Competitive Collaboration: Joint Unsupervised Learning of Depth, Camera Motion, Optical Flow and Motion Segmentation

1 code implementation CVPR 2019 Anurag Ranjan, Varun Jampani, Lukas Balles, Kihwan Kim, Deqing Sun, Jonas Wulff, Michael J. Black

We address the unsupervised learning of several interconnected problems in low-level vision: single view depth prediction, camera motion estimation, optical flow, and segmentation of a video into the static scene and moving regions.

Learning to See by Looking at Noise

1 code implementation NeurIPS 2021 Manel Baradad, Jonas Wulff, Tongzhou Wang, Phillip Isola, Antonio Torralba

We investigate a suite of image generation models that produce images from simple random processes.

Procedural Image Programs for Representation Learning

1 code implementation29 Nov 2022 Manel Baradad, Chun-Fu Chen, Jonas Wulff, Tongzhou Wang, Rogerio Feris, Antonio Torralba, Phillip Isola

Learning image representations using synthetic data allows training neural networks without some of the concerns associated with real images, such as privacy and bias.

Optical Flow in Mostly Rigid Scenes

no code implementations CVPR 2017 Jonas Wulff, Laura Sevilla-Lara, Michael J. Black

Existing algorithms typically focus on either recovering motion and structure under the assumption of a purely static world or optical flow for general unconstrained scenes.

Efficient Sparse-to-Dense Optical Flow Estimation Using a Learned Basis and Layers

no code implementations CVPR 2015 Jonas Wulff, Michael J. Black

Given a set of sparse matches, we regress to dense optical flow using a learned set of full-frame basis flow fields.

Improving Inversion and Generation Diversity in StyleGAN using a Gaussianized Latent Space

no code implementations14 Sep 2020 Jonas Wulff, Antonio Torralba

We show that, under a simple nonlinear operation, the data distribution can be modeled as Gaussian and therefore expressed using sufficient statistics.

Do We Still Need Clinical Language Models?

no code implementations16 Feb 2023 Eric Lehman, Evan Hernandez, Diwakar Mahajan, Jonas Wulff, Micah J. Smith, Zachary Ziegler, Daniel Nadler, Peter Szolovits, Alistair Johnson, Emily Alsentzer

To investigate this question, we conduct an extensive empirical analysis of 12 language models, ranging from 220M to 175B parameters, measuring their performance on 3 different clinical tasks that test their ability to parse and reason over electronic health records.
