Definition

Machine learning algorithms are computational methods that enable computers to learn from and make predictions or decisions based on data. They analyze patterns in data sets to improve their performance over time without being explicitly programmed for each task. This capability is particularly useful in interpreting complex data, such as detecting atmospheric biosignatures or enhancing the performance of next-generation spectrographs.
