This year we will focus on two particular tasks, Popularity Prediction and Tomorrow’s Top Prediction. Meanwhile, we are open for innovative self-proposed topics. The contestants are asked to develop their prediction algorithm based on the SMP dataset provided by the Challenge (as training data), plus possibly additional public/private data, to address one or both of the two given tasks (SMP-T1 or SMP-T2). For the evaluation purpose, a contesting system is asked to produce prediction results of popularity. The accuracy will be evaluated by pre-defined quantitative evaluation. The contestants need to introduce their algorithms and datasets in the conference.
