WebFITC Approximation. In all the examples we give there will be 100 points in the active set. We first considered the FITC approximation. The script demOilFgplvm1.m runs the FITC approximation giving the result on the left of the figure shown below. Left: GP-LVM on the oil data using the FITC approximation without back constraints. The phases of ... WebOct 9, 2024 · The FITC approximation will give us the real posterior if the inducing points are placed at the data points, but optimising the locations of the inducing points will not necessarily help. In fact, Alex demonstrated that even when initialised at the perfect solution \(\mathbf Z = \mathbf X\), the FITC objective encourages \(\mathbf Z\) to move ...
