Detecting Ghostwriters in High Schools
Table 2: Results obtained on Ttest
['Method', 'Accuracy', 'FAR', 'CR']
Methods were trained and validated on Ttrain and Tval. For Burrows, we found k=4 to give the best results, while the parameters C=10,γ=103 were found optimal for the RBF kernel SVM. The optimal combination strategy Cs was found to be exponentially decaying weights ( Furthermore, δ=0.57 was found to be optimal. As it can be seen, our method clearly outperforms the baselines, on all metrics.
