Table 19: Number of turns for which each Run outperformed the others for the Japanese data
['a subset of turns  [ITALIC] V′ (⊂ [ITALIC] V)', '| [ITALIC] V′|']
V denotes the set of target system utterances in the evaluation dataset, and msei(v) denotes the MSE of Run i given a target system utterance v (∈V). V1<3,5, V3<1,5, and V5<1,3 are defined by the following equations: Run 5 outperformed the other runs is relatively small. The x-axis is mse1(v)−mse5(v), and the y-axis is mse3(v)−mse5(v). The points coloured in blue, orange, and green denote the target system utterances that match the condition of V1<3,5, V3<1,5, and V5<1,3 respectively.
