Hypotheses Tree Building for One-Shot Temporal Sentence Localization

AAAI 2023technical

Given an untrimmed video, temporal sentence localization (TSL) aims to localize a specific segment according to a given sentence query. Though respectable works have made decent achievements in this task, they severely rely on dense video frame annotations, which require a tremendous amount of human…

Memory-Guided Semantic Learning Network for Temporal Sentence Grounding

AAAI 2022technical

Temporal sentence grounding (TSG) is crucial and fundamental for video understanding. Although existing methods train well-designed deep networks with large amount of data, we find that they can easily forget the rarely appeared cases during training due to the off-balance data distribution, which i…

Rethinking the Video Sampling and Reasoning Strategies for Temporal Sentence Grounding

EMNLP 2022finding

Temporal sentence grounding (TSG) aims to identify the temporal boundary of a specific segment from an untrimmed video by a sentence query. All existing works first utilize a sparse sampling strategy to extract a fixed number of video frames and then interact them with query for reasoning.However, w…

Unsupervised Temporal Video Grounding with Deep Semantic Clustering

AAAI 2022technical

Temporal video grounding (TVG) aims to localize a target segment in a video according to a given sentence query. Though respectable works have made decent achievements in this task, they severely rely on abundant video-query paired data, which is expensive to collect in real-world scenarios. In this…
