WebNov 20, 2024 · Since a = math.sqrt (5) the weights are initialised with std = 1 / math.sqrt (3.0 * fan_in). For reference, LeCun initialisation would be 1 / math.sqrt (fan_in) and He initialisation uses math.sqrt (2 / fan_in). The bias initialisation in Linear.reset_parameters reveals another problem. Although biases are normally initialised with zeros (for ... WebSep 1, 2024 · In the works, devoted to MLP and CNNs, one chooses xavier/glorot or he initialization by default, as they can be shown to approximately preserve the magnitude in the forward and backward pass, as shown in these notes.
