I am Jaired Collins, a student at Missouri Southern State University in Joplin, MO, currently majoring in computational mathematics. Outside of academia, I enjoy cycling, weights, table tennis, tennis, and cooking.

Week 1 (29 May - 1 Jun)

Tuesday

  • Initial meeting to get introduced into the program.
  • Lunch meeting with mentors.
  • Obtained MU and MSCS account logins and ID card
  • Paperwork

Wednesday

  • Met with Dr. Corliss to get acquainted with the GasDay lab and receive a key.
  • Met with Dr. Povinelli and another student to set up initial parameters of the project.
  • Literature review.

Thursday

  • More literature review
  • Seminar with GasDay
  • Meeting with Dr. Povinelli and student to establish a weekly plan and talk about the project.

Friday

  • Literature review
  • Planned for a presentation at a GasDay Seminar on the 21st of June
  • Data cleaning


Week 2 (4 Jun - 8 Jun)

Monday

  • Meeting with Dr. Corliss
  • Meeting with Dr. Povinelli and Colin
  • Literature search
  • Cleaned up more data

Tuesday

  • Meeting with Dr. Corliss
  • Data cleaning with bash and Matlab
  • Played around with data and SVMs in MatLab
  • Meeting with research consultant
  • Literature review

Wednesday

  • Cross validation with k-Fold

  • REU working lunch meeting, bad presentation

Friday

  • Meeting with Dr. Corliss
  • Creation of ShareLaTeX project
  • Converted temporal pressure data into nonuniform time series data
  • Tried resampling time series data into uniform data


Week 3 (11 Jun - 15 Jun)

Monday

  • Meeting with Dr. Corliss
  • Meeting with Dr. Povinelli
  • Resampled nonuniform data
  • Forecasting with ARIMA
  • Left computer running to finish ARIMA models

Tuesday

  • Examined and saved ARIMA models
  • Dissimilarity-based approach to prediction, where correlation coefficients between sensors are used as features
  • SVM and k-fold cross validation at k = 5, 10, and 20

Wednesday

  • Meeting with Dr. Corliss to elucidate LS-SVM for regression
  • Coding LS-SVM
  • RCR lunch meeting

Thursday

  • Meeting with Dr. Corliss, further explained LS-SVM
  • GasDay seminar
  • Coding of LS-SVM for regression
  • Meeting with Dr. Povinelli
  • Called contact to clarify threshold values

Friday

  • Out for wedding


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

Tuesday

  • Meeting with Dr. Corliss
  • Read more into SVMs and SVRs to help the LS-SVM NAR algorithm
  • Implementation of radial basis function kernel for LS-SVM NAR
