Over the past decades, machine learning has become one of the significant solutions in extracting and analyzing useful information from large-scale data. In addition to the field of data mining, the different Internet of Things (IoT), cloud computing, fog computing, and mobile cloud computing fields have adopted machine learning techniques to overcome several shortcomings in their decision-making process. Text classification, sentiment polarity, product or service recommendation, weather forecasting, stock price prediction, disease classification, attack detection, and spam classification are some of the emerging popular machine learning research areas.
