With a view to having a fair comparison, the baseline system was implemented with two different decision trees for F0 trajectories, one for the voicing labels and the other for the output probability distributions.
The data are interpreted as reflecting two different decision processes: an identification process based on local lexical activity underlying the 'yes' response to words, and a temporal deadline process underlying the 'no' response to non-words based on global lexical activity.
Pareto frontier is obtained for triple and dual objectives and the best optimal value is selected through four different decision making techniques viz.
Chemical categories were identified for four different decision contexts chosen to cover realistically possible read-across situations, as listed in Table 1.
