📌 This is an official PyTorch implementation of [ICCV 2023] - TinyCLIP: CLIP Distillation via Affinity Mimicking and Weight Inheritance
TinyCLIP is a novel cross-modal distillation method for large-scale language-image pre-trained models. The method introduces two core techniques: affinity mimicking and weight inheritance. This work unleashes the capacity of small CLIP models, fully leveraging large-scale models as well as pre-training data and striking the best trade-off between speed and accuracy.
- TinyCLIP ViT-45M/32 uses only half parameters of ViT-B/32 to achieves comparable zero-shot performance.
- TinyCLIP ResNet-19M reduces the parameters by 50% while getting
$2\times$ inference speedup, and obtains 56.4% accuracy on ImageNet.
- Dec.2023 TinyCLIP models have been integrated into 🤗Hugging Face Model Hub.
- Oct.2023 Training code is released.
- Sep.2023 This is preliminary released code, including inference code and checkpoints.
