• preprocessing
  • Using as few pixels from the video to do prediction (which channels? Which part of the image? e.g. using gradient to find if phone is only partly on, and then take the part where it is on the best)
• noise reduction
  • making an as clean as possible PPG graph
    • e.g. w/ kalman filters
• feature engineering
  • finding human-understandable features from the PPG that can be used in knowledge based methods
    • E.g. with FFT feature engineering, then feature selection, then human explainability
• black-box prediction: compute-heavy
  • Create best possible black-box prediction method
    • e.g. 1d resnet
• black-box prediction: compute-light
  • Create best possible black-box prediction method that can be run on mobile
    • E.g. mobilenet / squeezenet
