Interview with Tim Schwuchow, Data Science Lead at Premise Data
We thank Tim Schwuchow from Premise Data for taking part in the part of the Data Science Interview Series 2020 .
How did you first get into data science?
I’m a reformed academic. I spent too much in grad school and did coding projects on my own and loved doing my own statistical analysis. I fell in love with it and then got involved with Premise.
We’ve been doing crazy, exciting things and I’m lucky to have a lot of autonomy. I have a lot of trust and power and am allowed to find ways to make the data useful. I’ve been really blessed to have opps here to make our data valuable for our customers. It’s like we have eyes everywhere in the world and are able to assemble what we see into meaning. The challenge is to render the information in a way that is useful for decision makers. I feel like there is so much we can say and do here….we have the right data and culture.
How is data science used to create value in your current project(s)?
One of the projects we’re working on at the moment is a project called Iris. It’s a UI and backend system for taking the data we collect about places and aggregating it into a foundational layer about points of interest around the world.
For example, we take individual submissions from tasks completed by our crowdsourcing network (of two million contributors from around the world) which might be something like, “Go to any bank, take a pic of the sign and tell us what it’s like to be there. What are the hours? What services are available?” We ask different questions in different places. The individual views are interesting but we want to build a consensus. We want to group the data and say, “This group of data pertain to this place and this set pertains to a different place.”
What are the key skills that you use every day as a data scientist, and how did you develop them?
Apart from programming, having some domain knowledge of statistics and economics has been extremely helpful in my current role. Another project I’ve been working on at Premise is the processing of the data that we collect about the prices of various goods into consumer prices indices; knowledge of time series econometrics is obviously very important for that!
