Claim 11:
12. A table generating apparatus comprising:
a receiving unit configured to receive a designation of an activation function of a neural network; and
a generation unit configured to generate an approximation table that approximately represents the designated activation function, the approximation table mapping between a plurality of discrete input samples of the activation function and a plurality of output samples, the plurality of output samples respectively corresponding to the plurality of input samples,
wherein the generation unit is configured to set the plurality of input samples of the approximation table such that input samples more distant from a reference point in the domain of the activation function have a larger neighboring sample interval, and
wherein the neighboring sample interval is set such that the neighboring sample interval increases, from a basic sample interval at the reference point as a baseline, by a constant ratio or a constant increment with increasing distance from the reference point.
