Poll: What Predictive Analytics, Data Mining, Data Science software/tools you used in the past 12 months?

Vote in KDnuggets 16th Annual Poll: What Analytics, Data Mining, Data Science software/tools you used in the past 12 months for a real project?. We will clean and analyze the results and publish our trend analysis afterwards.

By Gregory Piatetsky, @kdnuggets.

One of the longest KDnuggets traditions is our annual Data Mining (aka Analytics, aka Data Science) software poll.

Here is my post with poll results and analysis:
R leads RapidMiner, Python catches up, Big Data tools grow, Spark ignites

The state of analytics industry constantly changes. We started with the companies in Gartner Magic Quadrant(tm) for Advanced Analytics and Forrester Wave(tm) for Big Data Predictive Analytics , and added companies/tools from last year poll, added relevant new ones, while trying to keep the total number still manageable ( under 100).

This is the 16th such KDnuggets Poll, and it usually attracts a lot of attention and sometimes controversy due to excessive voting by some vendors. It is fine to ask your users to vote, but it is not OK to set up bot voting or direct link to vote for just one tool. To reduce excessive and bot voting, this poll asks for email verification.

Whatever other irregular voting we find, will be removed from final results, and we will publish the anonymized voter logs after the poll, so that anyone can analyze them.

We hope our analysis of this poll, trends, and results will useful, as they were in the past.

Data Mining Tools Here is our analysis of KDnuggets 2014 Annual Software Poll.

This year, we removed the division between commercial and free tools, since many tools have both a free and paid version and it is difficult to have separate votes for those.

Note that there are 4 categories in this poll: Platforms/Suite, Languages, Deep Learning Tools (new), and Hadoop-based tools.
