Machine Learning Engineer definition

A machine learning engineer is someone who uses concepts in computer science and manipulates them to design, build and maintain a piece of software which is able to make decisions by itself, known as artificial intelligence. They do this by training the AI with a set of controlled images in order to train the model to correctly identify what is in the image when an image not in the controlled set of images is fed through the system.
