AWS Machine Learning: A Complete Guide with Python


AWS Machine Learning A Complete Guide With Python

Happy to announce that I launched a new course on AWS Machine Learning. Available on Udemy.com.

Learn about cloud based machine learning algorithms and how to integrate with your applications

Biggest challenge for a Data Science professional is how to convert the proof-of-concept models into actual products that your customers can use. Traditional approaches take too much effort and time to convert the model into a scalable product.

With AWS Machine Learning service, you can very easily conduct experiments and test your concepts. Once you are happy, you can instantly scale to support millions of requests.

Take a look at several free Preview videos. All lectures in Section 3 and Section 4 on Linear Regression are available for preview as well as Section 15 Integration objectives.

Network and Subnet Primer for AWS Virtual Private Cloud

In this video, I will explain all the concepts you need to understand on network and subnet addressing. If you are working on Amazon Virtual Private Cloud (VPC), you have the power to create your own private data center with different subnet depending on your needs.

To fully take advantage of VPC, you would need basic understanding on network and subnet addressing convention used and what they represent.

.Net Regular Expressions

Learning Regular Expression with .Net is a hands-on course that is designed to make you an expert in regular expressions.

This course contains over 25+ hands-on exercises, practical tips, quizzes and three projects to apply the new skills you learned in this class.  In the first project, we will be extracting useful information from unstructured text data from Robocopy tool, in the second project we will be on working on large data set generated by Sensors and in the third project we will look in to Health Care Systems that deal with Electronic Medical Records.  These exercises will demonstrate that with regular expression you can implement complex parsing with only a few lines of code
