What this tutorial covers
Understand the role and placement of pooling layers in the visual model graph.



Step-by-step workflow
1Open the module
Locate the pooling layer inside the model graph. Confirm that the visible page really matches the tutorial topic before changing any settings.
2Configure the input
Prepare and check pool size, stride and the surrounding layer connections.
3Run and watch the status
Inspect how the pooling layer affects later feature-map dimensions. Watch the visible status, plot or log area while the workflow is running.
4Inspect the result
Pay special attention to a CNN graph containing pooling blocks together with training context.
5Verify and iterate
Aggressive pooling can shrink spatial resolution too quickly, so read it together with the resulting accuracy. Change one meaningful parameter and rerun so you can verify whether the output changes in the expected direction.
How to read the result
- The main output of this workflow is a CNN graph containing pooling blocks together with training context.
- Read the result together with the exact inputs used for the run; a screenshot alone rarely tells the whole story.
- Aggressive pooling can shrink spatial resolution too quickly, so read it together with the resulting accuracy.
Troubleshooting & practical tips
- If nothing changes, first confirm that the correct module is open.
- If the output looks unrealistic, check units, field mapping and input scale first.
- For comparisons, change one key parameter at a time whenever possible.
