Chicago Food Inspection Forecasting21 Feb 2017
One of the biggest challenges The City of Chicago - Department of Public Health faces is keeping up with the the sheer volume of food establishments across the city that require sanitation inspection. The goal is to make that inspection prior to critical health violations.
There are just three dozen inspectors responsible for inspecting these 15,000 establishments on regular basis, amounting to ~420 establishments per person. Given the large number of inspections to be completed, the time and effort it takes to discover critical violations can mean prolonged exposure to potential disease, illness, and unsanitary conditions at some food establishments. This necessitates identifying of establishments that could likely be making a critical violation and the number of days before an inspection has to be made in those establishments.
The data for this forecast is taken from The City of Chicago’s GitHub location. On top of the basic models provided by them, I developed Logitic Regression, XGBoost, Extra Trees, and GBM predictive models. Using ShinyApps I created visuals to show the performance of each model and the number of days before an establishment has to be inspected.
