Non-negative matrix factorization (NMF) is an efficient dimension reduction method and plays an important role in many pattern recognition and computer vision tasks. However, conventional NMF methods are not robust since the objective functions are sensitive to outliers and do not consider the geometric structure in datasets. In this paper, we proposed a(More)
Non-negative matrix factorization (NMF) is a powerful dimension reduction method and has been widely used in many pattern recognition and computer vision problems. However, conventional NMF methods are neither robust enough as their loss functions are sensitive to outliers, nor discriminative because they completely ignore labels in a dataset. In this(More)
The Musca domestica antifungal peptide-1A (MAF-1A peptide) from housefly larvae was synthesized by solid-phase synthesis technique, and antiviral, antioxidant, and antifungal properties were evaluated in this study. Present results indicated that it could significantly inhibit the infection of influenza virus H1N1, Autographa californica multicapsid(More)
In this work, physical layer impairments and their impacts on transparent optical networks is studied. Among the impairments we mainly focused on in band crosstalk and try to incorporate its effect in the DWDM process. BER due to component crosstalk in a WDM receiver has been studied and computed results are shown by simulation as a function of number of(More)
Non-negative matrix factorization (NMF) reconstructs the original samples in a lower dimensional space and has been widely used in pattern recognition and data mining because it usually yields sparse representation. Since NMF leads to unsatisfactory reconstruction for the datasets that contain translations of large magnitude, it is required to develop(More)
