Here is a worked example of a perceptron applied to the task of lexical selection. Lexical selection is the task of choosing a target translation t
for a given source word s
in a context C
out of a set of possible translations T
. A perceptron makes a classification decision for a single class, so we need to train a separate perceptron for each possible target word selection.
