At the present scenario, organisations are hiring machine learning professionals to build applications with the help of machine learning techniques. The impact of this emerging technology is globally concerned. In this article, we list down 10 frequently asked questions to prepare for machine learning interviews in 2019. In Supervised machine learning technique, the machine is trained by using labelled data. Then a new dataset is fed into the learning model so that the algorithm gives a positive outcome by analysing the labelled data.
