Как предсказать эмоции по лицевым ориентирам в Swift

Question

Я могу получить данные о ориентирах лица из VNFaceObservationв этой функции handleFaceDetectionObservations(observations: [VNFaceObservation])как это,

      private func handleFaceDetectionObservations(observations: [VNFaceObservation]) {
        for observation in observations {
            
            //FACE LANDMARKS
            if let landmarks = observation.landmarks {
                
                if let leftEye = landmarks.leftEye {
                    self.handleLandmark(leftEye, faceBoundingBox: faceRectConverted)
                }
                if let leftEyebrow = landmarks.leftEyebrow {
                    self.handleLandmark(leftEyebrow, faceBoundingBox: faceRectConverted)
                }
                if let rightEye = landmarks.rightEye {
                    self.handleLandmark(rightEye, faceBoundingBox: faceRectConverted)
                }
                if let rightEyebrow = landmarks.rightEyebrow {
                    self.handleLandmark(rightEyebrow, faceBoundingBox: faceRectConverted)
                }

                if let nose = landmarks.nose {
                    self.handleLandmark(nose, faceBoundingBox: faceRectConverted)
                }

                if let outerLips = landmarks.outerLips {
                    self.handleLandmark(outerLips, faceBoundingBox: faceRectConverted)
                }
                if let innerLips = landmarks.innerLips {
                    self.handleLandmark(innerLips, faceBoundingBox: faceRectConverted)
                }
            }
        }
    }

Итак, есть ли способ предсказать эмоции лица (например, улыбку, гнев) на основе вышеуказанных ориентиров?
