The three variants are: SkipDelta: ht−1−ht−3 DoubleDelta: [ht−1−ht−2;ht−2−ht−3] Hadamard Product: ht−1∗ht−2 The reason to use SkipDelta and DoubleDelta is because we want to see if there is any benefit to incorporate longer (or more) dialog history. Experiment results show while using longer dialog history (i.e., SkipDelta) helps, adding too many dialog history (i.e., DoubleDelta) does not give any improvement.
