Claim 19:
20. A computing system, comprising:
one or more processors; and
a non-transitory, computer-readable medium comprising instructions that, when executed by the one or more processors, cause the one or more processors to perform operations, the operations comprising:
inputting a video into a machine-learned model comprising one or more weakly supervised temporal action localization models;
analyzing the video by the one or more weakly-supervised temporal action localization models to determine one or more weighted temporal class activation maps; and
determining a temporal location of a target action in the video based at least in part on the one or more weighted temporal class activation maps;
wherein the machine-learned model comprises a sparse temporal pooling network comprising a first weakly supervised temporal action localization model and a second weakly supervised temporal action localization model.
