Sample This: Sampling Randomly from the Streets

Say you want to learn about the average number of potholes per unit paved street in a city. To estimate that quantity, the following sampling plan can be employed: 1. Get all the streets in a city from Google Maps or OSM 2. Starting from one end of the street,

Clustering and then Classifying: Improving Prediction for Crudely-labeled and Mislabeled Data

Mislabeled and crudely labeled data are common problems in data science. Supervised prediction of such data is expectedly to yield poor results—coefficients are biased, and accuracy with regard to the true label is poor. One solution to the problem is to hand-code labels of an `adequate’ sample and infer
