Classification: CPC G  H | IPC G  H

Claim 6:
7. A circuit, comprising:
a lookup table access unit configured to determine a function value of a first activation function corresponding to an input value of the first activation function by referring to a shared lookup table that includes a plurality of function values of the first activation function,
wherein the shared lookup table includes at least a plurality of function values of a Sigmoid function or of a Hyperbolic tangent function;
an input value conversion unit configured to convert an input value of a second activation function into the input value of the first activation function in a predetermined mode based on the plurality of function values of the first activation function included in the shared lookup table, the second activation function being a different function than the first activation function; and
a function value conversion unit configured to convert the function value of the first activation function into a function value of the second activation function in the predetermined mode,
wherein the lookup table access unit, the input value conversion unit, and the function value conversion unit are implemented using one or more hardware processors and a memory.
