One who knows Machine Learning is called ...

The short answer: A Machine Learning Engineer

Brief explanation:

• 🗡️ First, we have a Software Engineer: one who writes code to solve problems.
• 🗡️ Also, we have a Data Scientist: one who collects, analyzes, and interprets extremely large amount of data.
• ⚔️ And now, we have a Machine Learning Engineer: one who does the both roles above. They write code that analyzes a large dataset to solve a specific problem.

looking forward to being a Full stack Machine Learning Engineer.😏
