Dream2Real: Zero-Shot 3D Object Rearrangement with Vision-Language Models

no code implementations7 Dec 2023 Ivan Kapelyukh, Yifei Ren, Ignacio Alzugaray, Edward Johns

We introduce Dream2Real, a robotics framework which integrates vision-language models (VLMs) trained on 2D data into a 3D object rearrangement pipeline.

Learning Robust Kernel Ensembles with Kernel Average Pooling

no code implementations30 Sep 2022 Pouya Bashivan, Adam Ibrahim, Amirozhan Dehghani, Yifei Ren

Model ensembles have long been used in machine learning to reduce the variance in individual model predictions, making them more robust to input perturbations.

Visual-Inertial Multi-Instance Dynamic SLAM with Object-level Relocalisation

1 code implementation8 Aug 2022 Yifei Ren, Binbin Xu, Christopher L. Choi, Stefan Leutenegger

In this paper, we present a tightly-coupled visual-inertial object-level multi-instance dynamic SLAM system.

MULTIPAR: Supervised Irregular Tensor Factorization with Multi-task Learning

no code implementations1 Aug 2022 Yifei Ren, Jian Lou, Li Xiong, Joyce C Ho, Xiaoqian Jiang, Sivasubramanium Bhavani

By supervising the tensor factorization with downstream prediction tasks and leveraging information from multiple related predictive tasks, MULTIPAR can yield not only more meaningful phenotypes but also better predictive performance for downstream tasks.

Predictive Modeling with Delayed Information: a Case Study in E-commerce Transaction Fraud Control

no code implementations14 Nov 2018 Junxuan Li, Yung-wen Liu, Yuting Jia, Yifei Ren, Jay Nanduri

Using partially mature data directly for predictive modeling in an uncertain probabilistic decision environment would lead to significant inaccuracy on risk decision-making.
