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.
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.

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.
Heavy data augmentations significantly increase training epochs and compute overhead compared to vanilla SGD.
Context: ResNet-50, LamB/AdamW optimizers, repeated augmentations.
