Unofficial implementation of the EmotionROI essay and extended applications

ℹ The pretrained weights can be found here :)

Reproduction the FCNEL model in essay WHERE DO EMOTIONS COME FROM? PREDICTING THE EMOTION STIMULI MAP, and extended applications.

The results reported in the EmotionROI/FCNEL essay:

Reproduce FCNEL for ROI prediction

⚠ Can NOT reproduce essay results exactly, here're the implementation differences:

• The essay uses FCN-32s + AlexNet, we use FCN-8s + ResNet50
• The essay uses lr=1e-8 to refine 20 epochs, which is two small and doesn't have any effect in our setting, we instead use lr=1e-2 to train 100 epochs with CosineAnnealingLR
• The essay might use the default Bilinear for output upsacling, we instead use Nearest-Exact to simulate FCN-32s resolution

Modifyied EmoFCNEL for ROI prediction with emotion condition

ℹ Predict ROI with any emotion label (except for sadness) results into nearly the same output...
ℹ The ROI annotations are probably NOT related to certain emotion, but only indicates human attention focus

Predict emotion directly from ROI annotation

⚠ Mission impossible :(
