Max-Margin Multi-Label classifier takes label correlation. The performance is better than the simplistic one-versus- all SVM classifier. But still not as good as the Naive Bayes classifier. Because SVM is not a probabilistic model

Debnath ICT 6522: Data Warehousing and Mining 10th August, 2016 First, not all students are active on Twitter. Second, consideration on only negative aspect but not positive on learning experiences Third, identified the prominent themes with relatively large number of tweets in the data. Fourth, the qualitative analysis reveals that there are correlations among the themes. Limitations

Debnath ICT 6522: Data Warehousing and Mining 10th August, 2016 First, The “manipulation” of personal image online may need to be taken into considerations in future work. Second, Future work can compare both the good and bad things to investigate the tradeoffs with which students struggle. Third, Future work can be done to design more sophisticated algorithms in order to reveal the hidden information in the “long tail”. Fourth, Future work could specifically address the correlations among these student problems. Future Work

Debnath ICT 6522: Data Warehousing and Mining 10th August, 2016 Through a qualitative content analysis, we found that engineering students are largely struggling with the heavy study load, and are not able to manage it successfully. Heavy study load leads to many consequences including lack of social engagement, sleep problems, and other psychological and physical health problems. This detector can be applied as a monitoring mechanism to identify at-risk students. Conclusion
