Some confusion about config.py #6
Comments
It means that if you want to train in single scale rather than multi-scale, what scale of the input image you want to set. |
@scnuhealthy Thank you for your reply! But I'm sorry I don't quite get your idea. |
Thanks for your question. target_dist is to control the resolution of input when training in single scale.(Training in a larger resolution usually results in better result.) If you close data augmentation and want to train in the original resolution of the input, just set target_dist=1.0. |
Thank you for your reply. But just to make it clear (you know, students' habits 😂 )
|
@scnuhealthy BTW, is there any possibility we could talk on Wechat? |
For two questions: 2 Multi-scale testing will achieve better result. For example, if you train in scale S, test in 0.8S, 1.0S and 1.2*S, and then ensemble the three results, the performance will be better. (A common way for improving mAP in COCO dataset.) |

Keeping the ratio throught padding is better during inference and I also use this strategy when training. |
First of all, thank you so much for providing such great code! I just don't understand some parameters you use in your code, especially in your data augmentation part.
Specificly, what does the
TransformationParams.target_dist
do, which has been set to a constant equal 0.8. I mean you have done random scale already, why do you still want to add a constant factor here?Again thank you for your great code! I have learned a lot of staff from it.
