    • Limited random walk algorithm for big graph data clustering 

      Zhang, Honglei; Raitoharju, Jenni; Kiranyaz, Serkan; Gabbouj, Moncef ( SpringerOpen , 2016 , Article)
      Graph clustering is an important technique to understand the relationships between the vertices in a big graph. In this paper, we propose a novel random-walk-based graph clustering method. The proposed method restricts the ...

    • Training Radial Basis Function Neural Networks for Classification via Class-Specific Clustering 

      Raitoharju, Jenni; Kiranyaz, Serkan; Gabbouj, Moncef ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)
      In training radial basis function neural networks (RBFNNs), the locations of Gaussian neurons are commonly determined by clustering. Training inputs can be clustered on a fully unsupervised manner (input clustering), or ...
