Prolog: Introducing data artist Noah

Step 1: Understand How to Succeed with Social Media

Apple has officially joined Instagram on 7th August 2017. This isn’t your average corporate account as the company doesn’t want to showcase its own products. Instead, Apple is going to share photos shot with an iPhone:

The Customer-Centric Data Strategy

Apple’s Instagram account is more an extension of the “Shot on iPhone” billboard ad campaign.

And there are plenty takeaways for every business:

  • Wrap your data around your customers, in order to create business value
  • Interact with your customer in a natural way
  • Understand your customer and customer behaviour better by analyzing social media data

Step 2: Define Your Social Objectives and KPIs

A previous record-holding tweet: In 2014, actor and talk show host Ellen DeGeneres took a selfie with a gaggle of celebrities while hosting the Oscars. That photo has 3.44 million retweets at the time of writing:

Social Objectives:

  • Define specific KPIs for social media platforms
  • KPI objectives need to be measurable
  • Metrics should be in line with the business goals

Step 3: Assemble Your KPIs

Brand Awareness and Reputation

Step 4: Connect Your Social Media with Tableau

Option 1 – Directly from the platform: Get data directly from Facebook, Twitter, YouTube, and more

Option 2 – Via web automation: Use a service like IFTTT to store data on Google Sheets

Option 3 – Via web data connector: Use Tableau’s web data connector, e.g. the Twitter Web Data Connector by Alex Ross (a.k.a. Tableau Junkie) -> http://bit.ly/tc18_twitter

Option 4 – Code your own solution: Use an API provided by the platform -> http://bit.ly/tc17_r_fetch

Option 5 – Via a third party platform: Get data from an integrated social media platform, such as Talkwalker -> http://bit.ly/tc17_talkwalker

Talkwalker - Via a Third Party Platform

Step 5: Apply some Tips to Level Up

Gather Historic Data

Step 6: Explore Social Media Listening

Social listening means that you look beyond your own content. E.g. Talkwalker offers AI for image recognition and ggregation for online/offline media: http://bit.ly/tc17_talkwalker

Step 7: Leverage Your Analytics Tool Chain

Use Your R and Python Skills

Digitale Banken: Welche Digitalisierungstrends bewegen die Finanzbranche 2018?

Immersive und interaktive Analyse von Finanzdaten mit Argumented Reality
Immersive und interaktive Analyse von Finanzdaten mit Argumented Reality (Blockchain-Dashboard)

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:
