Researchers have developed STAP, a novel Transformer-based model designed for predicting the next mobile application a user will launch. Unlike existing methods that rely on fixed app vocabularies, STAP uses a shuffle-tokenization mechanism to assign random virtual indices to app identities, thereby eliminating the need for a predefined vocabulary. This approach, combined with an ultra-long context design, allows STAP to generalize across different app ecosystems and perform effectively in zero-shot and cold-start scenarios. Experiments show STAP achieves strong cross-dataset prediction accuracy and competitive within-dataset performance, with a deployment strategy to manage latency. AI
