Question

How exactly are datasets larger than 250 MB reduced during benchmarking? What sampling strategy is used?

Hello ST Community,

 

I noticed that when using the benchmarking tool, datasets larger than 250 MB are 

automatically reduced using a "representative sampling strategy" that preserves 

the diversity and distribution of the original data.

 

I would like to understand more details about this process:

 

1. What specific sampling algorithm/strategy is used? (e.g., random sampling, 

   stratified sampling, systematic sampling, etc.)

 

2. How is the target size of 250 MB determined? Is this configurable?

 

3. How does the tool ensure that the sampled dataset preserves:

   - The original data distribution?

   - The diversity of data samples?

   - Edge cases and boundary values?

 

4. After optimization, when we validate the model on the full dataset, what 

   performance differences should we typically expect between the sampled 

   dataset and the full dataset?

 

5. Is there any documentation that describes this sampling mechanism in detail?

 

Any information or pointers to relevant documentation would be greatly appreciated.

 

Thank you!
