The Great Precog Expedition

It all began with searching for opportunities to work in the summer of 2016. I had heard endlessly about the work culture at IIIT Delhi, the research groups and the out of this world faculty. After researching through the site, I stumbled upon Professor PK’s profile. As I read further about him, I was awestruck and amongst the many who would want to work with PK.

My first meeting with him lasted for roughly 15 minutes but I went back home with a bag full of riveting information about what it takes to be a Precog-er. This was also the first time I got to know about Randy Pausch. At home, I watched ‘The Last Lecture’ and understood why the walls of the Precog area are adorned with his quotes.

Soon after I took part in the OSMpalooza Hackathon and witnessed firsthand how quick progress is made by students here. My team came up with whatever best solution we could think of, for the problem statements given. Sadly, my team didn’t win a position but I witnessed some amazing solutions by other teams and most importantly I saw myself serious and engrossed in a project in Social Media Analysis. This was the time I was further sure of wanting to work in Precog since majority of the work is done on analysing social media content. This incident would be incomplete without quoting the following:

“Experience is what you get when you didn’t get what you wanted. And experience is often the most valuable thing you have to offer.” –Randy Pausch

Very soon, I applied for the internship. After an intricate interview process, I received my offer letter. My first day at Precog was a Brainstorming session (which is another bonus point of this internship). Before the internship, how I went through research papers was basic skimming. And in the first session itself, I witnessed the dissection of a paper and not only deriving the entire methodology, but also discussing elaborate ideas about extending the current paper and implementing those as well. This is just one example of how working at Precog means legit serious work.

I was lucky to have Prateek Dewan as my mentor during the internship period. I started working closely with Prateek and soon after there were series of things I learnt that I apply till date. Before the internship the only language I worked in was Java and by the end of it, I had another language i.e. Python, to add to my skill set. Each little doubt regarding my project was cleared by him and he promptly replied to any query I had at any odd hour. I was a little apprehensive in the beginning since the progress made at Precog is super quick but I learned it all in my own time.

The most incredible characteristics of this group are the levels of sincerity and passion shared by each Precog-er when it comes to work. Apart from the respective projects carried out by each group, the regular Brainstorming sessions covered the latest research topics extensively. Several new ideas and information about the tech world were discussed in the mailing list and very soon I got the hang of it. One particular email comprised of PK discussing his latest choice of book to read, “Eat That Frog!” By Brian Tracy. Being an avid reader, I bought it the next day itself and the book has had phenomenal influences on my life. (amazing book suggestions!; another bonus of the internship). Striking a balance between working and having fun is another take away. The binding force of Precog is PK and the smart-working researchers, known as Precog-ers, make this group what it is.

Why I chose such a heavy sounding title for this post is because Precog can’t be defined by anything less. It is indeed a great expedition and I am fortunate to have experienced it.

I would like to end by quoting my favourite Randy Pausch saying that has now adorned my room’s wall as well:

“The brick walls are there for a reason. The brick walls are not there to keep us out. The brick walls are there to give us a chance to show how badly we want something. Because the brick walls are there to stop the people who don’t want it badly enough. They’re there to stop the other people.”

The Precog Journey

I had an inclination towards research ever since I joined IIIT-D. I admired my Seniors who got admits from the Best CS Universities of the world, which felt like the next milestone to achieve. Looking at the profiles of several of them, I realised that there was an eminent underlying force behind, that was PK! I was awestruck by the posts that PK used to do about the achievements of his students on Social Media.

I had done research in the Security domain during my first 2 years and Security in Social Media looked like a fascinating field to explore. I joined the DHCS course in the beginning of 2016, that’s when I got to interact with PK. His way of teaching is unique, and he instills an aura of enthusiasm and interest as he delivers lectures.  From him I got a new perspective to look and analyse the everyday interfaces.

I decided to apply for an Internship with Precog for the Summer of 2016. The interview was grilling and I kept my fingers crossed till the result was announced. After receiving acceptance from Precog I also received an Internship Offer from IBM Research Labs. I was faced with a dilemma, both being Great Research opportunities. I talked to PK and he offered me a part time internship with Precog.

I was excited to start working with the group. Anupama introduced me to the problem statement we were going to be working on, “Privacy Leaks through Browser Extensions”. I was thrilled to know that we were going to have a collaboration with Bimal Viswanath from Bell Labs. I had read his research papers before and was intrigued by his findings. Working with Precog feels like, you have been blessed with a network of the Top researchers across the globe with whom you can discuss, learn and work.

I moved to Bangalore to join IBM Research and worked remotely. I used to stay in office till late night reading Papers, and also Precoged during the weekends. PK used to be in constant touch as my guide and a mentor. Precog felt like a family and working on the Research Project was fun. Whenever I was stuck anywhere I was offered full support, I could message anytime and Anupama was lightning fast with her replies. I learnt the Skills of collaboration, time management and most importantly smart-working rather than hard-working.

Coming back from Bangalore I was in full swing to join the group with vigour. PK always has suggestions to improve efficiency and quality, his visions and ideas can be clearly seen imbibed in the group. Attending regular meetings, ‘whatsup’ and BM sessions, I have learned far too many things to be enumerated. Earlier I was intimidated by the rapid progress of the group, now I take pride with every new accomplishment of every member. Since every other day there is a new achievement being discussed in the group’s mailing list. Association with Precog has been a Roller-Coaster ride, where we have worked as team and partied as friends. I have been really lucky to be associated with the Coolest Research Group of IIIT-Delhi.

Preventing KillFie: A crowdsourced approach

Selfies have become a prominent medium for self-portrayal on social media. Certain social media users go to extreme lengths to click dangerous selfies, which puts their lives at risk. A hundred and twenty seven individuals have died since March 2014 until December 2016 while trying to click selfies out of which 76 deaths were from India alone.

This disturbing trend can be traced to users taking selfies in “dangerous” locations which in turn can be linked to the concept of self representation on online social media. A user will be perceived more bold and adventurous if he posts from a cliff top or in front of a moving train. Such acts of portraying oneself as being a daredevil leads people to go to life threatening lengths to get the perfect selfie. The engrossing hunt for the ultimate display picture momentarily distracts the selfie taker from their surroundings, which might result in tragedies.

Our goal is to get a dataset of all such locations around the globe which are popular selfie spots, but the lives of people clicking selfies at these locations are inadvertently put at risk. We go about collecting this data through an android app and a chatbot(on facebook) that we made. Users can report locations along with the type of risk(eg : height related, water related, vehicle related etc) associated with taking a selfie on that location. Using this data, our app nudges the user (through a notification) whenever the user goes near such a location.

As we become more engrossed in mobile phones, and go to extreme lengths while being absorbed in our phones and digital world, it is possible that we lose sense of our physical surroundings. For instance, there were several incidents when people got injured while using Pokemon Go (an immersive augmented reality application). Tagging such dangerous locations might be helpful for such apps to get relevant warnings from the database.

If you know of a selfie lover or are one yourself, please download this app. Even a single location which you report may prevent many unfortunate deaths. And since what goes around comes around, one day the app might save you from unknowingly putting yourself in danger.

To interact with the chatbot, go to the facebook page and click on send message. Send a location by clicking on the location icon(can be done only through the messenger app) and just follow the instructions given by the bot.
