Application: Signal/noise determination apparatus, method, and recording medium (Patent ID: US20230417812A1)
The patent filed by Advantest Corp. describes a signal/noise determination apparatus that includes sensors to measure signal and noise, a determination model recording section, and a signal/noise determining section. The determination model is generated through machine learning using training data of measurement results, hypothetical signal information, and hypothetical noise information. This model is used to determine whether components of the measurement results are from a signal source or a noise source based on the position of the signal and noise sources.
The apparatus assumes the signal source is within a predetermined region and the noise source is around that region. The components of the measurement results can be obtained through independent component analysis, principal component analysis, or FFT. Machine learning is based on a convolutional neural network with activation functions like sigmoid or Softmax. The signal can be represented as a magnetic dipole moment or a current dipole moment. Additionally, the patent also covers a signal/noise determination method and a computer-readable medium with instructions for executing the signal/noise determination process using the described apparatus.
