About Me + My Interests
Currently I am the director of data
science in XBOX/Surface/Studios marketing working on consumer intelligence for
games, entertainment and devices.
I have worked on a variety of
problem spaces involving Big Data. Engineered intelligent
solutions using machine learning in various domains -
cloud services such as OneDrive/Sharepoint, search, recommendations, social
experiences, online advertisements,
knowledge bases, text mining and speech/speaker recognition, in the following
- Principal Applied Research Mgr, OneDrive & Sharepoint
- Responsible for data science & machine learning for
all of OneDrive & Sharepoint
- Principal Research & Development Manager, Bing
/ Bing Social Team
- Worked on creating Interest Graph to connect people
to topics of interest
- Shipped semantic expansions in Bing Sidebar "Friends
- Co-founder, R&D Lead,
Knowledge Web team @Microsoft.
scale Knowledge Bases
Bing Finance - knowledge driven finance portal, helping people make
- Designed & built push-model apps for restaurant
recommendation (iPhone), short video recommendation (tablet)
- Senior Applied Researcher,
Microsoft adCenter Labs
- Lead R&D teams responsible for Contextual
prototypes, worked on Behavioral Targeting.
intelligence applied to understanding, organizing,
tagging & discovery in email
- Text mining, growing topic models, text
categorization, clustering, etc
- Audio/Speech enhancement/noise suppression using
adaptive regression models for
Bell Labs - large scale speech and
speaker recognition, microphone arrays
Some recent projects for which I managed the applied
Much of this work was on "finding connections that interest you". It is about helping people discover
things that interest and delight them & help them make better decisions. For
this, I have used data mining, machine learning, semantics & recommendations. I have
worked extensively in various aspects of this space:
- content understanding (semantics, knowledge bases, text
mining, query & document to topic mapping, content similarity)
- user understanding (interest graphs, interest modeling)
- context modeling (context genomes, appropriateness of content to context, etc)
- recommendation engines (movies, XBOX Live
games using collaborative & social filtering, restaurant, video recommendation)
- experiences (mobile, tablet & web experiences)
- Interest Graphs.
One simple example of what we have enabled is if you
search on Bing for "meat dress costume" we connect you in
the Sidebar to Facebook friends who like Lady Gaga.
- In the Knowledge Web team, we built the
very first large scale knowledge graph in Microsoft, which
has become the seed for Bing's own knowledge graph. On top
of this, we built experiences for discovery of knowledge.
The example here also shows ads that are semantic.
- Our first knowledge base was in personal
finance, and was the primary driver for Bing Finance. One
example of what we did was to provide alternate
recommendations when searching for a stock - other "higher
dividend paying", "top buy rated in the same sector",
"having similar PE ratio" etc. which helped people make
better stock picking decisions
- We also built recommendation apps
advanced a "push" paradigm (restaurant recommendation on a
mobile phone & video recommendation on tablet). They had
well-integrated social experience (Facebook friends), worked
on "context genomes" and "taste mash-ups"
