Keeping it Fresh: Predict Restaurant Inspections
Goal of the Competition
The goal for this competition is to use data from social media to narrow the search for health code violations in Boston. Competitors will have access to historical hygiene violation records from the City of Boston — a leader in open government data — and Yelp's consumer reviews. The challenge: Figure out the words, phrases, ratings, and patterns that predict violations, to help public health inspectors do their job better.

Winning Submissions
| Place | Team or User | Score | Summary of Model |
|---|---|---|---|
| 1 | LilianaMedina | 0.8901 | I averaged the predictions of a random forest and a gradient boosted model. |
| 2 | qwang | 0.8931 | My approach was focused almost strictly on feature engineering. I used scikit-learn’s implementation of random forests in Python. |
| 3 | furiouseskimo | 0.9113 | I built four models for each target (random forest, extra random trees, gradient boosting machine, l2 logistic regression) and blended the predictions from these models to get my final submission. |
