Patent ID: 11881881
Assignee: RICOH COMPANY, LTD.
Field: Medical technology (Instruments)
Classification: CPC H  A | IPC A  H

Claim 0:
1. A determination apparatus comprising:
a sensor to detect signals and which outputs a mixed signal which has been detected including biomedical signals from a subject and an interference signal:
circuitry configured to:
compare signal separation results obtained by a plurality of signal separation algorithms including two or more algorithms from a group including a dual signal subspace projection (“DSSP”) method, a temporally extended signal space separation (“tSSS”) method, and principal component analysis (PCA)/independent component analysis (ICA) executed on the mixed signal in which signals emitted from a plurality of signal sources are mixed, each of the plurality of signal separation algorithms being an algorithm separating a signal of interest from the mixed signal; and
determine a parameter of each of the plurality of signal separation algorithms based on a comparison result,

wherein the circuitry determines the parameter of each of the plurality of signal separation algorithms at which each of the signal separation results is within a predetermined error range as the parameter of each of the plurality of signal separation algorithms.
