Join my Social Media Analytics sessions at Tableau Conference #data18

Are you ready for Tableau Conference 2018? Don’t miss my Social Media Analytics sessions!

Why do we need Social Media Analytics?

Social Media Analytics transforms raw data from social media platforms into insight, which in turn leads to new business value.

What will your learn in this sessions?

Once you dive into Social Media Analytics, how do you bring it to the next level? Social data can offer powerful insights right away. In this session, you will learn how to build a mature social data program from that foundation and strategies for scaling a social data programme, as well as how to connect directly to your social media data with a web data connector; considerations for building scalable data sources; and tips for using metadata and calculations for more sophisticated analysis.

Where and when are the sessions?

Digitale Banken: Welche Digitalisierungstrends bewegen die Finanzbranche 2018?

Immersive und interaktive Analyse von Finanzdaten mit Argumented Reality

Jedes Jahr (2015, 2016, 2017 und 2018) stelle ich Digitalisierungstrends vor, die der Finanzbranche ein großes Potenzial bieten. Dabei geht es vor allem um einen Überblick darüber, welche Trends und Technologien zukünftig eine größere Rolle spielen werden oder könnten.

Im Folgenden habe ich die fünf Digitalisierungstrends identifiziert, die für Banken und Versicherungen in Zukunft besonders spannend sein dürften:

1. Maschine Learning

Maschine Learning und Deep Learning werden im Investment Banking angewandt, um Unternehmensbewertungen schneller und zuverlässiger durchzuführen. Mehr Daten denn je können hinzugezogen werden. Eine Gewichtung der Daten erfolgt komplett autonom. Da manuelle Analyse weitgehend entfällt, werden Entscheidungsprozesse drastisch beschleunigt. Investoren, die mit konventionellen Werkzeugen arbeiten, haben das Nachsehen.

2. Künstliche Intelligenz

Durch Künstliche Intelligenz gesteuerte Chatbots vermitteln den Kunden eine menschlichen-ähnliche Betreuung. Chatbots werden darüber hinaus in existierende Cloud-basierende Assistenten, wie Alexa oder Siri, eingebunden und sind in der Lage mittels Natural Language Processing, auch komplexere Anfragen zu verstehen. Recommender-Systeme liefern maßgeschneiderte Lösungen, die speziell auf die Bedürfnisse der Kunden abgestimmt sind.

3. Internet of Things

Wearables und in Kleidung eingearbeitete Sensoren (Internet of Things, IoT) liefern ausreichend Daten, um den Lebensstil der Kunden vollständig zu vermessen. Dadurch können individuelle Raten für Versicherungen und Finanzprodukte berechnet werden. Außerdem bieten die IoT-Daten eine weitere Datenquelle für die Recommender-Systeme.

4. Blockchain

Verträge werden kostengünstig, fälschungssicher und irreversibel in der Blockchain gespeichert. Die Blockchain dienst sogenannten Smart Contracts als dezentrale Datenbank. Darüber hinaus liefern Blockchain-Implementierungen, wie Ethereum, das Ausführen von Logik, die beispielsweise monatliche Zahlungen prüfen und ggf. auch die Erfüllung von Vertragsbestandteilen (z.B. im Schadenfall) steuern.

5. Argumented Reality

Arbeitsplätze werden mit Technik ausgestattet, die Argumented Reality ermöglicht. Lösungen wie Microsoft’s Hololense ermöglichen Analysten und Händlern eine immersive und interaktive Analyse von Finanzdaten in Echtzeit. Insbesondere fällt dadurch auch die Zusammenarbeit mit Kollegen leichter, da Plattformen zur visuellen Kollaboration traditionelle Meetings weitgehend ablösen.

Welcher ist der 6. Trend?

Helfen Sie den 6. Digitalisierungstrend zu benennen? Nehmen Sie hierzu an der Twitter-Umfrage teil. Selbstverständlich freue ich mich auch über Kommentare und eine spannende Diskussion.

Data Science Toolbox: How to use Julia with Tableau

R allows Tableau to execute Julia code on the fly
R allows Tableau to execute Julia code on the fly

Michael, a data scientist, who is working for a German railway and logistics company, recently told me during an FATUG Meetup that he loves Tableau’s R and Pyhton integration. As he continued, he raised the raised the question for using functions they have written in Julia. Julia, a high-level dynamic programming language for high-performance numerical analysis, is an integral part of newly developed data strategy in the Michael’s organization.

Tableau, however, does not come with native support for Julia. I didn’t want to keep Michael’s team down and was looking for an alternative way to integrate Julia with Tableau.

This solution is working flawless in a production environment since several months. In this tutorial I’m going to walk you through the installation and connecting Tableau with R and Julia. I will also give you an example of calling a Julia statement from Tableau to calculate the sphere volume.

1. Install Julia and add PATH variable

You can download Julia from julialang.org. Add Julia’s installation path to the PATH environment variable.

2. Install R, XRJulia and RServe

You can download base R from r-project.org. Next, invoke R from the terminal to install the XRJulia and the RServe packages:

> install.packages("XRJulia")
> install.packages("Rserve")

XRJulia provides an interface from R to Julia. RServe is a TCP/IP server which allows Tableau to use facilities of R.

3. Load libraries and start RServe

After packages are successfully installed, we load them and run RServe:

> library(XRJulia)
> library(Rserve)
> Rserve()

Make sure to repeat this step everytime you restart your R session.

4. Connecting Tableau to RServe

Now let’s open the Help menu in Tableau Desktop and choose Settings and Performance >Manage External Service connection to open the External Service Connection dialog box:

TC17 External Service Connection

Enter a server name using a domain or an IP address and specify a port. Port 6311 is the default port used by Rserve. Take a look on my R tutorial to learn more about Tableau’s R integration.

5. Adding Julia code to a Calculated Field

You can invoke Calculated Field functions called SCRIPT_STR, SCRIPT_REAL, SCRIPT_BOOL, and SCRIPT_INT to embed your Julia code in Tableau, such as this simple snippet that calculates sphere volume:

6. Use Calculated Field in Tableau

You can now use your Julia calculation as an alternate Calculated Field in your Tableau worksheet:

Tableau Conference TC17 Sneak Peek: Integrating Julia for Advanced Analytics

We have already seen some love from Tableau for R and Python, boosting Tableau’s Advanced Analytics capabilities.

So what is the next big thing for our Data Science Rockstars? Julia!

Who is Julia?

JuliaJulia logo is a high-level dynamic programming language introduced in 2012. Designed to address the needs of high-performance numerical analysis its syntax is very similar to MATLAB. If you are used to MATLAB, you will be very quick to get on track with Julia.

Compared to R and Python, Julia is significantly faster (close to C and FORTRAN, see benchmark). Based on Tableau’s R integration, Julia is a fantastic addition to Tableau’s Advanced Analytics stack and to your data science toolbox.

Where can I learn more?

Do you want to learn more about Advanced Analytics and how to leverage Tableau with R, Python and Julia? Meet me at the 2017 Tableau Conferences in London, Berlin or Las Vegas and join my Advanced Analytics sessions:

Will there be an online tutorial?

Yes, of course! I published tutorials for R and Python on this blog. And I will also publish a Julia tutorial soon. Feel free to follow me on Twitter @xlth, and leave me your feedback/suggestions in the comment section below.
