Pre-trained models:

The models on Aff-Wild can be downloaded from here.

Description:

The above link contains 3 folders named: "affwildnet-vggface-gru" , "affwildnet-resnet-gru" and "vggface".

The "vggface" folder contains two subfolders with 2 different models: both models are CNN networks based on VGG-FACE (with 3 fully connected layers with: i) 4096, 2000, 2 and ii) 4096, 4096, 2 units, respectively).

The "affwildnet-vggface-gru" folder contains the AffWildNet architecture (with no landmarks) as described in the paper entitled: "Deep Affect Prediction in-the-wild: Aff-Wild Database and Challenge, Deep Architectures, and Beyond".

The "affwildnet-resnet-gru" folder contains the AffWildNet architecture (with no landmarks and no fully connected layer; a Resnet-50 followed by a GRU network) as described in the paper entitled: "Deep Affect Prediction in-the-wild: Aff-Wild Database and Challenge, Deep Architectures, and Beyond".

Inside each of those folders, one can find the architectures of the networks, implemented in the Tensorflow environment and a readme explaining how to build/use them. An evaluation file is also uploaded with detailed explanation inside.

The Aff-Wild database can be downloaded from here. Specific details about the database and related stuff can be read in the Challenge's site.

Prerequisites:

  • The code works with Tensorflow 1.8
  • slim is also needed (it is incorporated within Tensorflow)
