With over 3 billion active social media users, establishing an active presence on social media networks is becoming increasingly essential in getting your business front of your ideal audience. These days, more and more consumers are looking to engage, connect and communicate with their favorite brands on social media.

Adding social media to your customer-centric data strategy will help boost brand awareness, increase followership, drive traffic to your website and generate leads for your sales funnel. In 2017, no organization should be without a plan that actively places their brand on social media, and analyzes their social media data.

Once you’ve started diving into social media analytics, how do you bring it to the next level? This session covers a customer-centric data strategy for scaling a social media data program.

Here are the links (i.e. additional resources) featured during the session to help you formulate your social media data program in order to build a stronger presence and retrieve powerful insights:

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.

Digitale Banken: Die Chancen von Blockchain, Künstlicher Intelligenz und Machine Learning

Die Zukunft im Finanzwesen bleibt vielversprechend und spannend. Haben uns kürzlich noch Innovationen in der Erschließung neuer Märkte und in der Vermögensverwaltung beschäftigt, so sind es heute mehr denn je die raffinierten datengetriebenen Technologien, die in den Vordergrund gerückt sind.

Anfang dieses Jahres startete Futura Analytics, ein Fintech, das enorme Datenmengen und maschinelle Lernmodelle nutzt, um Regeln zur Risikobewertung in Echtzeit umzuschreiben. Futura Analytics verwandelt Daten aus Twitter und anderen öffentlichen Quellen in nutzbare Signale und identifiziert die relevantesten Informationen in Echtzeit für Kunden im Finanzsektor (Beispiel: Bitcoin/Sentiment-Analyse).

Künstliche Intelligenz ist Teil der Zukunft

Banken und Fintechs nutzen die künstliche Intelligenz und die immer besser werdende Verarbeitung von natürlicher Sprache, um Kunden einen besseren Zugang zu Finanzdienstleistungen zu ermöglichen. Produktempfehlungen basierend auf Mustererkennung hilft die passende Dienstleistung anzubieten. Natürliche Sprache wird zu einer Vereinfachung von Zahlungsinteraktionen führen.

M2M-Lösungen rationalisieren Cloud-basierte Authentifizierung

Allerdings müssen Zahlungsinteraktionen direkt von Gerät zu Gerät immer noch Barrieren überwinden, wie z.B. das Gewährleisten einer nahtlose Authentifizierung zwischen den Endgeräten. Bis solche M2M-Lösungen (Machine-to-Machine) mit nahtloser Authentifizierung herstellerübergreifend verfügbar ist, werden sich Geräte weiterhin über Services in der Cloud authentifizieren, bevor Transaktionen ausgeführt werden.

Gamification schafft Anreize für mobile Bezahlung

Mobiles Bezahlen am Point-of-Sale haben sich noch immer nicht flächendeckend durchgesetzt. Obwohl Unternehmen in Zahlungsterminals bereitstellen, fehlt es an Anreizen, um die Nutzer dazu zu ermutigen, mit ihren mobilen Geräten zu bezahlen. Banken haben schon damit begonnen die kostenlose Bargeldversorgung einzuschränken. Fintechs können dem Handel mit Gamification helfen das mobile Zahlen für Kunden attraktiver machen.

Blockchain ermöglicht kostengünstige Transaktionsüberprüfung

Die Rolle der Blockchain-Technologie bei der Bereitstellung einer verteilten Transaktionshistorie weckt großes Interesse im Zahlungs- und Handelsökosystem. Die Technologie macht Transaktionsgebühren, die Anbieter wie PayPal für das Sicherstellen von Transaktionen erhoben haben, hinfällig. Die Nutzung der Blockchain zur kostengünstigen Überprüfung von Transaktionen wird bei Banken oben auf der Agenda stehen.

Maschinelles Lernen verbessert die Zahlungssicherheit

Durch die Digitalisierung von Zahlungen muss die Zahlungssicherheit über eine breite Palette an Endgeräten gewährleistet werden. Geräte können ein erhöhtes Risiko gegenüber fortgeschrittenen Angriffen aufweisen. Bei der Gestaltung von sicheren Zahlungsmethoden erkennt maschinelles Lernen das Verhalten und greift ein, wenn ein solches Verhalten auf ungewöhnliche Verhaltensweisen oder Transaktionsaktivitäten hindeutet.

Price and Sentiment Analysis: Why is Bitcoin Going Down?

Bitcoin has become one of the trendy investment assets in the recent years. Whenever bitcoin prices approach historical highs, every investor should watch the currency closely. Bitcoin rallied by more than 20% in the first days of 2017, crossing the $1000 mark for the first time since November 2013.

As many experienced bitcoin traders will remember, the first $1000 peak was a case of obvious over exuberance. Bitcoin was hot, plenty of money was pouring into it. Bitcoin investors got too excited, causing a price surge. Prices then rebounded and suffered a long-term collapse shortly after.

Moving Average Convergence/Divergence Indicator

Many traders rely on a Moving Average Convergence/Divergence (MACD) indicator. The MACD is a measure of the convergence and divergence between two EMAs (usually 12 and 26 days) and is calculated by subtracting the two of them. The signal line is constructed by creating an EMA (usually 10 days) of the signal line.

The signal line crossing the MACD from above is a buy signal. The signal line crossing the MACD from below is a sell signal. Relying only on momentum-based indicators (such as the MACD) and optimization-based models, however, will most certainly fail to indicate heavy price drops, as the drop in late 2016.

Predicting Fear with Sentiment Analysis

In late 2016 a lot of people began to pour money into bitcoin again. This time because they were worried that stock markets and other assets were due for a drop. For investors, it is essential to figure out whether or not these fears are actually founded. However, such “safe assets” are prone to suffering from bubbles. People get scared, get invested into gold, or bitcoin, then realize that their fears were unfounded. As a result bitcoin prices could plummet.

So how to catch emotions such as fear in advance? Twitter is a valuable source of information and emotion. It certainly influences the stock market and can help to predict the market. Sentiment analysis can lead price movements by up to two days. Negative sentiment, however, is reflected in the market much more than positive sentiment. This is probably because most people tweet positive things about bitcoins most of the time. Even more positive news occurred after breaking the $1000 barrier.
