Scale-dependent wavelet-based regularization scheme for geophysical 1D inversion.
This flexible inversion scheme allows to easily obtain blocky, smooth and intermediate inversion models. Different inversion models are obtained by simply changing the wavelet basis. - db1: blocky inversion models - db2-db4: sharper inversion models - db5+: smoother inversion models
Daubechies (db) wavelets are ideal (see Deleersnyder et al, 2021), however, other wavelets can also be used. Simply run pywt.wavelist() to list the available options. The shape of the wavelet basis function (e.g., look here) is an indication of the type of minimum-structure the regularization method will promote.
- Fits within the modular SimPEG framework (see SimPEG website) (see examples)
- Fits within your own inversion codes (see examples with empymod)
