Finding the Best Embedding Model for Image Classification: New Benchmark Results

Voxel51's research highlights the significance of selecting the appropriate embedding model for image classification tasks, revealing that DINOv2-ViT-B14 surpasses other models like ResNet and CLIP in accuracy across various datasets. Their study evaluated these models using three natural domain datasets comprising over 6 million images and 10,000+ classes, demonstrating DINOv2's superior capability to learn discriminative features with a self-supervised training approach. The study shows that while larger models offer richer representations, they require more computational resources, and the choice of model should depend on the specific requirements and constraints of the task, such as computational efficiency, accuracy, and the complexity of the classification task. Voxel51 recommends DINOv2 for fine-grained tasks and CLIP for general-purpose classification, considering resource constraints, while ResNet-18 remains a viable option for edge deployments due to its efficiency. The research emphasizes the importance of systematic benchmarking in selecting embedding models, and Voxel51 plans to expand their evaluations to include domain-specific datasets and noisy label scenarios.
