General In-Hand Object Rotation with Vision and Touch
Haozhi Qi, Brent Yi, Sudharshan Suresh +4
We introduce RotateIt, a system that enables fingertip-based object rotation along multiple axes by leveraging multimodal sensory inputs. Our system is trained in simulation, where…
Investigating the Catastrophic Forgetting in Multimodal Large Language Models
Yuexiang Zhai, Shengbang Tong, Xiao Li +4
Following the success of GPT4, there has been a surge in interest in multimodal large language model (MLLM) research. This line of research focuses on developing general-purpose LL…
Emergence of Segmentation with Minimalistic White-Box Transformers
Yaodong Yu, Tianzhe Chu, Shengbang Tong +4
Transformer-like models for vision tasks have recently proven effective for a wide range of downstream applications such as segmentation and detection. Previous works have shown th…
A Spatially Non-stationary Fading Channel Model for Simulation and (Semi-) Analytical Study of ELAA-MIMO
Jiuyu Liu, Yi Ma, Rahim Tafazolli
In this paper, a novel spatially non-stationary fading channel model is proposed for multiple-input multiple-output (MIMO) system with extremely-large aperture service-array (ELAA)…
On Chernoff Lower-Bound of Outage Threshold for Non-Central -Distributed MIMO Beamforming Gain
Jinfei Wang, Yi Ma, Rahim Tafazolli
The cumulative distribution function (CDF) of a non-central -distributed random variable (RV) is often used when measuring the outage probability of communication systems. For…
Alternative Normalized-Preconditioning for Scalable Iterative Large-MIMO Detection
Jiuyu Liu, Yi Ma, Rahim Tafazolli
Signal detection in large multiple-input multiple-output (large-MIMO) systems presents greater challenges compared to conventional massive-MIMO for two primary reasons. First, larg…
