In the project "lung_nodule_ct_detection", how should I determine the size of the nodule?

[dqy818]

Each nodule has three dimensions: length, width, and height. In the LUNA16_datasplit JSON file, I noticed that the nodule sizes are the same across the three dimensions, but in reality, they are different. Which dimension should I use as the size for training data—the maximum, or the minimum of the three dimensions?
