PyTorch Image Models (timm): The De-Facto Standard Vision Backbone Library

Created and maintains `timm`, providing 1,000+ pre-trained vision models (ResNet, ConvNeXt, ViT, Swin, EVA) with modular feature extractors, augmentations (Mixup, CutMix), and production export utilities.

Scope & limitations

Enormous model zoo requires periodic deprecation of older checkpoint architectures to keep maintenance manageable.

Context: PyTorch, ONNX, TorchScript, CoreML, ImageNet-1k/22k pre-trained weights.

ResNet Strikes Back: An Improved Training Procedure in PyTorch

Co-authored the NeurIPS 2021 benchmark study demonstrating that modern training recipes (BCE loss, RandAugment, AdamW) lift standard ResNet-50 accuracy from 76.5% to 80.4% without any architectural changes.

Scope & limitations

Heavy data augmentations significantly increase training epochs and compute overhead compared to vanilla SGD.

Context: ResNet-50, LamB/AdamW optimizers, repeated augmentations.
