 ## Inference
 
+Channels last is a memory layout format that is more friendly to Intel Architecture. It is recommended for users to utilize this memory layout format for computer vision workloads. It is as simple as invoking `to(memory_format=torch.channels_last)` function against the model object and input data.
+
+Moreover, `optimize` function of Intel® Extension for PyTorch\* applies optimizations to the model, and could bring performance boosts. For both computer vision workloads and NLP workloads, it is recommended to apply the `optimize` function against the model object.

 #### Calibration
 
+For calibrating a model with INT8 data type, code changes are highlighted in the code snippet below.
+
+Please follow the steps below:
+
+1. Utilize `torch.fx.experimental.optimization.fuse` function to perform op folding for better performance.
+2. Import `intel_extension_for_pytorch` as `ipex`.
+3. Instantiate a config object with `ipex.quantization.QuantConf` function to save configuration data during calibration.
+4. Iterate through calibration dataset under `ipex.quantization.calibrate` scope to perform the calibration.
+5. Save the calibration data into a `json` file.
+6. Invoke `ipex.quantization.convert` function to apply the calibration configure object to the fp32 model object to get an INT8 model.
+7. Save the INT8 model into a `pt` file.

 ## C++
 
 To work with libtorch, C++ library of PyTorch, Intel® Extension for PyTorch\* provides its C++ dynamic library as well. The C++ library is supposed to handle inference workload only, such as service deployment. For regular development, please use Python interface. Comparing to usage of libtorch, no specific code changes are required, except for converting input data into channels last data format. Compilation follows the recommended methodology with CMake. Detailed instructions can be found in [PyTorch tutorial](https://pytorch.org/tutorials/advanced/cpp_export.html#depending-on-libtorch-and-building-the-application).
