about i3d feature

[menghuaa]

Hello, before linear interpolation, is the feature of I3D extracted at the original frame rate or at the frame rate of 25FPS? 您好，请问在没有线性插值前，I3D的特征是以原始帧频提取的，还是以25fps的帧频提取的？

那请问您，是您自己提的特征吗？

我好像在论文中没有看到您使用i3d特征进行提名生成的结果，请问您使用该i3d特征的提名生成效果怎么样呢？与原始BMN相比

In Table 1(b), we compared the performance differences between SSTAP and BMN.

I3D features do not involve label information in the ActivityNet dataset (v1.2 or v1.3) and only use pre-trained Kinetics information.

请问您是如何将thumos14的数据集划分为有标签数据集和无标签数据集的？我看到thumos14里每个视频的类别数量还是挺多的，不像activitynet1.3那样单一
