Titanic Data - Submission 5

Submission 5 (which I actually submitted on the same day as submission 4) has shown me a logical approach is worth pursuing.

I looked at my previous best submission, which used:

  1. gender
  2. pclass
  3. fare
  4. age - with survival coded as zero where age was missing.

With submission 5, I used a suggestion another competitor made on the forum, and used the title in the name to calculate an age.

This submission scored 0.77512, which was an improvement of 0.00957 over my previous score. I am now ranked 1068 out of 2449, and I improved 359 positions !!
