For February we turn our attention to time series & anomaly detection.

Please be sure to bring a government-issued photo ID that matches the name on your Meetup account. If you do not have a last name on your Meetup account we cannot guarantee you will be allowed in the building.

About the Talk:Data scientists & researchers are often tasked with measuring how a metric changes over time. Whether it's daily website visits, weekly sales, monthly unemployment rate, or annual population count, time series is one of the most commonly analyzed data formats across fields. This talk will demonstrate two statistical methods for approaching times series analysis, forecasting & anomaly detection, & when to apply them.

While forecasting allows us to predict future trends, anomaly detection helps us uncover irregularities in our data. We will draw upon real-life examples to explore different anomaly detection algorithms & illustrate how forecasting can help us identify seasonal trends & set targets for the future.

I will be introducing the following packages in R: Facebook's open-source forecasting package, prophet, Twitter's open-source AnomalyDetection, & its tidyverse counterpart, anomalize. Prior experience is not necessary & people of all levels are encouraged to attend.

About the Speaker:Catherine leads the data science team at Codecademy, where her research helps empower millions of users around the world to learn how to code. She has been working on statistical programming for the past decade. Prior to transitioning to a tech startup, she worked on airline ticket pricing & demand economics at JetBlue, subscription modeling at New York Sports Clubs, & various stints in politics, healthcare, & consulting. Before that, she was a bike mechanic.
