how to interpret the output of the ganger_lasso about causal-learn

[kunwuz]

Hi, maybe something as follows could be helpful:

reshaped_coeff = np.zeros((T, N, N))
for t in range(T):
    block = coeff[:, N*t:N*(t+1)]
    reshaped_coeff[t] = block

Thank you for the prompt reply.

I have one more thing to clarify. In the implementation, it says:

The ij-th entry in A_k represents the causal influence from the j-th variable to the i-th variable.

Should I expect the same for the reshaped matrix?

Thank you!

it should be guaranteed if you use the code provided by kunwz. You can also check whether the t-th NxN matrix is the same as coeff[:, Nt:N(t+1)].
