TruncNormalInit¶
- class mmengine.model.TruncNormalInit(mean=0, std=1, a=- 2, b=2, **kwargs)[source]¶
Initialize module parameters with the values drawn from the normal distribution \(\mathcal{N}(\text{mean}, \text{std}^2)\) with values outside \([a, b]\).
- Parameters
mean (float) – the mean of the normal distribution. Defaults to 0.
std (float) – the standard deviation of the normal distribution. Defaults to 1.
a (float) – The minimum cutoff value.
b (float) – The maximum cutoff value.
bias (float) – the value to fill the bias. Defaults to 0.
bias_prob (float, optional) – the probability for bias initialization. Defaults to None.
layer (str | list[str], optional) – the layer will be initialized. Defaults to None.
- Return type
