Fast stratification of geological cross-section from CPT results with missing data using multitask and modified Bayesian compressive sensing [PDF]

open access: yesCanadian geotechnical journal (Print), 2023
Because cone penetration test (CPT) is reasonably rapid, affordable and repeatable, it has been widely used in-situ for subsurface soil stratification and classification in geological and geotechnical engineering practice.
