Purpose
Implement a good user aggregation and classification.
or to assess the interrelation patterns between user profiles.
Data
i. daily temperature and load profiles sampled at hourly for one year.
ii. 2201 customers
iii.
Methodology
1. correlation matrix R of all pairs of users;
2. transform the correlation matrix R into a distance matrix D;
?? why?因为相似度和距离是反的, 相似度越大,距离越近, 显然以距离作为边权重更合适.
3. network construction;
each user is a node; the weighted connections are established between all of them; weight eij = Dij.
4. extract the MST network
5. community detection
Newman.
