Cleaning and enrichment of data
Crossing data
Each street is segmented into small pieces that are enriched with geospatial information.
The parking ticket history is joined with the points of interest from OpenStreetMap.

Creation of a predictive algorithm
The availability of parking lots is predicted by street segments from the joined data.

Web logs
Words within the requests are analysed by the studio.
Web logs with clicks and bounce rates are imported in the studio.
Data cleaning and enrichment
Customized algorithm
The Data Science team of PagesJaunes identifies unsuccessful searches and train a customized algorithm. Web logs are enriched (time spent on the website per user, localisation, etc.)
Algorithm used
with all data
Long-­‐term monitoring of unsuccessful searches
Dataiku’s technology enabled us to rationalise our work thanks to machine learning on millions of searches.
The process is optimized, we know what and how to do it. Erwan Pigneul, www.dataiku.com

“Data Science “I spend too much time Superstars are cleaning up my data really hard to hire.” with inappropriate tools.”
“Our models are quite difficult to set up so they are rarely deployed into production.”

“There is too much plumbing involved in making all these Big Data technologies work together and then in successfully deploying applications with them.”
Data Science Studio
A studio for all your data driven applications
Load and prepare

your projects
For all profiles Collaborative Open and controlled
www.dataiku.com
Data preparation
• Connect to all your data sources • Explore them visually • Transform and enrich them interactively • Save your ‘recipes’ and reuse them later
www.dataiku.com
Analyse and model
• Discover correlations and significant variables • Easily build your first models in a visual interface • Test and improve several models alongside one another • Deploy the models’ results directly inside your infrastructure
www.dataiku.com
Deploy into production
• Go quickly from prototypes to large scale production • Manage data inputs and outputs from the interface • Export and publish your results in several forms • Control the updates with options such as scheduling, partitions, and replications…
www.dataiku.com
Collaborative work
• Enjoy a web interface and a shared platform • Organise your work by projects and by teams • Reuse the team’s work at any time • Make sure everyone is always on the same page: share insights, graphics, comments, etc. with your team
www.dataiku.com
Open and controlled
• Take advantage of open source technologies such as Hadoop, iPython,
scikit-­‐learn, R… • Integrate your own libraries and scripts
• Keep the data safe in your own infrastructure • Keep your innovations under control: algorithms and predictions belong to you
