Since the 7.0 release of Alteryx, the number and breadth of predictive tools has expanded with each subsequent version, and the 8.5 release is no exception. At this point, there are three objectives that drive the development of the new predictive analytics capabilities in Alteryx:
The new tools in the 8.5 release, and some "under the hood" changes we have made to a number of the existing predictive analytics tools, all reflect one or more of these three objectives. In addition, we have made a number of changes in how we package predictive tools in Alteryx that will enable us to be more flexible and nimble in rolling out new capabilities by making the predictive toolkit a bit more independent from the Alteryx Designer Desktop release schedule, but, at the same time, we have better integrated the installation of Alteryx Predictive into the Designer Desktop installation process.
Five of the new predictive tools in 8.5 were added explicitly to improve data artisan productivity. Two of these tools were added to directly improve users' efficiency in undertaking common data preparation tasks for predictive analytics, and three to improve users efficiency in gaining an initial understanding of their data. The tools designed to improve data preparation efficiency are:
The new tools in 8.5 to help data artisans quickly gain an understanding of their data are:
The Alteryx 8.5 release contains a number of new tools for conducting particular types of predictive analytics analyses. In this release, we have put particular emphasis on tools for A/B testing and market basket analysis. The A/B testing tools assist users in conducting market experiments to look at the potential returns to new promotional programs, staffing changes, pricing changes, new marketing communications programs, store remodeling programs, and a large number of other business activities. The use of experiments allow an organization to "test drive" a potential action with a small sample of customers or locations before (potentially) rolling those changes out to all customers or locations. The market basket analysis tools allow an organization to explore patterns pertaining to what products and services customers tend to purchase together through the extraction of association rules and frequent itemsets from customer transaction data (the tools in this release consider only a single transaction at a time, but in the future we will be incorporating tools that look at patterns in the sequence of customer transactions). In upcoming blog posts and demonstration videos, I will cover the tools in these two areas in greater depth.
Another important addition is the introduction of a tool to estimate count data regression models, which are applicable in cases where the target field consists of an integer number of items (e.g., the number of visits a patient makes to a doctors office in a year or the number of phone numbers assigned to a mobile telephone account), outcomes that are not consistent with the assumptions of either linear or logistic regression models. A number of other tools have also been added that are used within the A/B testing tools, but are of value to data artisans as standalone tools, so have been added to the predictive analytics toolbox in Alteryx. The list of new tools in this area are:
Changes to improve the amount of data that can be analyzed using our R-based predictive analytic tools, and the speed of doing the needed analysis, have largely been done "under the hood." These changes have been done in two different ways. First, Alteryx Predictive in the 8.5 release makes use of the just released R version 3 engine. The primary goal of the R core team in the first release of the version 3 series is to significantly improve internal memory management and to increase the maximum size of the base unit (an R vector) that can be addressed. The second change we are implementing is increasing the percentage of the workload, and, in particular, data volumes that are handled by Alteryx as opposed to R. All of the new tools for the 8.5 release reflect this "Alteryx first" development philosophy, and many of the pre-8.5 release tools have been altered to reflect this philosophy as well. The changes in the existing tools have been carried out in way that won't break existing modules, macros, and analytic apps that you and your organization may have already developed.
This really constitutes our first steps in the area of speed and scaling. We are in the process putting together a set of relationships that will allow Alteryx Predictive to scale to any data size with increased speed. This process is well enough developed at this point that I can safely say we are planing on making a number of important announcements over the next couple of months in this area.
