Yelp Open Dataset is a collection of data concerning users who write reviews on businesses belonging to different commercial categories (e.g. restaurants, car rental, etc. …). Thanks to this database I was able to realize a model based on a neural network for the automatic classification of reviews using natural language processing and machine learning […]

What is the Facebook Hacker Cup? The Facebook Hacker Cup is a competition for programmers promoted by Facebook worldwide. The aim of the competition is to find the best programmers in the world to whom to pay cash prizes. The final winner will also win the cup. The problems proposed during the Facebook Hacker Cup […]

Erlang is one of the functional programming languages that allows you to build concurrent programs in a relatively simple way; its actor-based paradigm offers primitives to create processes and make them communicate with each other in a way that other languages do not. Another peculiarity of Erlang, probably the most important one, is the possibility […]

In this article I describe what was my project for the master’s thesis in Computer Science at the University of Bologna, in which I was involved in using the technologies of Deep Convolutional Neural Networks to create models of machine learning that were able to detect cases of COVID-19 by analyzing voice recordings. In the […]
