surrogate expert

Terms from Artificial Intelligence: humans at the heart of algorithms

The glossary is being gradually proof checked, but may have typos and misspellings.

Sometimes a machine learning algorithm or other form of AI may be used as a surrogate expert, to make parameter choices about statistical technigues or neural network architectures; choices that would otherwise be made by a statistical or AI expert. For example, in time series analysis one needs to decide how many time steps to use in windowing methods such as ARMA.
