Temporally-language-grounding

A Pytorch implemention for some state-of-the-art models for "Temporally language grounding in untrimmed videos"

Requirements

• Python 2.7
• Pytorch 0.4.1
• matplotlib
• The code is for Charades-STA dataset.

Three Models for this task

Supervised Learning based methods

• TALL: Temporal Activity Localization via Language Query
• MAC: MAC: Mining Activity Concepts for Language-based Temporal Localization.

Reinforcement Learning based method

• A2C: Read, Watch, and Move: Reinforcement Learning for Temporally Grounding Natural Language Descriptions in Videos.
