单项选择题

假设你正在训练一个神经网络。其中一个神经元具有输入向量 [12, 35, -80, -0.4, 21]、权重 [0.1, -0.6, 0.2, -0.01, 2]、偏置 0.45 和 ReLu 激活函数。以下哪一个是 ReLu 激活函数的输出值？ Suppose you are training a neural network. One of the neurons has an input vector [12, 35, -80, -0.4, 21], weights [0.1, -0.6, 0.2, -0.01, 2], bias 0.45, and a ReLu activation function. Which value is the output of the ReLu activation function?
