  • Research on Extraction Technology Based on Remote Learning
    CAO Cong-hui LAN Qiang HOU Qun QI Wei-min

     With the development of Internet technology, the explosive growth in the number of text has brought some troubles in pro-
    cessing text data. The traditional text clustering and keyword extraction technology cannot solve the need for precise screening of
    large data very well. This paper combines text clustering and keyword extraction. The text clustering based on LDA algorithm is pro-
    posed. The results of clustering and the subject terms extracted from LDA are obtained. Then the FP-growth algorithm is used to ana-
    lyze the results of the LDA algorithm, and the text is mined. In this paper, according to the idea of using the network knowledge
    base, the Baidu encyclopedia is used to put forward the Chinese comparison algorithm to select the Chinese keyword set and filter
    out a lot of noise words. Experimental results show that the method can cluster text and extract keyword perfectly for a given Chi-
    nese corpus by comparing with the existing method. On the basis of increasing the word selection of Baidu encyclopedia, the accura-
    cy of the system is greatly improved.

    Abstract ( )   Knowledge map   Save
    Owing to labeling training samples are often hard to be collected and subject to a significant amount of human labor or costs, in this paper, a semi-supervised linear subspace learning approach via sparse coding is proposed. Our method can combine labeling samples and unlabeled samples to train a semi-supervised model. First, we train the samples to obtain the structured dictionary and the sparse representation feature; then we group them for more discriminative part (MDP) and less discriminative part (LDP). Finally, we learn the semi-supervised projection matrix P. The experimental results show that the proposed method can improve the classification results on the face image databases extended Yale B and AR datasets.
