Gesticulator: BVH files from the ablation study

BVH files corresponding to the motions for the full model and all 6 different ablations, which were used in the ablation study for the ICMI 2020 paper "Gesticulator: A framework for semantically-aware speech-driven gesture generation"Note that we discovered an issue with the velocity loss implementation used for our experiments. The bug was fixed in this commit. The experimental results involving velocity loss were hence not correct and should be disregarded.本数据集包含对应完整模型及全部6种消融实验（ablation）的运动的BVH文件，这些数据被用于ICMI 2020年会论文“Gesticulator：语义感知型语音驱动手势生成框架”所开展的消融研究。请注意，我们发现实验中所使用的速度损失（velocity loss）实现方案存在一处缺陷，该漏洞已在本次代码提交中修复。因此所有涉及速度损失的实验结果均不准确，应予以忽略。
