I would like to get my foot into the specialized areas like machine learning and artificial intelligence without having a related master's degree. What is the best way to get this opportunity as I'm searching for a new job? Is climbing across the ladder (transitioning to a different department) while working within a company the only way to gain the opportunity? Please feel free to suggest other tips on technically upskilling in special domains such as ML or AI where master's degree or PhD is most often required. Thank you.
