In this meetup, Blair will give a quick introduction to online experimentation and A/B testing. To keep the tutorial self-contained, Blair will first give an overview of stats fundamentals needed to understand A/B testing and explain how A/B testing is done in an online business. In the end, Blair will cover some of the pitfalls […]
What is this Meetup about? How to automatically web scrape so you can analyze timely/frequently updated data. There are many blogs and tutorials that teach you how to scrape data from a bunch of web pages once and then you’re done. But one-off web scraping is not useful for many applications that require sentiment analysis […]
Come join Data Science Dojo for a community talk on Interactive Graphics with Shiny and Plotly! We can probably all recall a time in which we created a great chart and in the midst of discussion someone asks “What if…?” or “Why?”. Using conventional plotting libraries would require manual manipulation of the data or code […]

An unnecessary emphasis (admittedly, annoying to the speaker) on tools like R, Python, SparkML, and techniques like deep learning is prevalent. Relying on tools and techniques while ignoring the fundamentals is the wrong approach to model building. Real-world machine learning requires hard work, discipline and […]
“The universe is made of stories, not atoms.” —Muriel Rukeyser (1913–1980) Storytelling is a cornerstone of the human experience. Though many elements of stories have remained the same throughout history, we have developed better tools and mediums for telling them, such as printed books, movies, and comics. This has changed storytelling styles—and perhaps most importantly, […]
Business data presents a challenge for the data analyst. Business data is often aggregated, recorded over time, and tends to exhibit autocorrelation. Additionally, and most problematically, the amount of business data is usually quite limited. These characteristics lead to a situation where many of the tools in the analyst’s tool belt (e.g., regression) aren’t ideal […]
Meetup: YouTube’s #1 Data Scientist, David Langer, will show how easy it is to get started mining your event logs using the OSS tools of R and ProM. Event logs are everywhere and represent a prime source of Big Data. Event log sources run the gamut from e-commerce web servers to devices participating in globally […]
