Semantic-enhanced Application Usage Prediction via Large Language Models

中文摘要英文摘要

应用使用预测是智能手机系统优化中的关键技术之一.本文提出一种基于大语言模型语义增强的预测方法,旨在提升模型对用户使用意图的理解能力与分布外泛化能力.通过引入大语言模型自动生成应用功能描述,并结合嵌入模型将文本描述编码为高维语义向量,作为用户历史使用序列的语义表征,输入下游任务模型进行预测.为了更有效地捕捉用户行为中的时序动态与语义依赖,本文设计了一种融合局部激活注意力机制与Mamba-2模块的预测模型.实验结果表明,在真实用户应用使用数据集上,该方法在分布内数据上Top-3准确率由76.41%提升至77.00%,在分布外数据上Top-3准确率由66.06%提升至71.57%,有效提升了模型对未见应用的泛化能力.

Application usage prediction is a crucial technique for optimizing smartphone systems.This study proposes a semantic-en-hanced prediction method based on large language models to improve the understanding of user intent and generalization to out-of-distribution applications.The method used a large language model to automatically generate functional descriptions of applications.These descriptions were encoded into high-dimensional semantic vectors through an embedding model and used as semantic repre-sentations of historical usage sequences.These representations were then fed into the prediction model.To better capture temporal dynamics and semantic dependencies in user behavior,a prediction model was designed by integrating locally activated attention mechanisms with a Mamba-2 module.Experimental results showed that on a real-world application usage dataset,the proposed method increased the Top-3 accuracy from 76.41%to 77.00%on in-distribution data and from 66.06%to 71.57%on out-of-distribu-tion data,significantly improving the model's generalization to unseen applications.
