The first shows the Jacobian matrix of constraints and the norm of each Hessian matrix of constraints. There is one matrix for each phase. The first half of the plot can be used to verify if some constraints are redundant. It simply compares the rank of the Jacobian with the number of co...
Generally speaking,torch.autogradis an engine for computing vector-Jacobian product. It computes partial derivates while applying the chain rule. # Model with non-scalar output:# If a Tensor is non-scalar (more than 1 elements), we need to specify arguments for backward()# specify a gradient...
_forward_log_det_jacobian函数的输入变量为x,其函数需要返回的就是_forward函数的导数的log值,也就是log( _forward(x)导数 ),由于上面代码的_forward函数为tf.exp(x),因此_forward(x)的导数也为tf.exp(x),log( _forward(x)导数则为tf.log(tf.exp(x))=x,因此_forward_log_det_jacobian函数的输出已经...
