+Quantized ResNet
+================
+
+.. currentmodule:: torchvision.models.quantization
+
+The Quantized ResNet model is based on the `Deep Residual Learning for Image Recognition
+<https://arxiv.org/abs/1512.03385>`_ paper.
+
+
+Model builders
+--------------
+
+The following model builders can be used to instantiate a quantized ResNet
+model, with or without pre-trained weights. All the model builders internally
+rely on the ``torchvision.models.quantization.resnet.QuantizableResNet``
+base class. Please refer to the `source code
+<https://github.com/pytorch/vision/blob/main/torchvision/models/quantization/resnet.py>`_
+for more details about this class.
