Using evotrees.jl for time series prediction

Introduction In this post, I want to show an analysis of a time series that I’ve been working on. Usually, when dealing with time series, it is not so common to use machine learning algorithms (without at least trying more traditional models like the ARIMA family), but I still wanted to test how well a GBM model fits for these kinds of problems that are so popular. NOTE: I don’t recommend starting with models of this type for time series problems.

How to scrape data with Python using selenium and Pandas

Introduction In this tutorial, I will dedicate myself to explaining how web scraping can be done from a platform where a dynamic interaction of the web application is required, this is quite useful when obtaining data from different links within the platform and where it is necessary a management scheme of the front-end components to carry it out. Here there are mainly two essential libraries, the first is selenium which corresponds to a framework that operates for multiple languages and serves to automate and control the browser, while Pandas for data manipulation will allow us to read data tables directly.

World Happiness Report - EDA & clustering with Julia

The purpose of this post is to show Julia as a language for data analysis and Machine Learning. Sadly Kaggle does not support Julia Kernels (hopefully, they will add it in the future). Therefore I wanted to take advantage of this space to show a reimplementation of Python/R Notebooks to Julia. In this context, I took data on happiness in countries in 2021 and some factors considered in this exciting survey.

Why have I decided to open a blog?

Introduction The purpose of starting this blog is to create a space where I can write about topics that interest me related to technology, the world of quantitative methods for decision making, programming, among others. But why create a blog, if there are so many spaces out there that are more convenient than building one? The truth is, I wanted to have a more independent space and not too comfortable on third parties (nor benefit them), although there are spaces like Twitter (which seems to be in greater decline every day) or Medium, I simply thought that the best thing I could do is to have a personal space, and given that the dream of owning a house seems to be increasingly distant for my generation, well at least I can settle for having a blog, right?
