near-far-ratio (NFR = EJE,, i = 2,3,4,5) with the signal-to-noiseratio (SNR) of user 1 being futed at 8dB. It can be seen from Fig. 1 that the TSTCNN detector outperforms the HNN detector over the NFR range. When the NFR is low, the TCNN detector has poor performance. As the NFR increases, the performance of both the TCNN detector and the TSTCNN detector approach that of the optimum detector cl...

Customer classification is an area of utmost interest for all businesses. For any organization retaining customer is more important than making new customers. In this paper, a simple idea based on Hopfield Neural Network (HNN) is proposed for multiclass classification of customer loyalty. Initially, transformation and k-medoid clustering algorithm preprocesses the training example dataset. Then...

Automatic pathological pulmonary lobe segmentation(PPLS) enables regional analyses of lung disease, a clinically important capability. Due to often incomplete lobe boundaries, PPLS is difficult even for experts, and most prior art requires inference from contextual information. To address this, we propose a novel PPLS method that couples deep learning with the random walker (RW) algorithm. We f...

We show that the commensurator of any quasiconvex abelian subgroup in a biautomatic group is small, sense it has finite image abstract subgroup. Using this criterion we exhibit groups are CAT(0) but not biautomatic. These also resolve number other questions concerning groups.
