“…Severe missing values can result in inaccurate forecast values. A similar phenomenon was reported by Fernandes et al [ 43 ], which they refer to as the “misalignment problem in matrix factorization with missing values”. This problem is illustrated in Figure 5 : even though the nonnegative matrix factorization captures accurately the evolution of the time series in the missing gaps, the estimated range of values is far from the actual range of values.…”
