| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary This paper explores explainability techniques for binary deep neural architectures in emotion classification through video analysis. The authors investigate the optimization of input features to binary classifiers for emotion recognition using an improved version of Integrated Gradients. They employ an innovative explainable AI algorithm to understand facial landmarks movements during emotional feeling, optimizing the number and position of landmarks used as input features. This approach improves the accuracy of deep learning-based emotion classifiers while reducing noisy landmark impact. To test its effectiveness, the authors consider a set of deep binary models for emotion classification trained with complete facial landmarks, which are progressively reduced based on optimization procedures. The results demonstrate the robustness of the proposed approach in understanding relevant facial points for different emotions, improving classification accuracy, and diminishing computational cost. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary This paper is about making artificial intelligence (AI) models explainable, so we can understand how they make decisions. In this case, the AI is trained to recognize emotions from videos by looking at people’s faces. The authors developed a new way to analyze facial landmarks, like eye and eyebrow movements, that help tell us what emotion someone is feeling. This method helps improve the accuracy of the AI models while reducing errors caused by noisy or irrelevant data. The results show that this approach works well and can be used for other tasks too. |
