Data Description:

In this competition, you are going to predict the demographics of a user (gender and age) based on their app download and usage behaviors. 

The Data is collected from TalkingData SDK integrated within mobile apps TalkingData serves under the service term between TalkingData and mobile app developers. Full recognition and consent from individual user of those apps have been obtained, and appropriate anonymization have been performed to protect privacy. Due to confidentiality, we won't provide details on how the gender and age data was obtained. Please treat them as accurate ground truth for prediction. 

The data schema can be represented in the following chart:
