ML/IA certifications

Which ML/IA certifications are more practical in a ML/IA career, since the filed and tools are ever changing and continuous education is necessary?

Having a PhD in Data Clustering does not turn me in a skilled professional in the most MLOps and other techniques in ML/IA nowdays. Also every professional is exposed to different kind of problems during a career and most practical problems don’t need “rocket science”, and this leads to a lack of experience in some particular niches.

Kaggle and other contests can be used to practice, but most of them don’t fit in the real problems of other niches. Also considering the limited time to use for both work and study ML/IA, which certification are sought as most valued by the industry?
