Title:
パラメータテーブルの記憶スペースを削減する方法、装置、デバイス、およびコンピュータ可読記憶媒体
Document Type and Number:
Japanese Patent JP7012766
Kind Code:
B2
Abstract:
Embodiments of the present disclosure relate to a method and apparatus for reducing storage space of a parameter table, a device, and a computer-readable storage medium. The method includes: storing the parameter table in a lookup table system configured to compute an output value of a non-linear function according to an input value of the non-linear function, the parameter table including only an index value associated with an input value on one side of a median in a domain of the non-linear function and a parameter value corresponding to the index value; determining, by using a corresponding relationship between the index value associated with the input value on one side and the parameter value corresponding to the index value, a parameter value corresponding to an index value associated with an input value on the other side; and computing the output value by using the input value on the other side and the determined corresponding parameter value. The technical solution of the present disclosure can reduce the parameter table storage space for the non-linear function in the lookup table system. In addition, the technical solution of the present disclosure is suitable for various fitting methods of the lookup table system, and hardly adds the computing requirements.
