    Learning Deep Latent Spaces for Multi-Label Classification

    Full text link
    Multi-label classification is a practical yet challenging task in machine learning related fields, since it requires the prediction of more than one label category for each input instance. We propose a novel deep neural networks (DNN) based model, Canonical Correlated AutoEncoder (C2AE), for solving this task. Aiming at better relating feature and label domain data for improved classification, we uniquely perform joint feature and label embedding by deriving a deep latent space, followed by the introduction of label-correlation sensitive loss function for recovering the predicted label outputs. Our C2AE is achieved by integrating the DNN architectures of canonical correlation analysis and autoencoder, which allows end-to-end learning and prediction with the ability to exploit label dependency. Moreover, our C2AE can be easily extended to address the learning problem with missing labels. Our experiments on multiple datasets with different scales confirm the effectiveness and robustness of our proposed method, which is shown to perform favorably against state-of-the-art methods for multi-label classification.Comment: published in AAAI-201

    This study examines the correlation between risk perception, knowledge, social influence, self-efficacy, and cyber bullying behavior from the perspective of the attitude-social influence-efficacy model. The samples in this survey are adolescents who have had cyber bullying behavior or have witnessed their peers’ cyber bullying behavior. The results showed that attitude towards cyber bullying affected cyber bullying intention, and that intention also influenced cyber bullying behavior. Social influence also had an impact on cyber bullying intention and cyber bullying behavior. In fact, intention was a mediator between attitude and behavior, as well as between social influence and behavior. Este estudio examina la correlación entre la percepción de riesgo, el conocimiento, la influencia social, la autoeficacia y el comportamiento del acoso cibernético desde la perspectiva del modelo de influencia social. Las muestras en esta encuesta son adolescentes que han tenido un comportamiento de acoso cibernético o han presenciado el comportamiento de acoso cibernético de sus compañeros. Los resultados mostraron que la actitud hacia el acoso cibernético afectó la intención de acoso cibernético, y esa intención también influyó en el comportamiento del acoso cibernético. La influencia social también tuvo un impacto en la intención de acoso cibernético y el comportamiento de acoso cibernético. De hecho, la intención era un mediador entre la actitud y el comportamiento, así como entre la influencia social y el comportamiento

    Absorptive Capacity And MNC Knowledge Transfer: The Organizational Behavior Perspective

    Get PDF
    Many previous studies on internal knowledge transfer in multinational corporations (MNCs) have indicated that organizational absorptive capacity (AC) has a significant effect on knowledge transfer, but few scholars have dwelt on employee absorptive capacity. Employee AC is fundamental to organizational AC. Therefore, employee AC is an important management issue. From an organizational behavior perspective, this study attempted to explore whether employees personality traits, job characteristics and organizational environment had an impact on their absorptive capacity, hoping to develop a new research direction for the AC research realm

    The Effect Of Blog Trustworthiness, Product Attitude, And Blog Involvement On Purchase Intention

    Get PDF
    Consumers value the advice of others when they are shopping online. Therefore, some high pageview bloggers could have a great influence on a consumer’s shopping decision. Blog marketing is a new communication tool. “Blog trustworthiness”, “product attitude” and “blog involvement” were the three independent variables used in this study to investigate the aspect of purchase intention. This study found that blog involvement had a significant influence on purchase intention. This result contributes concrete suggestions to enterprises when they are dealing with blog marketing
