Yunpeng Li, Dominik Roblek e Marco Tagliasacchi. Daqui para lá: Vídeo entre o uso de convoluções Direct 3D, 2019.

https://arxiv.org/abs/1905.10240

Características atuais do hub:

  • tem modelos para vídeos de envio de robôs BAIR e conjunto de dados de vídeo de ação KTH (embora esta colab use apenas BAIR)
  • Conjunto de dados BAIR já disponível no Hub. No entanto, os vídeos KTH precisam ser fornecidos pelos próprios usuários.
  • apenas avaliação (geração de vídeo) por enquanto
  • o tamanho do lote e o tamanho do quadro são codificados permanentemente

Configurar

Desde tfds.load('bair_robot_pushing_small', split='test') iria baixar um arquivo de 30GB, que também contém os dados de treinamento, nós baixar um arquivo separado que contém somente os dados de teste 190MB. O conjunto de dados utilizado foi publicada por este trabalho e é licenciado como Creative Commons BY 4.0.
