 ### Model Description
 
-The ***ResNet50 v1.5*** model is a modified version of the [original ResNet50 v1 model](https://arxiv.org/abs/1512.03385).
+The **_ResNet50 v1.5_** model is a modified version of the [original ResNet50 v1 model](https://arxiv.org/abs/1512.03385).
 
 The difference between v1 and v1.5 is that, in the bottleneck blocks which requires
 downsampling, v1 has stride = 2 in the first 1x1 convolution, whereas v1.5 has stride = 2 in the 3x3 convolution.

 Note that the ResNet50 v1.5 model can be deployed for inference on the [NVIDIA Triton Inference Server](https://github.com/triton-inference-server/server) using TorchScript, ONNX Runtime or TensorRT as an execution backend.
