Enterprise Data Science Topics
It took Todd Lipcon 3 years to
create Kudu;10 years of work
before that learning and gaining
trust among OS Community as a
committer.
Government of the future:
value created through
interesting methods.
If your organization is already
good at the 5,000 Open Source
Algorithms (Regression etc), you
now need a Data Science Cadre.
Open Source: Help Wanted. Methods, not raw DataMost problems are not really
Data Science “Challenges”

Data Engineering and Data Science Workloads
Data Ingestion
(Kafka, Navigator,
Search)
Cloudera enables users to build real-time, end-
to-end data pipelines in order to power their
business. Leadership in Apache Spark and
Kafka have made Cloudera a trusted resource
for users who want to capture real-time,
streaming, and time series data without being
presented with gaps in security.
Data Processing
(Spark, Hive)
Cloudera is helping users accelerate
their data pipelines with leadership in
technologies like Apache
Spark. Data processing in Cloudera
Enterprise can help take processing
windows from hours to minutes and
enables faster access to data for a
variety of users and skillsets.
Data Science (Spark
MLlib)
Cloudera is bringing the most popular data
science languages/libraries to our platform
for easier collaboration, self-service
exploration, and implementation at
scale. Cloudera is advancing the state of
distributed machine learning at scale.
Cloudera enables exploratory data science
and the ability to deliver robust data
products.

Closing Gaps in Critical Skills Areas in the Govt
Data Science
High Value, Low Frequency
• Only a small set of problems require
direct Data Science expertise (~5%)
• Domain-general, algorithm-specific
• Very high expertise
Characterized by
• Spark/Python Expertise
• Advanced Algorithms
• Hypothesis-testing
Automation/Workload
• Per-task/Algorithm automation
Data Analysis
High Frequency, Self-Service
• The “other” 95% of Problems
• More domain-specific
Characterized by
• Tools with UI’s (Data Robot)
• “Exploratory” data investigation
Automation/Workload
• Easily automated
Data Science “Unicorns” are even more valuable in the Govt.
So how to you scale them out?

Two Data Science Use Cases
Improving decisions vs. improving products
Decision Science
(improving business decisions)
Data Products
(improving products for customers)
• User: Data scientists and analysts
• Data: New and changing; often sampled
• Environment: Local machine, sandbox cluster
• Tools: R, Python, SAS/SPSS, SQL; notebooks; data
wrangling/discovery tools, …
• Goal: Understand data, develop and improve models,
share results
• Production: Hosted/scheduled reports or dashboards
• User: Data engineers, developers, SREs
• Data: Known data; full scale
• Environment: Production clusters
• Tools: Java/Scala, C++; IDEs; continuous
integration, source control, …
• Goal: Build and maintain applications, improve
model performance, manage models in production
• Production: Online applications

Ingest
The Foundation of Hadoop’s Potential
Data can come from a variety of “siloed” sources
▪ Existing databases
▪ Sensor data
▪ Server logs
▪ Chat transcripts
Value of data is multiplied when combined and
correlated with other data
▪ “40% value improvement from combining data from
multiple IoT sources” McKinsey Global Institute

Data Processing
Leverage the right processing for your job
Data may require unique processing characteristics
▪ Batch
▪ Streaming
▪ Real-time
Hadoop arose to address one and now the ecosystem
has evolved to answer the rest.
▪ “We’re doubling down on Spark. We invested earliest,
and we’ve invested most, in making Hadoop
enterprise-grade” Mike Olson

Data Science
A Unified Platform to Accelerate Data Science from Exploration to Production.
Data Scientists need to use data to…
▪ Explore
▪ Model
▪ Test
The field of data science blends math and statistics
knowledge with advanced computer knowledge.
▪ “Data Scientist: Person who is better at statistics than
any software engineer and better at software
engineering than any statistician” Josh Wills

MLlib
Collection of mainstream machine learning algorithms built on Spark
Including:
•Classifiers: logistic regression, boosted trees, random forests, etc
•Clustering: k-means, Latent Dirichlet Allocation (LDA)
•Recommender Systems: Alternating Least Squares
•Dimensionality Reduction: Principal Component Analysis (PCA) and Singular Value
Decomposition (SVD)
•Feature Engineering & Selection: TF-IDF, Word2Vec, Normalizer, etc
•Statistical Functions: Chi-Squared Test, Pearson Correlation, etc
