Uncertainty Estimation for 3D Object Detection via Evidential Learning

no code implementations31 Oct 2024 Nikita Durasov, Rafid Mahmood, Jiwoong Choi, Marc T. Law, James Lucas, Pascal Fua, Jose M. Alvarez

We introduce a framework for quantifying uncertainty in 3D object detection by leveraging an evidential learning loss on Bird's Eye View representations in the 3D detector.

Neural Spacetimes for DAG Representation Learning

no code implementations25 Aug 2024 Haitz Sáez de Ocáriz Borde, Anastasis Kratsios, Marc T. Law, Xiaowen Dong, Michael Bronstein

NSTs are implemented as three neural networks trained in an end-to-end manner: an embedding network, which learns to optimize the location of nodes as events in the spacetime manifold, and two other networks that optimize the space and time geometries in parallel, which we call a neural (quasi-)metric and a neural partial order, respectively.

Approximation Rates and VC-Dimension Bounds for (P)ReLU MLP Mixture of Experts

no code implementations5 Feb 2024 Anastasis Kratsios, Haitz Sáez de Ocáriz Borde, Takashi Furuya, Marc T. Law

Mixture-of-Experts (MoEs) can scale up beyond traditional deep learning models by employing a routing strategy in which each input is processed by a single "expert" deep learning model.

Graph Metanetworks for Processing Diverse Neural Architectures

no code implementations7 Dec 2023 Derek Lim, Haggai Maron, Marc T. Law, Jonathan Lorraine, James Lucas

However, those works developed architectures tailored to specific networks such as MLPs and CNNs without normalization layers, and generalizing such architectures to other types of networks can be challenging.

Bridging the Sim2Real gap with CARE: Supervised Detection Adaptation with Conditional Alignment and Reweighting

no code implementations9 Feb 2023 Viraj Prabhu, David Acuna, Andrew Liao, Rafid Mahmood, Marc T. Law, Judy Hoffman, Sanja Fidler, James Lucas

Sim2Real domain adaptation (DA) research focuses on the constrained setting of adapting from a labeled synthetic source domain to an unlabeled or sparsely labeled real target domain.

Optimizing Data Collection for Machine Learning

no code implementations3 Oct 2022 Rafid Mahmood, James Lucas, Jose M. Alvarez, Sanja Fidler, Marc T. Law

Modern deep learning systems require huge data sets to achieve impressive performance, but there is little guidance on how much or what kind of data to collect.

f-Domain-Adversarial Learning: Theory and Algorithms

1 code implementation21 Jun 2021 David Acuna, Guojun Zhang, Marc T. Law, Sanja Fidler

Unsupervised domain adaptation is used in many machine learning applications where, during training, a model has access to unlabeled data in the target domain, and a related labeled dataset.

Low Budget Active Learning via Wasserstein Distance: An Integer Programming Approach

no code implementations5 Jun 2021 Rafid Mahmood, Sanja Fidler, Marc T. Law

Active learning is the process of training a model with limited labeled data by selecting a core subset of an unlabeled data pool to label.

Self-Supervised Real-to-Sim Scene Generation

no code implementations ICCV 2021 Aayush Prakash, Shoubhik Debnath, Jean-Francois Lafleche, Eric Cameracci, Gavriel State, Stan Birchfield, Marc T. Law

Synthetic data is emerging as a promising solution to the scalability issue of supervised deep learning, especially when real data are difficult to acquire or hard to annotate.

Ultrahyperbolic Representation Learning

1 code implementation NeurIPS 2020 Marc T. Law, Jos Stam

In machine learning, data is usually represented in a (flat) Euclidean space where distances between points are along straight lines.

Video Face Clustering with Unknown Number of Clusters

1 code implementation ICCV 2019 Makarand Tapaswi, Marc T. Law, Sanja Fidler

Understanding videos such as TV series and movies requires analyzing who the characters are and what they are doing.

Deep Spectral Clustering Learning

no code implementations ICML 2017 Marc T. Law, Raquel Urtasun, Richard S. Zemel

We derive a closed-form expression for the gradient that is efficient to compute: the complexity to compute the gradient is linear in the size of the training mini-batch and quadratic in the representation dimensionality.

Closed-Form Training of Mahalanobis Distance for Supervised Clustering

no code implementations CVPR 2016 Marc T. Law, Yao-Liang Yu, Matthieu Cord, Eric P. Xing

Clustering is the task of grouping a set of objects so that objects in the same cluster are more similar to each other than to those in other clusters.
