Grouping features in big dimensionality
Published 2016“…Based on the observation of the growing trend of big dimensionality on modern databases, existing approaches that require the calculations of pairwise feature correlations in their algorithmic designs have scored miserably, since computing the full correlation/covariance matrix (i.e., square of dimensionality in size, where million features would translate to trillion correlation computations) can become computationally very impractical. …”
