Pre-Training LiDAR-Based 3D Object Detectors Through Colorization

1 code implementation23 Oct 2023 Tai-Yu Pan, Chenyang Ma, Tianle Chen, Cheng Perng Phoo, Katie Z Luo, Yurong You, Mark Campbell, Kilian Q. Weinberger, Bharath Hariharan, Wei-Lun Chao

Accurate 3D object detection and understanding for self-driving cars heavily relies on LiDAR point clouds, necessitating large amounts of labeled data to train.

Emergent Correspondence from Image Diffusion

1 code implementation NeurIPS 2023 Luming Tang, Menglin Jia, Qianqian Wang, Cheng Perng Phoo, Bharath Hariharan

We propose a simple strategy to extract this implicit knowledge out of diffusion networks as image features, namely DIffusion FeaTures (DIFT), and use them to establish correspondences between real images.

Distilling from Similar Tasks for Transfer Learning on a Budget

1 code implementation ICCV 2023 Kenneth Borup, Cheng Perng Phoo, Bharath Hariharan

To alleviate this, we propose a weighted multi-source distillation method to distill multiple source models trained on different domains weighted by their relevance for the target task into a single efficient model (named DistillWeighted).

Unsupervised Adaptation from Repeated Traversals for Autonomous Driving

1 code implementation27 Mar 2023 Yurong You, Cheng Perng Phoo, Katie Z Luo, Travis Zhang, Wei-Lun Chao, Bharath Hariharan, Mark Campbell, Kilian Q. Weinberger

For a self-driving car to operate reliably, its perceptual system must generalize to the end-user's environment -- ideally without additional annotation efforts.

A theoretically grounded characterization of feature representations

no code implementations29 Sep 2021 Bharath Hariharan, Cheng Perng Phoo

We present theoretical results showing how these measurements can be used to bound the error of the downstream classifiers, and show empirically that these bounds correlate well with actual downstream performance.

Coarsely-Labeled Data for Better Few-Shot Transfer

1 code implementation ICCV 2021 Cheng Perng Phoo, Bharath Hariharan

Few-shot learning is based on the premise that labels are expensive, especially when they are fine-grained and require expertise.
