Deep Supervision with Intermediate Concepts

Area of Science:

• Computer Vision
• Machine Learning
• Artificial Intelligence

Background:

• Current scene interpretation methods often use end-to-end black-box Convolutional Neural Networks (CNNs).
• Perceptual organization research highlights the importance of intermediate representations for improved generalization in vision tasks.
• Prior domain structure is crucial for enhancing the robustness and interpretability of neural network models.

Purpose of the Study:

• To explore injecting prior domain structure into neural network training via deep supervision.
