Weakly Supervised Action Localization

In the field of computer vision, the task of weakly supervised action localization aims to train algorithms using video activity data without annotated temporal boundaries, so that they can identify specific activities in videos and accurately provide their start and end times during testing. This task significantly reduces the cost of data preparation by decreasing the reliance on large amounts of finely annotated data, while also enhancing the model's generalization capabilities in real-world applications, making it of great research and application value.
