ALUMNI CONNECT- "Machine Learning and Artificial Intelligence" by Mr.Nitin Aggarwal, Quantitaive Analyst, Google




The Department of Industrial and Management Engineering, IIT Kanpur had the opportunity to host a Webinar by Mr. Nitin Agarwal, Quantitative Analyst, Google. The Alumni committee of MBA holds the credit for organizing the webinar. An alumnus of MBA-IIT Kanpur, Nitin Agarwal gave a lot of insight into the world of Machine learning.  The webinar started with the speaker asking our views on Machine Learning. As he explained Machine Learning is the process of making lot of small decisions so as to get an end outcome. The basic objective of machine learning is not to memorize older data set but to recognize a pattern from the given data so as to be able to take decisions on newer data set.  This is where it differs from Statistics. While statistics draws inference answering the question “what does the data mean?”, machine learning is all about prediction, which answers the question “Does it work well?”.  So statistics describes data while machine learning takes decisions based on that data.  The industry is gradually moving from Statistics to Machine Learning.
The speaker next explained the different categories of Machine Learning which include: Supervised, unsupervised, semi supervised and reinforcement. In case of supervised learning all the images were labelled and in case of unsupervised learning the images were not labelled at all. In semi supervised learning while some images are labelled, some are not.  It is this semi supervised learning which is where the industry is currently focussing on. The speaker touched upon the neural network and deep learning.  He also explained the different technologies that extensively use machine learning.  Some notables are, IBM Watson, Google Prediction API, Tensor flow etc. As an MBA student it is imperative that we know how to take business decisions based on the inference drawn from the data.
Finally Mr. Nitin advised us what courses we can take over the MOOCs as well as in our department so as to build a strong foundation in Analytics. He categorically emphasized the importance of continuous learning in this fast changing world and the need to update ourselves to the changing need of the industry. It was a very insightful and informative session and would help people take an informed decision, who want to build a career in Analytics.

MBA @ IIT Kanpur: More than just an MBA

The season of summer internship has already started for MBA batch of 2013. All have already joined their respective summer-organizations and seem to be enjoying the work and the change. For some it’s a break from campus life and much awaited break from study. College graduates who don’t take a “working” break and join MBA program find an opportunity to earn their first salary-a beautiful experience which I need not explain for obvious reason. While the excitement among fresh college graduates about summer internship is understandable, experienced students cannot be left in exception either. They are found equally excited. Perhaps the break from study is the main reason. The formal attires, which feel ignored for a long time, find a chance to breathe in free air; otherwise the formal attires, at least at IITK, become like a bride’s Shadi ka joda which makes special and rare appearance only. However, when it comes to IIT Kanpur you find an exception. The excitement about summer int...
