Kumita ← Open visual lesson

Keep the strongest response

The code behind the picture

Follow the lesson’s implementation, one code cell at a time.

Choose a language and read the cells in order. These are small teaching examples; the visual lesson runs separately.

Follow the calculation

Same inputs · Same operation · Same result

3 teaching cells · Python standard library · Read-only

1. Prepare the inputs
One 2 × 2 region of the watermelon's feature map: four responses from the lesson.
In [ ]:
```
import json

block = [[6, 16], [0, 11]]
```
2. Keep the local maximum
A 2 × 2 pooling window contributes one value, its largest. Moving the maximum within this window preserves that value.
In [ ]:
```
result = max(value for row in block for value in row)
```
3. Inspect the result
Print the result as JSON so both languages use the same output format.
In [ ]:
```
print(json.dumps(result))
```

Expected result

Running the three cells in order produces this result in either language.
