MACHINE LEARNING [Hands-on Introduction of Supervised Machine Learning Methods] DURATION 2 DAY
The field of machine learning is concerned with the question of how to construct computer programs that automatically improve with experience. - Tom Mitchell < M A C H I N E L E A R N I N G > Data generated through our activities captures plethora of information about our identity, likes and dislikes etc. This information has tremendous value in every aspect of human life. Programming computers to unravel this hidden information is what Machine Learning is all about. It is the art and science of scientifically deriving insights, patterns and predictions from data. Though it has been an area of active research for over 50 years, Machine Learning is currently undergoing a renaissance driven by Moore's law and the rise of big data. Large private and public investment in the area has given us self-driving cars, practical speech recognition, effective web search, and a vastly improved understanding of the human genome. Computer based Machine Learning algorithms now outperform humans on tasks such as handwritten digit recognition, traffic sign recognition, and even on some complex reasoning tasks as demonstrated by IBM's Watson winning Jeopardy Machine Learning models and programs automatically make decisions from data in order to achieve some goal or requirement. Machine learning models matter to the world. Because they are; #EFFICIENT Machine Learning models predict and detect partners faster than any other manual program or method. #EFFECTIVE Machine Learning models can do better job than humans when analysing and predicting large scale and streaming data sets (big data). #SCALE Machine Learning models can provide solutions to large data problems that traditional systems can not solve.
Over the past two decades Machine Learning has become one of the mainstays of information technology and with that, a rather central, albeit usually hidden, part of our life. With the ever increasing amounts of data becoming available there is good reason to believe that smart data analysis will become even more pervasive as a necessary ingredient for technological progress.

MACHINE LEARNING This course is meant to be a fast-paced, hands-on introduction to Machine Learning using R. The course will be focusing mainly on basics of Machine Learning methods and practical implementation of these methods to solve real-world problems. This course aims to develop basic understanding of supervised learning methods, through the use of the R programming platform. It describes the different types of learning and the two main categories of their applications: Classification and Regression. With a focus on the former, it takes a close look at typical Machine Learning techniques and how they apply on datasets akin to those encountered in the real world. Our goal is to give you the basic skills that you need to understand supervised Machine Learning algorithms and models, and interpret their output, which is important for solving a range of data science problems. Without getting too much into the mathematics of Machine Learning, this course dwells on the ideas and principles of it, along with the two main methods that all Machine Learning practitioners use. With theory and hands-on sessions intertwined, the course illustrates the usefulness of Machine Learning and how you can learn it effectively without losing sight of its elegance and value. Apart from the Classification techniques, you will learn about how to validate any classifier's performance, when to use what, and how the new innovations come about. The ability to take data - to be able to understand it, to process it, to extract value from it, to visualize it, to communicate it - that s going to be a hugely important skill in the next decades.
