04. Data Collection & Relevance Quiz

Data Collection

Say you are building a product that aims to recognize the make and model of a car (ex. Toyota Camry, 2001) in images of different streets and roads. How might you collect or create data that is useful for this task?

One of my favorite articles that involves detailed, car-data collection, is a paper by Timnit Gebru et al, about building a car dataset and using it to estimate the characteristics of certain geographical areas. Their method for data collection and creation (which uses a combination of approaches) is detailed in this appendix.

Data Relevance

Say you are building a customer experience bot that aims to group types of restaurant reviews. Your manager has asked you to flag common issues like cleanliness and service at different restaurants. What kind of data would be most relevant to this task?
SOLUTION: Text reviews sorted into specific complaint categories like hygiene, and service
