In plain words: They compared older convolutional networks with newer vision transformers, each trained either on labeled images or on image-text pairs, at similar accuracy and computing cost. Despite matching scores, the models made different mistakes and behaved differently, so one accuracy number hides real differences.

Abstract · ConvNet vs Transformer, Supervised vs CLIP: Beyond ImageNet Accuracy

Modern computer vision offers a great variety of models to practitioners, and selecting a model from multiple options for specific applications can be challenging. Conventionally, competing model architectures and training protocols are compared by their classification accuracy on ImageNet. However, this single metric does not fully capture performance nuances critical for specialized tasks. In this work, we conduct an in-depth comparative analysis of model behaviors beyond ImageNet accuracy, for both ConvNet and Vision Transformer architectures, each across supervised and CLIP training paradigms. Although our selected models have similar ImageNet accuracies and compute requirements, we find that they differ in many other aspects: types of mistakes, output calibration, transferability, and feature invariance, among others. This diversity in model characteristics, not captured by traditional metrics, highlights the need for more nuanced analysis when choosing among different models.
