As in past fifteen years with the ton of data accessible, machine learning has become one in each of the mainstays of data technology and thereupon, a rather central, albeit sometimes hidden, a part of our life. With the ever-increasing amounts of information changing into accessible, there's the sensible reason to believe that good data analysis can become additional pervasive as a necessary ingredient for technological progress. Machine learning is leverage of self-learning behavioral model. Through the past learning experience, the machine is used to extract hidden value from raw data. Data-intensive nature of machine learning makes it useful in the various aspect of life such as healthcare, marketing, automotive industry, information retrieval, intrusion detection, education and so on. This paper takes a review of various machine learning trends and application.
