LFG: A Generative Network for Real-Time Recommendation

1 code implementation31 Oct 2023 Junyi Liu

The recommendation model known as LFM (Latent Factor Model), which captures latent features through matrix factorization and gradient descent to fit user preferences, has given rise to various recommendation algorithms that bring new improvements in recommendation accuracy.

TCRA-LLM: Token Compression Retrieval Augmented Large Language Model for Inference Cost Reduction

no code implementations24 Oct 2023 Junyi Liu, Liangzhi Li, Tong Xiang, Bowen Wang, Yiming Qian

Our summarization compression can reduce 65% of the retrieval token size with further 0. 3% improvement on the accuracy; semantic compression provides a more flexible way to trade-off the token size with performance, for which we can reduce the token size by 20% with only 1. 6% of accuracy drop.

Data-driven Piecewise Affine Decision Rules for Stochastic Programming with Covariate Information

no code implementations26 Apr 2023 Yiyang Zhang, Junyi Liu, Xiaobo Zhao

Focusing on stochastic programming (SP) with covariate information, this paper proposes an empirical risk minimization (ERM) method embedded within a nonconvex piecewise affine decision rule (PADR), which aims to learn the direct mapping from features to optimal decisions.

CPS Attack Detection under Limited Local Information in Cyber Security: A Multi-node Multi-class Classification Ensemble Approach

no code implementations1 Sep 2022 Junyi Liu, Yifu Tang, Haimeng Zhao, Xieheng Wang, Fangyu Li, Jingyi Zhang

In order to train a global multi-class classifier without sharing the raw data across all nodes, the main result of our study is designing a multi-node multi-class classification ensemble approach.
