3. “Machine learning is a core,
transformative way by which we’re
re-thinking how we’re doing everything”
Sundar Pichai
CEO, Google

4. “Machine learning will cause every
successful huge IPO win in 5 years.”
Eric Schmidt
Executive Chairman, Alphabet

12. Machine Learning at Google

13. Products using Machine Learning

19. TensorFlow

21. ● Open source Machine
Learning library
● Especially useful for
Deep Learning
● For research and
production
● Apache 2.0 license

22. Raspberry
Pi
DatacentersYour laptop Android iOS
Portable & Scalable

23. A multidimensional array.
A graph of operations.

24. Data Flow Graphs
Computation is defined as a directed acyclic graph
(DAG) to optimize an objective function
● Graph is defined in high-level language (Python)
● Graph is compiled and optimized
● Graph is executed (in parts or fully) on available low
level devices (CPU, GPU)
● Data (tensors) flow through the graph
● TensorFlow can compute gradients automatically

Cloud Vision API

34. Confidential & ProprietaryGoogle Cloud Platform 34
Cloud Natural Language API
Extract sentence, identify parts of
speech and create dependency parse
trees for each sentence.
Identify entities and label by types such
as person, organization, location, events,
products and media.
Understand the overall sentiment of a
block of text.
Syntax Analysis Entity Recognition
Sentiment Analysis

35. Confidential & ProprietaryGoogle Cloud Platform 35
Cloud Speech API
Automatic Speech Recognition (ASR)
powered by deep learning neural
networking to power your
applications like voice search or
speech transcription.
Recognizes over 80
languages and variants
with an extensive
vocabulary.
Returns partial
recognition results
immediately, as they
become available.
Filter inappropriate
content in text results.
Audio input can be captured by an application’s
microphone or sent from a pre-recorded audio
file. Multiple audio file formats are supported,
including FLAC, AMR, PCMU and linear-16.
Handles noisy audio from many
environments without requiring
additional noise cancellation.
Audio files can be uploaded in the
request and, in future releases,
integrated with Google Cloud
Storage.
Automatic Speech Recognition Global Vocabulary Inappropriate Content
Filtering
Streaming Recognition
Real-time or Buffered Audio Support Noisy Audio Handling Integrated API
