Are you participating in AXA and's latest challenge? If so, find out how Data Science Studio can help you out.

The Challenge

To start off 2015 with a fun data challenge, AXA and recently launched "Building a cross-selling affinity score for an insurance product during a telemarketing campaign." The contest, which is composed of two distinct phases, challenges participants to score insurance products for cross-sales. The prizes range from €5000 (first place) to €500 (6th place).

  • At the end of the first phase (january 5, 2015 - march 6, 2015), a quantitative metric (minimum of 10% lift) will determine the 6 best contributors.
  • In the second phase (march 9, 2015 - march 27, 2015), the 6 participants will replicate their project in Dataiku's Data Science Studio. Based on these results, a jury composed of experts and of an AXA judge will classify the finalists and deliver prizes accordingly.

In this blog post, you’ll find a few tips and tricks on how to properly use Data Science Studio for the challenge.

In the model bench, you can try different algorithms and compare them to each other. In this example, we are testing Logistic Regression (L1 penalty, C=0.15), Logistic Regression (L2 penalty, C=0.15), and a Random Forest:
