Application: Softmax function approximation calculation device, approximation calculation method, and approximation calculation program (Patent ID: US20240104166A1)

The patent filed by Konica Minolta Inc. describes a softmax function approximation calculation device that uses integers or fixed-point numbers as input data to calculate softmax function values. The device involves subtracting a common numerical value from the input data to generate divided data, which is then used to access look up tables storing approximate values of exponential function values. These approximate values are multiplied and divided to calculate the softmax function value. The device aims to reduce the size of look up tables required for approximation calculations while minimizing errors.

The device includes components such as a subtractor, divided data generator, storage for look up tables, acquisitor, multiplier, and approximation calculator. The subtractor calculates the difference value, the acquisitor retrieves approximate values from the look up tables, and the multiplier calculates multiplication values. The device ensures that the difference value is 0 or less for all input data pieces by setting the common numerical value as the maximum input data. Additionally, rounding and right shift operations are used to equalize the number of bits during multiplication. The device also includes a quantizer to convert floating-point numbers to integers or fixed-point numbers for input data. Overall, the device provides an efficient method for approximating softmax function values using a fixed-point number or integer input data, reducing the required size of look up tables and minimizing errors in the calculation process.
