We live in an era of environmental deterioration through depletion and degradation of resources such as air, water, and soil; the destruction of ecosystems and the extinction of wildlife. As a matter of fact, environmental degradation is one of three main threats identified in 2004 by the High Level Threat Panel of the United Nations, the other two being poverty and infectious diseases. In particular, air pollution ranked seventh on the worldwide list of risk factors, contributing to approximately three million deaths each year.

"Geochemical biodegraded oil classification using a machine learning approach"

Chromatographic oil analysis is an important step for the identification of biodegraded petroleum via peak visualization and interpretation of phenomena that explain the oil geochemistry. However, analyses of chromatogram components by geochemists are comparative, visual, and consequently slow. This article aims to improve the chromatogram analysis process performed during geochemical interpretation by proposing the use of convolutional neural networks (CNN), which are deep learning techniques widely used by big tech companies. Two hundred and twenty-one (221) chromatographic oil images from different worldwide basins (Brazil, USA, Portugal, Angola, and Venezuela) were used. The open-source software Orange Data Mining was used to process images by CNN. The CNN algorithm extracts, pixel by pixel, recurring features from the images through convolutional operations ...
