AI/ML in Flipkart--CTO Talk event experience

Our team has done some Machine Learning projects. When it comes to recommendation system, my favorite has been so far PredictionIO which was based on Apache Mahout (Now they have switched to Spark). I was also avidly learning Machine Learning for some time. My boss suggested me to attend the CTO Talk event hosted by OrangeScape. Its first session is “AI/ML in Flipkart” by Flipkart CTO Ravi Garikipati. As I mentioned earlier, I always had my skepticism towards these buzz words.  But, this presentation changed my perspective for good.

Event

The event started with welcome note by Rajesh Manickadas, Head of Engineering, OrangeScape. Then OrangeScape CEO Suresh Sambandam quickly introduced and handed over to Ravi Garikipati.

Flipkart CTO Ravi Garikipati


Ravi explained his journey from TCS in 1988 to IBM, Oracle, etc. He explained his earlier attempts of AI based virtual assistant for [24]7. Also, quickly connected with the audience through his remark about his connection with Chennai and why—his wife and his in-laws.

AI/ML in Flipkart


Ravi then went on to explain the challenges in India and why it needs homegrown MI solution.
  • Flipkart is collecting everything-- from users’ GPS location to page scroll
  • On an average, Flipkart generates 10 TB of data per day; it goes up to 50 TB on sales days like Big Billion Days.
  • Flipkart answer for MI challenge is FDP (Flipkart Data Platform)
  • FDP is built based on Hadoop, Hive, Cassandra, Power BI
  • Flipkart is also investing in GPU based hardware as doing Machine Learning in Laptop will take ages.
  • In India, with respect to data, the challenge is that the whole family may use same account and credit card details. So, personalization is kind of a challenge.
  • Flipkart has open sourced its text processing library called “FastText” (Unfortunately, I can able to find Facebook’s fastText library alone)

Applications

  • From their FDP ML studio, they’re inferring 40+ insights like infographics, brand affinity, fraud, etc
  • Trying to show different homepage for tier-2 places for price and other reasons
  • Trying to show different recommendations for different customers based on price, brand, etc
  • Trying to show trending products and mobile models to mimic real time salesman feedback
  • Trying to understand why they have 30% bounce rate
  • Showing similar dresses based on “features” instead of mere colors
  • In Myntra, they generate rapid designs. Their system comes up with new designs for apparels. They’re sourcing from Tiruppur and Ludhiana; but for designs previously they have to rely on France.
  • Using data to launch their own private label products.
  • Using “contextual NLP” to process sentiments
  • Using NLP and ML for cleaning up reviews (auto titling, fix rating, handle profanity, understand Hinglish)

Ravi’s approach/framework

Ravi suggested that we should always have “AI first vision”. To arrive intuitive features, it is important to know the business.

Audience Interaction

I asked him if they have any plan to open up their FDP to outside. Ravi said they have no plan to launch it as a prediction service. (This is kind of disappointing for me.)

Someone asked if they have any plan to use trust framework like Blockchain. Ravi said they’re using Blockchain in their fintech venture, but not here.

Another person asked why their app is not using AI and he compared it with another Chennai based Startup Mad Street Den. Ravi humbly said he even talked to Ashwini of Mad Street Den and will try to work on improving.

Suresh asked as he heard that in US, Google is panic about Amazon and if similar things are happening with Flipkart. Ravi said, many brands have realized to put ad in the final destination and in Flipkart also they’ve seen huge Ad revenue.

My Personal Take-away

  • Earlier, I was unclear why Flipkart is paying huge salary for its talents and CTO. Now, I realized only companies like Flipkart has the scale to retain such huge talents like Ravi.
  • Ravi’s presentation changed my perspective towards Machine Learning. Ravi’s framework of “AI first thinking” is a good idea.
  • I came to know about INSOFE, Hyderabad. Ravi was sharing good feedback about it. (But, in Quora and Google Reviews, this training institute is having mixed reviews.)
  • Came to know about OrangeScape. I searched and found their product KiSSFLOW. They served coffee and tea, but I’m not sure, why they didn’t promote them. Their office space is quite creative with Tamil inscriptions and interior works. I thought of taking photos and felt that it may not be appropriate without proper permission and so avoided.
  • Also, came to know about Mad Street Den, the Chennai based startup doing AI related works. Probably, it would be a good opportunity to interact with its CEO Ashwini, in another event?

Stampede and the "Dirty" "Dark" Crowd

Actor Ajith Kumar’s recent interview has sparked quite a few conversations on social media. The part that caught my attention, was his take on crowds. About 30 years ago, when I first joined a college in Madurai after growing up in other places, I experienced a few cultural shocks. Perhaps these weren’t unique to Madurai, but that’s where I first noticed them. One major thing that stood out was the behavior of crowds. For instance, if you suddenly see people rushing to board a bus, chances are there’s a pickpocket in action. During one of Madurai's annual festivals, I noticed some young men carrying water bags — not to distribute water, but to spill it on women, often on their chests. Shockingly, this was almost normalized; parents would quietly tolerate it to avoid public embarrassment, walking a little farther behind the crowd. When some women happened to witness this, they would just shoo the boys away instead of confronting them. The crowd, in such cases, became a kind of...

Valen Smith, the English teacher videos are missing!

I vaguely remembered that sometimes around 2009, engVid on YouTube was very popular. I especially liked a teacher by name Valen Smith's videos. She was not only beautiful but also very good at explaining the English usage. I also vaguely remembered to check her channel ValenESL around 2015. But, not sure what happened to her or engVid, all her videos are sadly gone. I have also noted that many people on Twitter were asking the same. Not sure what happened. Some people seem to have reuploaded her videos and YouTube continuously removing them with a note "This video contains content from LearnVid, who has blocked it on copyright grounds." Strangely though, on Facebook, some people have managed to create a fake account using her old channel name ValenESL.

Interview question #1

Since I have been asked to interview experienced PHP programmers, I was preparing few interview questions. I came to know, most of the people ask questions found in the Internet; most of them are like "What is the function used to connect MySQL DB in PHP". Personally, I don't like these types of questions; I'd thought the person must apply ideas what he was taught in colleges--finally I came out with one question: A product vendor has Quantity Vs. Price data like 1 -> Rs. 50 2 -> Rs. 95 3 -> Rs. 140 .... like upto 1 million data. He wants a system, which gives the price when the quantity is provided. For example, if you provide the quantity value as 2, then it should provide Rs. 95. How this system can be designed? As expected, all the people said about using database tables and quering on quantity. I have asked them to find out a system which doesn't use databases--provided the accuracy of the system may not be 100%--it may give at least 90% ac...
