Dear Colleagues 

We are delighted to announce that there will be a time series anomaly detection contest under the auspices of ACM SIGKDD 2021. 

The contest will provide 200 time series datasets, divided into a train phase, and a test phase. The task is to build a model on the train phase, and predict the location of the single anomaly in the test phase.
We hope to encourage the development of general-purpose time series anomaly detection algorithms, thus the test datasets come from various domains, medicine, industry, science, human behavior, animal behavior etc.   

First Prize: $2000 USD
Second Prize: $1000 USD
Third Prize: $500 USD

For the top 15 participants we will provide a certificate with rank, for all other participants will get a participation certificate.

Happy hunting, the team.
