Neural Network with Confidence Kernel for Robust Vibration Frequency Prediction

Figure 3

Examples of simulated signals: (a) from top to bottom: signal with 6.6 Hz frequency, random noise with a standard deviation of 1.16, and a simulated signal of 6.6 Hz; (b) from top to bottom: signal with 11.6 Hz frequency, random noise with a standard deviation of 2.16, and a simulated signal of 11.6 Hz.
