Predictions with MGPs model for two oscillating signals. (a and b) Dashed lines represent true behaviour of noiseless trajectories; dots correspond to the noisy observations for both signals (data); solid lines are the mean behaviour of the MGPs model (predictions with original GPs); light areas correspond to two standard deviations at each prediction point. (c and d) Dashed lines represent true behaviour of noiseless trajectories; solid lines show the mean behaviour of the MGPs model (predictions with derivative processes); light areas correspond to two standard deviations at each prediction point
