Dr MD Masud Rana
Which machine learning algorithm outperformed the others in terms of performance, according to the study?
XGBoost outperformed the other models in terms of performance, showing the highest accuracy (97%), AUC (0.97), and strong precision (98%) and recall (98%) for both classes.
What were the performance metrics reported for XGBoost in spam email classification?
XGBoost achieved an accuracy of 97%, an AUC of 0.97, and demonstrated strong precision (98%) and recall (98%) for both the spam and ham classes.
How did KNN perform in comparison to other models in terms of accuracy and precision/recall for class 0?
KNN showed high accuracy (95%) and strong precision (94%) and recall (99%) for class 0, though it did not perform as well overall as XGBoost.
What were the key performance issues with the Decision Tree model?
The Decision Tree model had an accuracy of 92%, but it showed a performance drop for class 1 (ham), indicating that it was less robust compared to XGBoost and KNN.
What future research directions are suggested for improving spam email detection?
Future research will focus on applying advanced techniques such as deep learning and reinforcement learning to optimize spam email detection and tackle emerging email threats. |
