Short text differs from traditional documents in its shortness and sparseness. Feature extension can ease the problem of high sparseness in the vector space model, but it inevitably introduces noise. To resolve this problem, this paper proposes a high-frequency feature expansion method based on a latent Dirichlet allocation (LDA) topic model. High-frequency(More)
For failure analysis, most of defects are visible to imaging tools, such as OM, SEM, FIB, TEM etc. However, there are still lots of non-visible defects which cannot be caught by these tools. As complexity for such non-visible defect failure analysis is much high, FA engineers were often puzzled where to begin from. Two such cases were presented in this(More)
