Vision
We can only see a short distance ahead, but we can see plenty
there that needs to be done.

In this last chapter, a short summary of the exemplary results that were selected for
application illustration is given that motivates the vision given in the concluding
section of this topic.
14.1 Summary of Results
Rather than repeating details from the individual sections and formerly derived best
practice recommendations, this summary aims to provide an estimation of applicabil-
ity of systems as they were shown in this topic. By that, let us have a general overview
on the results as were presented in Part III of this topic in a 'less formal' way. In
Table
14.1
results of regression are summarised and in Table
14.2
according results
are presented for classification—the tasks drum-beat separation, onset detection, and
structure analysis were left out due to their more specific testing conditions.
Looking at the results inTable
14.1
, it becomes evident that improvement is needed
in practically any of these, and that human performance level is only reached in some
rare exceptions such as speaker intoxication classification [
1
]. On the other hand side,
any of these tasks are highly significantly above chance level, and many are ready
for first real-life application—given sufficient failure tolerance.
