Calculating device, calculation program, recording medium, and calculation method

A calculation program configured to cause a computer to at least acquire a data set {s}, repeat a processing procedure, and output a fourth function,

• the processing procedure including a first variable update and a second variable update,
• the first variable update including updating an ith entry of a first variable xi by adding a first function to the ith entry of the first variable xi before the first variable update (i being an integer not less than 1 and not more than N, and N being an integer of 2 or more), the ith entry of the first variable xi being one of a first variable set {x}, a variable of the first function including at least a part of a second variable set {y},
• the second variable update including updating an ith entry of a second variable yi by adding a second function and a third function to the ith entry of the second variable yi before the second variable update, the ith entry of the second variable y being one of the second variable set {y}, a variable of the second function including the ith entry of first variable xi and at least a part of the data set {s}, a variable of the third function including at least a part of the first variable set {x} and at least a part of the first parameter set {J},
• a variable of the fourth function including at least a part of the first variable set {x} obtained after repeating the processing procedure and the second variable set {y} obtained after repeating the processing procedure.

A recording medium, the recording medium being computer-readable, a calculation program being recorded in the recording medium, the calculation program configures to cause a computer to at least acquire a data set {s}, repeat a processing procedure, and output a fourth function,

• the processing procedure including a first variable update and a second variable update,
• the first variable update including updating an ith entry of a first variable xi by adding a first function to the ith entry of the first variable xi before the first variable update (i being an integer not less than 1 and not more than N, and N being an integer of 2 or more), the ith entry of the first variable xi being one of a first variable set {x}, a variable of the first function including at least a part of a second variable set {y},
• the second variable update including updating an ith entry of a second variable yi by adding a second function and a third function to the ith entry of the second variable yi before the second variable update, the ith entry of the second variable yi being one of the second variable set {y}, a variable of the second function including the ith entry of first variable xi and at least a part of the data set {s}, a variable of the third function including at least a part of the first variable set {x} and at least a part of the first parameter set {J},
• a variable of the fourth function including at least a part of the first variable set {x} obtained after repeating the processing procedure and the second variable set {y} obtained after repeating the processing procedure.
