Feb 14
- Formalized the proposed design. Analyzing why a specific family of function are used, the speedup attained, the evaluation measurement.
Feb 7
- Studied LSH and explored different LSH families according to the distance measurement they use.
- Based on how LSH methods work, analysed how these LSH methods can be parallelized in distributed environment.
Jan 31
- Examined how the main class clustering algorithms can be parallelized, respectively.
- Explained spectral clustering from theoretical aspect, from graph cut viewpoint.
- Based on the understanding of main clustering algorithms, proposed optimizing method for spectral clustering to deal with large data set.
