Advanced Analytics With Tableau

In this session we are going to learn how to deploy connections between Tableau and its advanced analytics external services and then utilize these connections to develop powerful and flexible data science applications.

Automation And Augmentation

If you take a step back to consider the disruptive potential of AI, we believe there are two distinct and complementary opportunities.

The first opportunity is automation – this is taking the human out of the loop, and replacing them with an a model or algorithm that is more accurate, objective and efficient. Basically, any task that you have to repeat on a regular basis, where the considerations into the decisions are know and well-defined is a great candidate for this. 

The second opportunity is around augmentation, enhancing the human’s capacity to understand data to make better decisions with intelligent suggestions. 

Now this second opportunity, is the one that Tableau tends to focus on.  This stems from three main reasons:

  • The hardest decisions in businesses are the questions you only get to make a few times.  Those are made by humans.  For example, while you can automate the credit card pre-approval process, the decision of whether or not that process is worth automating, is human led decision, that is informed by data as well as the business context of the real world.
  • Predictions based on prior outcomes are not sufficient.  To make these decisions, you need to understand the underlying data generating process, because you are often seeking to change it, as part of the decision.
  • All of this requires human input, but as data grows, human resources are not growing with it.

Augmentation to amplify the human analyst is the solution.

Augmentation and Data Science at Tableau

So across Tableau, we have four major areas of investments we’re applying AI technologies on.  We’ll go through them one by one.

Democratizing Advanced Analytic

There is wide range of user for advanced analytic depends on the skillset of user as well as the use cases and the business problem need to be solved with advanced analytics.

Tableau ultimate goal is to democratize advanced analytic across this spectrum and provide a platform which can be used as enterprise standard. Saying that this wide range of advanced analytic users can be categorized into three main groups:

Analytic Extension API

What is tableau analytic extension api exactly? I am pretty sure almost everyone is familiar with or hear about dashboard extension which is the extension to put objects to dashboards everything from integrating more advanced analytics, natural language generation, database wrote back and many more. With analytic extension we will bring the same extended experience to tableau calculation.

What is TabPy?

The Analytics Extensions API (Previously, known as external services) was used originally for the Python integration with Tableau which allows users to call Python functions directly from Tableau. TabPy is a python open source library which expand tableau’s capability by allowing user to execute python code in Tableau.

Python Integration with Tableau

To the basic topology with Tableau desktop, tableau server or tableau prep builder we can configure a connection to the analytic extension meaning python pass data out and return back in the result.

In desktop and server it works through scrip calculation which has four type scrip Boolean, script integer, script real and script string and these are basically describing to tableau what to expect in the term of the type of returned data.
