内容記述 | In this paper, the effectiveness of the multilayer perceptron model for detecting credit card fraud records was examined by using real data. Since the original data set had an imbalance between normal and abnormal data, a shaping process was applied. Next, we conducted a preliminary experiment to determine the model structure to be used for the detection of credit card fraud records. The model was trained by inputting well-formed data to the model structure determined by pre-liminary experiments. Each model trained with differently processed data sets were validated if the models can discriminate between abnormal and normal transactions with a validation data set. Four evaluation indices were used to evaluate each model that discriminated between abnormal and normal. For the purpose of this study, the maximum value of recall, which indicates the percentage of fraudulent transactions that were actually judged to be fraudulent, was approximately 98 % . For practical use, the value of recall should be close to 100 % , so further improvement is needed. |
