Hello, it looks like that step1 is not right if I understand it correctly.
In step1, for the node 4, it gets (1, 14) not (1, 4).

node index after comma are all neighbor nodes' indices, thus 1 is excluded.

I am sorry, I mean if some nodes are not labeled correctly.

you are right, I have fix the problem, thanks

请问为什么后话部分说“单层感知机不是单射函数”呀?单层感知机由矩阵乘法、激活函数组成,矩阵乘法是单调函数,激活函数如果也是单调的(比如tanh、sigmoid),那么由于单调函数一定是单射函数,单层感知机就是单设函数啊?

您好,矩阵乘法不一定是单射的,矩阵乘法单射的充要条件是矩阵为列满秩矩阵。
