The Art of Hybrid Architectures
- The article explores building AI models that combine the strengths of different architectures to achieve expert-like visual recognition.
- The journey involves transitioning from traditional CNNs to hybrid architectures integrating CNNs, Transformers, and morphological feature extractors.
- Key phases include initial experimentation with EfficientNetV2-M and Multi-Head Attention, leading to F1 scores improvement through Focal Loss and ConvNextV2-Base integration.
- The final step focuses on creating a truly collaborative hybrid architecture where CNNs, Transformers, and morphological extractors work together effectively.
- The hybrid model excels at recognizing subtle structural features of breeds, achieving an F1 score of 88.70% through a balanced feature understanding.
- Strengths and limitations of CNNs and Transformers are highlighted, along with how they complement each other in visual recognition tasks.
- The technical implementation includes the MultiHeadAttention mechanism and the strategic selection of ConvNextV2 as the backbone.
- The article showcases how hybrid architectures outperform individual models, demonstrating improved confidence scores and reasoning abilities.
- Heatmap analyses reveal the evolution of model reasoning from local feature focus to structured morphological understanding, enhancing accuracy and reliability.
- Overall, the article emphasizes the significance of integrating diverse architectural elements to enhance AI visual systems' capabilities for complex recognition tasks.
- Through PawMatchAI development, valuable insights were gained on AI vision systems, feature recognition, and the importance of hybrid model design.
