Why the epochs for RGB modality is so large? #36

Closed kylemin closed 6 years ago

kylemin commented 6 years ago

The original paper uses 4500 iterations in total.

yjxiong commented 6 years ago

UCF101 has around 6000 videos for training. So one epoch is around 50 iterations. 90 epochs are around 4500 iterations. So it is similar to the paper. Please be aware that the concept of the epoch is defined against videos, not frames.

So that means each batch can have frames from multiple videos? Like, 1 batch = 3 frames * 128 videos?
