DyST: Towards Dynamic Neural Scene Representations on Real-World Videos

ICLR 2024spotlight

Visual understanding of the world goes beyond the semantics and flat structure of individual images. In this work, we aim to capture both the 3D structure and dynamics of real-world scenes from monocular real-world videos. Our Dynamic Scene Transformer (DyST) model leverages recent work in neural sc…

Moving Off-the-Grid: Scene-Grounded Video Representations

NeurIPS 2024spotlight

Current vision models typically maintain a fixed correspondence between their representation structure and image space. Each layer comprises a set of tokens arranged “on-the-grid,” which biases patches or tokens to encode information at a specific spatio(-temporal) location. In this work we present…

PaLM-E: An Embodied Multimodal Language Model

ICML 2023poster

Large language models excel at a wide range of complex tasks. However, enabling general inference in the real world, e.g. for robotics problems, raises the challenge of grounding. We propose embodied language models to directly incorporate real-world continuous sensor modalities into language models…

RUST: Latent Neural Scene Representations From Unposed Imagery

CVPR 2023highlight

Inferring the structure of 3D scenes from 2D observations is a fundamental challenge in computer vision. Recently popularized approaches based on neural scene representations have achieved tremendous impact and have been applied across a variety of applications. One of the major remaining challenges…

SlotFormer: Unsupervised Visual Dynamics Simulation with Object-Centric Models

ICLR 2023poster

Understanding dynamics from visual observations is a challenging problem that requires disentangling individual objects from the scene and learning their interactions. While recent object-centric models can successfully decompose a scene into objects, modeling their dynamics effectively still remain…

Conditional Object-Centric Learning from Video

ICLR 2022poster

Object-centric representations are a promising path toward more systematic generalization by providing flexible abstractions upon which compositional world models can be built. Recent work on simple 2D and 3D datasets has shown that models with object-centric inductive biases can learn to segment an…

Kubric: A Scalable Dataset Generator

CVPR 2022poster

Data is the driving force of machine learning, with the amount and quality of training data often being more important for the performance of a system than architecture and training details. But collecting, processing and annotating real data at scale is difficult, expensive, and frequently raises a…

Object Scene Representation Transformer

NeurIPS 2022accept

A compositional understanding of the world in terms of objects and their geometry in 3D space is considered a cornerstone of human cognition. Facilitating the learning of such a representation in neural networks holds promise for substantially improving labeled data efficiency. As a key step in this…

SAVi++: Towards End-to-End Object-Centric Learning from Real-World Videos

NeurIPS 2022accept

The visual world can be parsimoniously characterized in terms of distinct entities with sparse interactions. Discovering this compositional structure in dynamic visual scenes has proven challenging for end-to-end computer vision approaches unless explicit instance-level supervision is provided. Slot…

Scene Representation Transformer: Geometry-Free Novel View Synthesis Through Set-Latent Scene Representations

CVPR 2022poster

A classical problem in computer vision is to infer a 3D scene representation from few images that can be used to render novel views at interactive rates. Previous work focuses on reconstructing pre-defined 3D representations, e.g. textured meshes, or implicit representations, e.g. radiance fields, a…

Multi-Object Representation Learning with Iterative Variational Inference

ICML 2019oral

Human perception is structured around objects which form the basis for our higher-level cognition and impressive systematic generalization abilities. Yet most work on representation learning focuses on feature learning without even considering multiple objects, or treats segmentation as an (often su…

Relational Neural Expectation Maximization: Unsupervised Discovery of Objects and their Interactions

ICLR 2018poster

Common-sense physical reasoning is an essential ingredient for any intelligent agent operating in the real-world. For example, it can be used to simulate the environment, or to infer the state of parts of the world that are currently unobserved. In order to match real-world conditions this causal kn…

Highway and Residual Networks learn Unrolled Iterative Estimation

ICLR 2017poster

The past year saw the introduction of new architectures such as Highway networks and Residual networks which, for the first time, enabled the training of feedforward networks with dozens to hundreds of layers using simple gradient descent. While depth of representation has been posited as a primary…

Scalable Gradient-Based Tuning of Continuous Regularization Hyperparameters

ICML 2016poster

Hyperparameter selection generally relies on running multiple full training trials, with selection based on validation set performance. We propose a gradient-based approach for locally adjusting hyperparameters during training of the model. Hyperparameters are adjusted so as to make the model parame…

Tagger: Deep Unsupervised Perceptual Grouping

NeurIPS 2016poster

We present a framework for efficient perceptual inference that explicitly reasons about the segmentation of its inputs and features. Rather than being trained for any specific segmentation, our framework learns the grouping process in an unsupervised manner or alongside any supervised task. We enab…
