...A series of approaches incorporate missing feature theory and aim to generate time-frequency masks that indicate spectrotemporal regions that belong only to a particular instrument which can then be classified more accurately since regions that are corrupted by noise or interference are kept out of the classification process [42, 53]....

...The success of this task is then intimately connected to the efficiency of the extraction of multiple fundamental frequencies, which is known to be a very difficult problem, especially for octave-related notes....

...However, identifying instruments from complex mixtures involving more than one playing at a time remains a very difficult problem that has been addressed in a very few studies [2], [3], [4], [5], [6] with often important restrictions regarding the musical content with respect to instruments involved and played notes....

...Here, we assume a diagonal covariance matrix; although this embodies an assumption which is incorrect (independence of features) it is a widely used simplification (e.g., see [1])....

...Secondly, although cepstral coefficients have been used successfully as features for instrument identification [1], [6], they are not used here because they do not fit naturally into the missing feature approach....
