Waveform Design for Joint Communication and SAR Imaging Under Random Signaling

no code implementations26 Mar 2024 Bowen Zheng, Fan Liu

Conventional synthetic aperture radar (SAR) imaging systems typically employ deterministic signal designs, which lack the capability to convey communication information and are thus not suitable for integrated sensing and communication (ISAC) scenarios.

A Large Language Model Enhanced Sequential Recommender for Joint Video and Comment Recommendation

1 code implementation20 Mar 2024 Bowen Zheng, Zihan Lin, Enze Liu, Chen Yang, Enyang Bai, Cheng Ling, Wayne Xin Zhao, Ji-Rong Wen

Meanwhile, we leverage the LLM recommender as a supplemental component (discarded in deployment) to better capture underlying user preferences from heterogeneous interaction behaviors.

Parallel Algorithms for Exact Enumeration of Deep Neural Network Activation Regions

no code implementations29 Feb 2024 Sabrina Drammis, Bowen Zheng, Karthik Srinivasan, Robert C. Berwick, Nancy A. Lynch, Robert Ajemian

Our work has three main contributions: (1) we present a novel algorithm framework and parallel algorithms for region enumeration; (2) we implement one of our algorithms on a variety of network architectures and experimentally show how the number of regions dictates runtime; and (3) we show, using our algorithm's output, how the dimension of a region's affine transformation impacts further partitioning of the region by deeper layers.

Adapting Large Language Models by Integrating Collaborative Semantics for Recommendation

1 code implementation15 Nov 2023 Bowen Zheng, Yupeng Hou, Hongyu Lu, Yu Chen, Wayne Xin Zhao, Ming Chen, Ji-Rong Wen

To address this challenge, in this paper, we propose a new LLM-based recommendation model called LC-Rec, which can better integrate language and collaborative semantics for recommender systems.

Rethinking Population-assisted Off-policy Reinforcement Learning

no code implementations4 May 2023 Bowen Zheng, Ran Cheng

In this paper, we first analyze the use of off-policy RL algorithms in combination with population-based algorithms, showing that the use of population data could introduce an overlooked error and harm performance.

TAE: A Semi-supervised Controllable Behavior-aware Trajectory Generator and Predictor

no code implementations2 Mar 2022 Ruochen Jiao, Xiangguo Liu, Bowen Zheng, Dave Liang, Qi Zhu

Our model addresses trajectory generation and prediction in a unified architecture and benefits both tasks: the model can generate diverse, controllable and realistic trajectories to enhance planner optimization in safety-critical and long-tailed scenarios, and it can provide prediction of critical behavior in addition to the final trajectories for decision making.
