WebLarge scale classification using the FITC approximation. In case the number of training inputs x exceeds a few hundreds, approximate inference using infLaplace.m, infEP.m and infVB.m takes too long. As in regression, we offer the FITC approximation based on a low-rank plus diagonal approximation to the exact covariance to deal with these cases. WebMar 1, 2024 · For reducing the computational complexity in dynamical modeling, an FITC approximation was generally used in the literature (e.g. [19], [20]). The limitation of the FITC approach is that it is prone to overfitting and underestimates the predicted variance [21].
