Results vary between hosts when there is data disparity between them.

Issue description

• issue description: I have tried using an SQLi CNN model, but with different data between hosts (different in number or different in number of samples) they all produce different results between hosts. When I run mnist example with data is imbalanced between host it's run perfectly. I made no adjustments except for the python model file and data. Has anyone encountered this and can give me some advice?
• occurrence - consistent or rare: consistent
• commands used for starting containers: same at example
• docker logs [APLS, SPIRE, SN, SL, SWCI]:

• Host 1, ML logs:
  

• Host 2, ML logs:
  

• Other logs is same at I run example mnist

• Python file model I use:

Hi @VuDuc09, the final Swarm Learning model will be same across the Hosts. If you have applied different dataset across the Hosts then the inference results could be different. Let us know if you still have any concerns.

When i test with mnist dataset example, I split a dataset with a ratio between 2 host and I have a same result. And besides thât in two case, mnist dataset with example model and my dataset with my model have a same test data between two host, just a train data is different.

Hi @VuDuc09, we could not completely understand the use-case that you mentioned. As this is not exactly an issue with Swarm Learning core components, we can continue this in the discussion.
