Free Online Courses: Learn About Big Data, Blockchain, Artificial Intelligence etc.


Artificial intelligence, cryptography, data science and the like are much-talked about these days. Time for you to find out more. There are many free online courses to wrap your head around the latest technology. We present three of them.

Online courses are an ideal way to learn new skills and to keep yourself up to date with the latest technologies. Moreover, you can make use of e-learning wherever and whenever you like.       

Big Data Analytics in Healthcare by Udacity

In the Udacity course Big Data Analytics in Healthcare you will learn that data science plays an important role in many industries. In facing massive amount of heterogeneous data, scalable machine learning and data mining algorithms and systems become extremely important for data scientists. The growth of volume, complexity and speed in data drives the need for scalable data analytic algorithms and systems. In this course, we study such algorithms and systems in the context of healthcare applications.

In healthcare, large amounts of heterogeneous medical data have become available in various healthcare organizations (payers, providers, pharmaceuticals). This data could be an enabling resource for deriving insights for improving care delivery and reducing waste. The enormity and complexity of these datasets present great challenges in analyses and subsequent applications to a practical clinical environment.

Udacity offers a wide variety of free online courses as well as fee-based nanodegree programs in several disciplines like programming, data science, artificial intelligence, blockchain and virtual reality just to name a few. Online classes are very comprehensive including interactive content, industry experts, real-world projects, a large learning community and even career guidance. There are several free courses about deep learning, machine learning and artificial intelligence.

In the deep learning course for instance, you will get an overview of what deep learning is all about. Partnering with Vincent Vanhoucke, Principal Scientist at Google, and technical lead in the Google Brain team, you will learn how deep learning builds on machine learning. Then you will get a chance to learn more about deep neural networks and advanced architectures such as convolutional networks and recurrent networks.

Cryptography Online Course by Khan Academy

Khan Academy is sponsored amongst others by Bill Gates and Google and offers an introductory course to cryptography called Journey to Cryptography, which tries to answer the following questions: How have humans protected their secret messages through history? What has changed today? What happens, if two people can never meet to share a key in the first place? Why do primes make some problems fundamentally hard? Would access to coin flips speed up a primality test? How would this work?

Assess your understanding of the code breaking presented in the ancient cryptography lesson. Try your hand at real-world code breaking. These lessons provide a foundation for the mathematics presented in the modern cryptography tutorial. All online courses are free of charge and thought via videos, tutorials, tasks as well as quizzes. Udacity offers a similar course called Applied Cryptography. Cryptography is present in everyday life, from paying with a credit card to using the telephone. Learn all about making and breaking puzzles in computing.
