[vip-help] Brain Tumor Detection Code suggestion for UNet

[Chen, Alain]

Hi Chingwo,

Here are some comments Yue and I have for you:
1.Are you trying to output a 4 or 5 value vector? We are seeing conflicting information in the comments in your code
2. Unets are usually used for segmentation tasks and not for bounding box detection. Is there a reason why you chose Unet for this? (we discussed this after class last Tuesday)

Thanks,

Good evening,

We have trouble getting a good result using UNet for bounding box detection. Could you take a look at our code and give us some suggestions on what could be potential mistakes? The code for UNet architecture is in the UNetBackbone.py and UNetForBoundingboxDetection.py files in the VIP-IPA/TumorDetection_F23 - VIP Gogs (purdue.edu)<https://buddy-boy4.ecn.purdue.edu:3000/VIP-IPA/TumorDetection_F23> repository.

Best,
Chingwo Cheung
