    This study introduces a novel semisupervised feature selection method for video semantic recognition. It jointly learns the optimal graph structure and selects features, improving recognition accuracy and robustness.

    Area of Science:

    • Computer Science
    • Artificial Intelligence
    • Machine Learning

    Background:

    • Video semantic recognition faces challenges like high dimensionality and limited labeled data.
    • Existing semisupervised methods often rely on predetermined graphs, which can be suboptimal and suffer from dimensionality issues.
    • The separation of graph construction and feature selection can hinder performance.

    Purpose of the Study:

    • To develop a novel semisupervised feature selection method for video semantic recognition.
    • To address the limitations of predetermined graphs and the curse of dimensionality.
    • To enhance the robustness and efficiency of video semantic recognition models.

    Main Methods:

    • A new model that jointly learns the local structure (graph) and performs feature selection.
