自定义neural network class先需要 -继承nn.module, -然后实现__init__函数定义网络层 -实现forward函数实现对输入数据的操作,在使用时,直接将数据传入model,model会自动执行forward函数,不要直接执行model.forward() class NeuralNetwork(nn.Module): def __init__(self): super().__init__() self.layer = ...
接下来,我们需要使用PyTorch训练我们的倦极神经网络。这里我们以二分类问题为例,使用交叉熵损失函数和随机梯度下降优化器进行训练。 实例化模型对象: model = FatigueNeuralNetwork(input_size, hidden_size, output_size) 其中,input_size为输入层的大小,hidden_size为隐藏层的大小,output_size为输出层的大小。 定义...
