expected. The main purpose of testing is to detect errors in the code in…
A linear regression is a model that is used to approximate the linear relationship between a dependent variable Y and a set of independent variables X. In matrix format it can be expressed as where ε is a vector of…
We know that there is a large number of products in the data engineering ecosystem to perform the data processing of a company and that most of them provide the necessary tools to be able to perform many types of…
Introduction All graphics in this article are interactive due to the nature of trying to represent text graphically. To see which sentence each point represents, simply hover the mouse over it. The results obtained have been generated on the “STS…
