  • A Modified K-Nearest Neighbor Classifier to Deal with Unbalanced Classes 
    Al Sukker Akram; Al-Ani Ahmed; Atiya Amir (INSTICC - Institute for Systems and Technologies of Information, Control and Communication, 2009)
    We present in this paper a simple, yet valuable improvement to the traditional k-Nearest Neighbor (kNN) classifier. It aims at addressing the issue of unbalanced classes by maximizing the class-wise classification accuracy. ...
  • Pattern Classification using a Penalised Likelihood Method 
    Al-Ani Ahmed; Atiya Amir (Springer, 2010)
    Penalized likelihood is a well-known theoretically justified approach that has recently attracted attention by the machine learning society. The objective function of the Penalized likelihood consists of the log likelihood ...
  • A penalized likelihood based pattern classification algorithm 
    Atiya Amir; Al-Ani Ahmed (Elsevier, 2009)
    Penalized likelihood is a general approach whereby an objective function is defined, consisting of the log likelihood of the data minus some term penalizing non-smooth solutions. Subsequently, this objective function is ...
