A Successful Machine Learning Bootcamp by CloudxLab

CloudxLab has hosted several webinars in the past and all of them have been successful. But this time we thought to try something different. So, we all sat together and decided to do an offline meetup for Machine Learning. Though we had done some in the past, the engagement and interaction that one can get in the online webinar are not comparable. Anyhow, we then got in touch with Drupal Bangalore and they were having this event in R. V College of engineering. And one of the topics was Introduction to Machine Learning. We found this a good opportunity to bring our knowledge in the offline circle too.

Machine Learning Bootcamp

So it all happened on Nov 17 where Machine Learning enthusiasts gathered to attend the one day workshop on Machine Learning. The presenter was none other than Mr. Sandeep Giri, who has over 15 years of experience in the domain of Machine learning and Big Data technologies. He has worked in companies like Amazon, InMobi, and D. E. Shaw.

What is Big Data? An Easy Introduction to Big Data Terminologies

Unless you’ve been living under the rock, you must have heard or read the term – Big Data. But many people don’t know what Big Data actually means. Even if they do then the definition of the same is not clear to them. If you’re one of them then don’t be disheartened. By the time you complete reading this very article, you will have a clear idea about Big Data and its terminology.

What is Big Data?

In very simple words, Big Data is data of very big size which can not be processed with usual tools like file systems & relational databases. And to process such data we need to have distributed architecture. In other words, we need multiple systems to process the data to achieve a common goal.

1. What is Apache Spark and what are the benefits of Spark over MapReduce?

  • Spark is really fast. If run in-memory it is 100x faster than Hadoop MapReduce.
  • In Hadoop MapReduce, you write many MapReduce jobs and then tie these jobs together using Oozie/shell script. This mechanism is very time consuming and MapReduce tasks have heavy latency. Between two consecutive MapReduce jobs, the data has to be written to HDFS and read from HDFS. This is time-consuming. In case of Spark, this is avoided using RDDs and utilizing memory (RAM). And quite often, translating the output of one MapReduce job into the input of another MapReduce job might require writing another code because Oozie may not suffice.
  • In Spark, you can basically do everything from single code or console (PySpark or Scala console) and get the results immediately. Switching between ‘Running something on cluster’ and ‘doing something locally’ is fairly easy and straightforward. This also leads to less context switch of the developer and more productivity.
  • Spark kind of equals to MapReduce and Oozie put together.

SCMHRD Partners With CloudxLab



In a recent strategic partnership that demonstrates SCMHRD’s superior vision in pedagogy, the Post Graduate Program in Business Analytics (PGPBA) has tied up with well known learning innovation firm CloudxLab. With this partnership, SCMHRD’s students will get to learn and work with Big Data and analytics tools in the same manner that enterprises learn and use them.

SCMHRD’s flagship Analytics program PGPBA with its emphasis on Big Data analytics, as opposed to standard analytics, makes it relevant to a bigger gamut of employers and hence the better choice. This emphasis isn’t easy to cater to. Providing Big Data tools to learners entails providing a cluster (a bunch of computers) that they can practice on which in turn translates to expensive infrastructure, big support teams, and the operational costs that go with everything.
