Preview of What We’ll Build

Today we’re going to build dashboards using a little bit of everything including Python-based tools and Microsoft’s Power BI.

But before we get to building our dashboards, we’re also going to build a REST API data source with Django that uses a machine-learning algorithm to classify sentiment from human-written…

Our group’s assigned task involved coming up with an app that would recommend no copyright…


Today’s post will deal with what may be one of the hardest aspects of data science which doesn’t involve analysis, but simply trying to make the backend of data science work. By backend I mean the database systems most data scientists will be working with on the job.

I will…


It’s been 9 weeks since I’ve started learning data science from Lambda School. The challenge this week involves a multi-class classification problem presented as a Kaggle competition involving just the students in our class: DS-1.

Our task is to predict which water pumps in Tanzania are faulty with a combination…


Which would you have invested in?

The fundamental reason why we visualize things in Data Science isn’t just to show off pretty pictures, but to express ideas that do not lend themselves to easy comprehension.
