Data Science….Still Magic?

It ’s not a trick, it ’s an illusion.

Any sufficientlyadvanced technology isindistinguishable from

magic.— Arthur C. Clarke

1. create technology:people who are not experts canuse it easily with little difficultyand trust the output

2. make it “sufficiently advanced”

1. Counting stuff

2. Figuring out the denominator

3. The reproducibility of 1 & 2• *

Data Science in the Enterprise

Seems like magic…

But it boils down to 2 factors….

Data Science Success Factors in the Enterprise

• Building a great data science infrastructure

• Solving the last mile problem

Tricks to build a great data science infrastructure

Trick#1: Centralized Data Aggregation…

Goals & Challenges

• Correlate data from disparate data sources

• Enable a centralized data store for your enterprise

• Incorporate new information sources in an agile way

• Traditional multi-dimensional data warehouses are difficult to modify

• They are designed around a specific set of questions (schema-first)

• Challenges to incorporate semi-structure and unstructured data

I would like to… But…

Centralized Data Aggregation: Best Practices

• Implement an enterprise data lake

• Rely on big data DW platforms such as Apache Hive

• Use a federated architecture efficiently partitioned for different business units

• Establish SQL as the common query language

• Leverage in-memory computing to optimize query performance

Centralized Data Aggregation: Technologies & Vendors

Trick#2: Data Discovery…

Goals & Challenges

• Organically discover data sources relevant to my job

• Help others discover data more efficiently

• Collaborate with colleagues about specific data sources

• Business users typically don’t have access to the data lake

• There is no corporate data repository

• There is no search and metadata repository


Data Discovery: Best Practices

• Implement a corporate data catalog

• The data catalog should be the user interface to interact with the corporate data lake

• Copy ideas from data catalogs in the internet

• Provide rich metadata experience in your data catalog

• Extend your data lake with search capabilities

Data Discovery: Technologies & Vendors

Trick#3: Establish a Common Query Language…

Goals & Challenges

• Query data from different business systems in a consistent way

• Correlate information from different line of business systems

• Reuse queries as new sources of information

• Different business systems use different protocols to query data

• I need to learn a new query language to interact with my big data infrastructure

• Queries over large data sources can be SLOW


Query Language: Best Practices

• Standardize on SQL as the language query business data

• Implement a SQL interface for your data lake

• Correlate data sources using simple SQL joins

• Materialize query results in your data lake for future reuse

• Invest in in-memory technologies to optimize performance

Query Language: Technologies & Vendors

Trick#4: Focus on Data Quality…

Goals & Challenges

• Trust corporate data for my applications

• Actively merge new and historical data

• Integrate new data back into line of business systems

• Data in line of business systems in poorly curated

• Some data records need to be validated or cleanse

• Some data records need to be enriched with additional data points


Data Quality: Best Practices

• Implement a data quality process

• Leverage your data catalog as the main user interface to control data quality

• Trust the wisdom of the crowds to manage data quality

• Provide a great user experience to data quality

Data Quality: Technologies & Vendors

Trick#5: Understand your data….

Goals & Challenges

• Execute efficient queries against my corporate data

• Discover patterns and trends about business data sources

• Rapidly adapt to new data sources added to our business processes

• There is no simple way to understand corporate data sources

• We rely on users to determine which queries to execute

• New data patterns and trends often go undetected


Understanding your Data : Best Practices

• Leverage machine learning algorithms to understand business data sources

• Leverage clustering algorithms to detect interesting patterns from your business data

• Leverage classification algorithms to place data records in well-defined groups

• Leverage statistical distribution algorithms to reveal interesting information about your data

Understanding your Data : Technologies & Vendors

Trick#6: Predict…

Goals & Challenges

• Efficiently predict well-known variables in my business data

• Adapt results to future predictions

• Take actions based on the predicted outcomes

• Our analytics are based on after-the-fact reports

• Traditional predictive analytics technologies don’t work well with semi-structured and unstructured data

• Traditional predictive analytics require complex infrastructure


Predict : Best Practices

• Implement a modern predictive analytics platform

• Leverage the data lake as the main source of information to predictive analytics algorithms

• Leverage classification and clustering algorithms as the main mechanisms to train predictions

• Expose predictions to other applications for future reuse

Predict : Technologies & Vendors

Trick#7: Take Actions…

Goals & Challenges

• Not have to read a report to take actions on my business data

• Model automatic actions based on well-defined data rules

• Evaluate the effectiveness of the rules and adapt

• Data results are mostly communicated via reports and dashboards

• There is no interface to design rules against business data

• Actions are implemented based on human interpretation of data


Take Actions : Best Practices

• Implement a modern predictive analytics platform

• Leverage the data lake as the main source of information to predictive analytics algorithms

• Leverage classification and clustering algorithms as the main mechanisms to train predictions

• Expose predictions to other applications for future reuse

Take Actions: Technologies & Vendors

Trick#8: Embrace developers…

Goals & Challenges

• Leverage data analyses in new applications

• Help developers embrace corporate data infrastructure

• Expose data analyses to new mediums such as mobile or IOT

• Data results are mostly communicated via reports and dashboards

• Data analysis efforts are typically led by non-developers

• There is no easy way to organically discover and reuse corporate data sources


Leverage Developers: Best Practices

• Expose data sources and analyses via APIs

• Leverage industry standards to integrated with third party tools

• Provide data access samples and SDKs for different environments such as mobile and IOT clients

• Incorporate developer’s feedback into your data sources

Take Actions: Technologies & Vendors

Trick#9: Real time data is different…

Goals & Challenges

• Process large volumes or real time data

• Aggregate real time and historical data

• Detect and filter conditions in my real time data before it goes into corporate systems

• There is no infrastructure to query real time data

• We process real time and historical data using the same models

• Large data volumes affect performance


Real Time Data Processing: Best Practices

• Implement a stream analytics platform

• Model queries over real time data streams

• Add the results of the aggregated queries into the data lake

• Replay data streams to simulate real time conditions

Real Time Data Processing: Technologies & Vendors

Solving the last mile problem

Trick#1: Killer user experience…

Create a Killer User Experience

• Design matters

• Invest on a easy way for users to interact with corporate data source

• Leverage modern UX principles that work cross channels(mobile, web)

• Make data discoverable

• Leverage metadata

• Facilitate collaboration

Trick#2: Test test test…

Test Test Test

• Incorporate test models into your data sources

• Simulate real world conditions at the data level

• Assume everything will fail

Trick#3: Integrate with existing tools…

Integrate with Third Party Tools

• Integrate your data lake with mainstream tools like Tableau or Excel

• Use industry standards so that data sources can be incorporated

Trick#5: Collaborate…

Collaborate

• Integrate data sources with modern messaging and collaboration tools: Slack, Yammer etc

• Distribute updates via emails, push notifications, SMSs

Other things to consider

• On-premise, cloud or hybrid?

• Apply agile development practices to your data science infrastructure

• Infrastructure is cool but usability is more important

Summary

• Data science is not magic, is an illusion

• Implementing data science in the enterprise is about solving two problems• Building a great data infrastructure

• Solving the last mile usability challenge

• Today this can be done with commodity technology

• Data scientists are just “people “ ;)
