What you'll learn

  • Learn how Uber applies recurrent neural networks to time series analysis


Time series forecasting and anomaly detection is of utmost importance at Uber. However, the scale of the problem, the need for speed, and the importance of accuracy make anomaly detection a challenging data science problem. Andrea Pasqua and Anny Chen explain how the use of recurrent neural networks is allowing Uber to meet this challenge.

Topics include:

  • Why time series are of great importance at Uber
  • The business implication of accurate and reliable forecasting
  • The need for a platform solution for anomaly detection
  • The methodology used
  • The results
  • Future developments
