1. Relative Attributes

  • Extract emotion related features by OpenSMILE toolkit. (384-dim)
  • Train Ranking function (Linear) based on the RA.
  • Normalize the intensity values to the range 0 ~ 1.

2. Intensity Distribution

angry happy sad surprise

3. Intensity Embedding

  • Map the real number to high dimensional embedding: (effective) $$Inty*W$$

  • Combine the neutral and emotional embeddings: (not so effective) $$Neu*(1-Inty)+Emo*Inty$$

  • Combine the neutral and emotional embeddings: (To be done) $$Neu.detach()(1-Inty)+EmoInty$$
