About Lasso #2

zyy341 commented 2 years ago

Hi, I'm interested in the Lasso part, but I didn't find the code for the Lasso part. Can you tell me where the code corresponding to the LASSO part is? Thank you！

Hi, thanks for your question.

To run Lasso, you can simply run test_l1Fourier_lifted.py with --lifting 1. That will use sparsity in the Fourier (beamspace) domain as a prior. You can check this on lines 144-152 in that file for the exact implementation.

Let me know if there's more questions.
