假设在GNN中存在三个结点$x_1$,$x_2$,$x_3$,相应地,在RNN中有一个序列$(x_1,x_2,x_3)$。笔者认为,GNN与RNN的区别主要在于4点: GNN的基础理论是不动点理论,这就意味着GNN沿时间展开的长度是动态的,是根据收敛条件确定的,而RNN沿时间展开的长度就等于序列本身的长度。 GNN每次时间步的输入都是所有...
Now, we need to plug the value of \(x_V = \displaystyle -3\) into the quadratic function, so we get: \[y_V = f(x_V)\] \[ = \frac{1}{3}\cdot \left(-3\right)^2+2\cdot \left(-3\right)-3=\frac{1}{3}\cdot \left(-3\right)^2+2\cdot \left(-3\right)-3=9\cdo...
