Data Demo – Using SQL in Python

sql database

Take your learning on the go during a practical data science demo with instructor Rich Ott. Often, the data we need is in a relational database that we can access with SQL. While it’s possible to use a separate utility to connect to the database and save the data to a file, we’ll want to […]

Data Demo – Python Optimization

man holding note for python

Take your learning on the go during a practical data science demo with instructor Ana Hocevar who will demonstrate optimization in Python. You’ll learn how to use Python’s SciPy library to find an optimum when we have a quantity we want to maximize (such as revenue) or minimize (some cost, an error rate, etc) while subject […]

GNU Make

gnu make

Learn some basics about GNU Make, which is a tool that controls the generation of executables and other non-source files of a program from the program’s source files. Make gets its knowledge of how to build your program from a file called the makefile, which lists each of the non-source files and how to compute […]

We’re back again with a new data demo to teach you some fundamental skills you can utilize on your journey as a data scientist (or data engineer). Maybe you’ve heard the term Web APIs in your research, but for those just starting out, Web APIs are a way of communicating and obtaining data from web-based […]

Linear Regression

linear regression

Linear regression is a commonly used technique, and parts of it are often justified by heuristics. In this video, we discuss the assumptions behind linear regression, and we show how it can be derived from statistical principles. We focus on the use of mean squared error as the error metric and regularization terms, showing how […]
