    Introducing Social Perception

    505
    Perceiving others accurately is fundamental to effective communication and relationship-building. Social perception, a key concept in social psychology, refers to the cognitive processes through which individuals gather and interpret information about others to understand their actions, intentions, and motivations. This process extends beyond spoken words and overt behaviors, incorporating subtle nonverbal cues and contextual factors.Nonverbal Cues and Their SignificanceNonverbal cues play a...

    This study introduces a novel deep matrix factorization algorithm for social image understanding. It effectively refines, assigns, and retrieves tags by integrating visual and semantic data, overcoming noisy user tags.

    Area of Science:

    • Computer Science
    • Artificial Intelligence
    • Machine Learning

    Background:

    • Social image databases have grown, but user-provided tags are often incomplete, subjective, and noisy.
    • Existing methods struggle with the semantic gap and noisy data in social image understanding tasks.

    Purpose of the Study:

    • To develop a novel weakly supervised deep matrix factorization algorithm for social image understanding.
    • To address challenges in tag refinement, tag assignment, and image retrieval with noisy user tags.

    Main Methods:

    • A deep matrix factorization algorithm is proposed, exploring tagging information, visual, and semantic structures.
    • A hierarchical model learns latent image representations, bridging the visual feature space and semantic subspace.
    • Joint incorporation of semantic and visual structures and a sparse model mitigate overfitting and noisy features.
