Figure 7. Impact of the model validation strategy on the performance of the CNN (decision windows of 1 s).

Figure 7.

In Leave-one-story+speaker-out, the training set does not contain examples of the speakers or stories that appear in the test set. In Every trial (unprocessed), the training, validation, and test sets are extracted from every trial (although always disjoint), and no spatial filtering takes places. In Every trial (per-trial MWFs), data is again extracted from every trial, but this time per-trial MWF filters are applied. CNN = convolutional neural network.
