Machine learning

Definition

Machine learning is a subset of artificial intelligence that involves the development of algorithms and statistical models that enable computers to learn from and make predictions based on data. This technology allows for the analysis of complex datasets, identifying patterns and making informed decisions without being explicitly programmed. In the realm of biogeochemical research, machine learning can enhance the understanding of environmental processes by processing large volumes of data, leading to improved predictions and insights.
