Instance norm has the effect of making the output invariant to mean and variance of each feature channel of the input. This is the same idea as contrast normalization.

Why do transformers use layer norm instead of batch norm?

Though it makes a valid neural network, there's no practical use for it. Batch normalization noise is either helping the learning process (in this case it's preferable) or hurting it (in this case it's better to omit it). In both cases, leaving the network with one type of normalization is likely to improve the performance.

Nettet5. apr. 2024 · 🐛 Describe the bug. When converting PyTorch model to .onnx it assumes that batchnorm layers are in training mode if track_running_stats=False even though layers clearly have training attribute set to False.
