_How to set KBLOCK and STRIPES?_
KBLOCK should be smaller then the dimension of the dataset. Best fitting values for stripes are: $`1,2,5,14,41 (=((3^j)+1)/2)`$.
KBLOCK should be smaller then the dimension of the dataset. We check after KBLOCK dimensions whether we have exceeded $`\varepsilon^2`$ or not. Best fitting values for active dimesnions are $`0,1,2,3,4,5`$ which corresponds to $`1,2,5,14,41 (=((3^j)+1)/2)`$ stripes, (for more details see paper Section 3.1 "Determination of the Bounds")
In our experiments (see paper) we _always_ use the following setting:
- KBLOCK=4
- active dimensions=3, which are exactly 14 stripes (see paper Section 3.1 "Determination of the Bounds")
- active dimensions=3, which are exactly 14 stripes
For uniform data we suggest to use the following parameter settings:
- KBLOCK=16
