mxnet.initializer.MSRAPrelu¶

class mxnet.initializer.MSRAPrelu(factor_type='avg', slope=0.25)[source]¶

Initialize the weight according to a MSRA paper.

This initializer implements Delving Deep into Rectifiers: Surpassing Human-Level Performance on ImageNet Classification, available at https://arxiv.org/abs/1502.01852.

This initializer is proposed for initialization related to ReLu activation, it maked some changes on top of Xavier method.

Parameters

factor_type (str, optional) – Can be 'avg', 'in', or 'out'.
slope (float, optional) – initial slope of any PReLU (or similar) nonlinearities.

__init__(factor_type='avg', slope=0.25)[source]¶: Initialize self. See help(type(self)) for accurate signature.

Methods

`__init__`([factor_type, slope])	Initialize self.
`dumps`()	Saves the initializer to string
`set_verbosity`([verbose, print_func])	Switch on/off verbose mode
