  • An Evaluation of the Usefulness of Case-Based Explanation 

    Cunningham, Padraig; Doyle, Donal; Loughrey, John (Trinity College Dublin, Department of Computer Science, 2003)
    One of the perceived benefits of Case-Based Reasoning (CBR) is the potential to use retrieved cases to explain predictions. Surprisingly, this aspect of CBR has not been much researched. There has been some early work on ...
  • Overfitting in Wrapper-Based Feature Subset Selection: The Harder You Try the Worse it Gets 

    Cunningham, Padraig; Loughrey, John (Trinity College Dublin, Department of Computer Science, 2005-01-28)
    In Wrapper based feature selection, the more states that are visited during the search phase of the algorithm the greater the likelihood of finding a feature subset that has a high internal accuracy while generalizing ...
  • Using Early Stopping to Reduce Overfitting in Wrapper-Based Feature Weighting 

    Loughrey, John; Cunningham, Padraig (Trinity College Dublin, Department of Computer Science, 2005-05-18)
    It is acknowledged that overfitting can occur in feature selection using the wrapper method when there is a limited amount of training data available. It has also been shown that the severity of overfitting is related to ...
  • Using Early-Stopping to Avoid Overfitting in Wrapper-Based Feature Selection Employing Stochastic Search
