We plan to use {\it machine learning} and {\it deep learning} tools in the analysis of large photometric and spectroscopic surveys, such as S-PLUS, J-PLUS, J-PAS and PFS, to extract the information contained in the large datasets that are or will be generated by these projects. Our initial focus is the analysis of the data that S-PLUS has been obtaining, but the techniques will be applied later to the J-PLUS, J-PAS and PFS projects. For this we will invest both in the implementation of algorithms and in the preparation of training sets suitable for our scientific purposes. The results of the project, such as photometric redshifts and parameters describing properties of stellar populations of galaxies, will be useful for many applications. (AU)
