moving windows

Terms from Artificial Intelligence: humans at the heart of algorithms

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

When applying windowing techniques in time series or sequential data moving windows takes windows of a fixed length starting at every position, for example [1,2,3,4], [2.3.4.5], [3.4.5.6], etc. This is in contrast to non-overlapping windows.
Moving windows are often used when wanting to make a prediction of the item following the window, for example, predicting data point 5 based on points 1 to 4. In time-series analysis moving averages do this with simple linear predictors, often over a small number of past observations. Large-language modles use the same technique but with a deep neural network to perform the prediction and a window size that is many thousands, if not millions of tokens long.
