Microsoft AI Platform - AETHER Introduction

3. Agenda
Scaled out AI Platform with Search (Bing and
Ads)
AI Platform is now used across Microsoft
Microsoft needs and drives Open and
Interoperable AI
Azure AI Services

4. Several Billion dollar AI businesses at
Microsoft
Learned a ton as we built them

6. How

7. Bing Ads Execution
 Shipped once every 6 months
 3 experiments / month
 Big bets that didn’t work.
 Created dev teams with core metrics
 Pushed teams to move their metric
 Developed AI Infrastructure to do
rapid experimentation.
 Over a few years made >300x
improvement (1000/mo expr)

8. Experiment – 90% of ideas fail
Iterate – faster you try things, the more successful ideas you have
Build Infrastructure to enable fast iteration of experiments

10. RPM Gains

12. Search Scenario Evolution
Keyword Based Search
Natural Language Search
Voice, Vision, Context-Based Search

13. How to ensure best results?

14.  Vector-based search:
 Word is represented as vector.
 Vector captures word meaning – its semantics.
 Words with similar meanings get similar vectors.
 In Bing, we trained a GloVe model over
Bing’s query logs and generated 300-
dimensional vector, enabled by deep
neural network.
Deep Learning: Semantic Understanding

15. Vector-based Retrieval
 DL-generated vectors semantically represent queries, documents and passages
 Doc retrieval based on query-doc-passage semantic similarity (vector distance)
AND

20. AI Expands Beyond Bing

21. AI Transforms all businesses across Microsoft
 AI is now done in almost every team
 Products that don’t seem to obviously use AI are powered by it
 Using the same tools and infrastructure to accelerate new teams

22. Took some time to warm up to the ideas…
To: Eric Boyd
From: xxxxx
Subject: ABC Experiment
…we have decided to ship the
XXX feature without running
the experiment first. We’re
quite confident in the
feature.
Our teams have a rich history
of shipping features without
any experimentation, something
that may be alien for folks
from Bing.

Subject: Re: ABC Experiment
I have a rich history of
driving my car with my eyes
closed. I’m quite confident I
know the way to work and have
only crashed a few times.

36. Hyperparameter Tuning
 As the models get more complex, the
space of hyperparameters to explore
increases exponentially!
 Grid or Random Search becomes too
costly
 Bayesian Optimization is used to optimize
Acquisition Functions

37. AI Platform

Built an exabyte-scale data lake for everyone
to put their data of all types (structured and
unstructured)
Built AI tools approachable by any developer
Built machine learning tools for collaborating
across large experiment models
