Résumé :
Machine Learning (ML) strategies have been shown to be extremely efficient to find patterns in huge amount of data. That makes it important in a broad area of science, including economy, biology, physics and many other fields of knowledge. Recently, the use of ML techniques to solve physical problems has grown significantly [1-5]. Here, we will present a brief review on the advancement in the use of ML strategies when applied to physical problems. We will focus mainly on quantum phase transitions [6, 7] and we will present our new findings concerning the one-dimensional spin-1/2 Ising model with nearest and next-nearest-neighbour interactions in the presence of a transverse magnetic field.
