Week 4 (18 Jun - 22 Jun)
Monday
- Out for wedding
Tuesday
- Wrote working abstract
- Wrote summaries for related works section
- Read Anomaly Detection in Streaming Non-stationary Temporal Data
- Read Chapter 5 of Operations & Maintenance Best Practices Release 3.0
- Tested different features in LS-SVM; residuals are very low
Wednesday
- Meeting with Dr. Corliss, showed LS-SVM results
- Work on conference paper with graduate student
- LS-SVM Tuning
- Work on PPT for presentation
Thursday
- Practice presentation at GasDay Seminar
- Working REU lunch
- Knowledge and Information Discovery with Dr. Povinelli
- Project meeting with Dr. Povinelli and graduate student
Friday
- Recursive nonlinear autoregressive model with LS-SVM
- Clarification on building different models with different time horizons instead of recursive approach
- Coding nonlinear autoregressive model with LS-SVM with multiple time horizons
- Work on abstract
- Work on background
Week 5 (25 Jun - 29 Jun)
Monday
- Worked on slides for presentation on Thursday
- Tried to debug direct multiple time horizon least squares support vector machine nonlinear autoregressive model (LS-SVM NAR)
- Showed abstract to Dr. Povinelli, got feedback
- Resampled data to 1 minute and wrote several MATLAB scripts to automate the LS-SVM NAR process
- Came to the conclusion that LS-SVM NAR is not predicting well at all. Plotted values were erroneous and coincidentally showed promising results
