Meetup Summary – Winning Data Science Competitions

If you’ve never heard of kaggle, I guess the first question I have to ask is “how did you end up on DataScience.LA?” 🙂

Kaggle is one of the foremost machine learning competition websites on the internet. Companies from GE to Criteo and everything in between create competitions. These competitions are in the form of a dataset, ranging from small to relatively large (up to many many gigabytes), a stated goal (such as predicting an event or finding a numeric value) and an evaluation criteria. The Kaggle community has grown in the last few years, so that now competitions often host thousands of participants!

On October 27th, we were fortunate to have Jeong-Yoon Lee, Chief Data Scientist at Conversion Logic and Kaggle master, present to the DataScience.LA Data Science meetup. His presentation covered a wide range of topics, from the dynamics of team building on Kaggle, through advanced techniques such as how the winning team for the latest competition ensembled 64 different models to get their winning solution.

Check out his slides below, and his video above! It was a fantastic meetup and a great way to cap off the DataScience.LA 2015 Data Science meetup season. We hope to see more of you in 2016, hopefully not just in the audience, but on the podium speaking! The community works better when everyone contributes.

We were very fortunate to have two members of the community shoot video for this event! If the above video from Jeff Weakley doesn’t show up, please try this alternate video from DSLA community member Carl Mullins.
