Lifelong Sequential Learning

Project 2:

Particle Filtering Application with Mobile Behavior Lifelogs

• Board for discussion
• Description
• Overall introduction: Introduction (PDF)

• S/W Environment
• Matlab
• You can download and install Matlab under SNU campus licence: my.snu.ac.kr à Quick Menu à SW Download à '소프트웨어 목록' à [MathWorks] MATLAB / Simulink
• Tutorials: Matlab Primer by MathWorks, Week 2 materials of Machine Learning class (4190.428)
• If you have problems to get Matlab, you can use GNU Octave as an alternative
• Matlab toolboxes
• PMTK3

• Simple dataset(Readme, PersonA, PersonB, PersonC, PersonD, PersonE),
  Raw dataset(Readme, PersonA, PersonB, PersonC, PersonD, PersonE), Raw log sample (text files)
• For this project, 5 person’s mobilephone-based lifelogs are provided.
• Specification of columns is described in the link Readme above.
• Simple dataset is just only for Not-computer-friendly students. It’s NOT recommended. (scheduled to be uploaded on Nov. 7)
• You may do any kinds of preprocessing. You may share them in the board.
• We’ve found that PersonA’s companionscell is missing in PersonA_raw_dataset. Here is PersonA_companionscell.

• Test dataset (full version) (same spec. with raw dataset, PersonA, PersonB, PersonC, PersonE)
  Test dataset (smartphone-sensor-only) (Readme, PersonA, PersonB, PersonC, PersonE)
• Smartphone-sensor-only test dataset has been uploaded on Nov. 19. (For detail, please read readme)
• Additionally, overall test dataset including diary information will be opened on Nov. 21 ~ 22. Some instances can be removed in the process of attaching diary information.
• Person D's test dataset will be NOT available. To test his model, separate 3/4 early part for training set, 1/4 latter part for test set.

• Practices
• Student Dave’s Tutorial (Oct, 29)
• Practice 2 (Oct, 31)
• Practice 3 (Nov, 5) / HMM_PF / PF for Hierarchical Variable-Duration HMM
• The typo-fixed ppt is uploaded.
• Scr_PF_practice3.m file and HMM_PF codes are uploaded. (Nov. 7) The previous zip files included the old version.
• Some bugs were found in scr_PF_practice3.m file. Thank 박준현 for reporting. The fixed one are uploaded. For detail, see the board.
• For your reference, ‘PF for Hiearchical Variable-Duration HMM’ codes are uploaded. (Nov. 15). Good luck!

• Announcement for Project Meeting has posted on the bulletin board.
• Project meeting schedule has posted on the bulletin board.
• New Late Policy
• Even if you already submitted, you may resubmit your work by Dec. 15^th. The last submission will be evaluated as your final score.
• (updated) -5 % per 1 day
• Maximum 12 days

• Poster template / Poster example
