LiteEval: A Coarse-to-Fine Framework for Resource Efficient Video Recognition
[article]
2019
arXiv
pre-print
Preserved Fulltext
This paper presents LiteEval, a simple yet effective coarse-to-fine framework for resource efficient video recognition, suitable for both online and offline scenarios. ...
This is achieved by a coarse LSTM and a fine LSTM operating cooperatively, as well as a conditional gating module to learn when to allocate more computation. ...
We introduce LITEEVAL, a resource-efficient framework suitable for both online and offline video classification, which adaptively assigns computational resources to incoming video frames. ...
