Order-preserving Consistency Regularization for Domain Adaptation and Generalization

1 code implementation ICCV 2023 Mengmeng Jing, XianTong Zhen, Jingjing Li, Cees Snoek

To alleviate this problem, data augmentation coupled with consistency regularization are commonly adopted to make the model less sensitive to domain-specific attributes.

ProtoDiff: Learning to Learn Prototypical Networks by Task-Guided Diffusion

1 code implementation NeurIPS 2023 Yingjun Du, Zehao Xiao, Shengcai Liao, Cees Snoek

Furthermore, we introduce a task-guided diffusion process within the prototype space, enabling the meta-learning of a generative process that transitions from a vanilla prototype to an overfitted prototype.

Tubelet-Contrastive Self-Supervision for Video-Efficient Generalization

2 code implementations ICCV 2023 Fida Mohammad Thoker, Hazel Doughty, Cees Snoek

By simulating different tubelet motions and applying transformations, such as scaling and rotation, we introduce motion patterns beyond what is present in the pretraining data.

How Severe is Benchmark-Sensitivity in Video Self-Supervised Learning?

1 code implementation27 Mar 2022 Fida Mohammad Thoker, Hazel Doughty, Piyush Bagad, Cees Snoek

Despite the recent success of video self-supervised learning models, there is much still to be understood about their generalization capability.

Frequency-Supervised MR-to-CT Image Synthesis

1 code implementation19 Jul 2021 Zenglin Shi, Pascal Mettes, Guoyan Zheng, Cees Snoek

In this paper, we find that all existing approaches share a common limitation: reconstruction breaks down in and around the high-frequency parts of CT images.

Learning to Learn Kernels with Variational Random Features

1 code implementation ICML 2020 Xiantong Zhen, Haoliang Sun, Ying-Jun Du, Jun Xu, Yilong Yin, Ling Shao, Cees Snoek

We propose meta variational random features (MetaVRF) to learn adaptive kernels for the base-learner, which is developed in a latent variable model by treating the random feature basis as the latent variable.

The ActivityNet Large-Scale Activity Recognition Challenge 2018 Summary

no code implementations11 Aug 2018 Bernard Ghanem, Juan Carlos Niebles, Cees Snoek, Fabian Caba Heilbron, Humam Alwassel, Victor Escorcia, Ranjay Krishna, Shyamal Buch, Cuong Duc Dao

The guest tasks focused on complementary aspects of the activity recognition problem at large scale and involved three challenging and recently compiled datasets: the Kinetics-600 dataset from Google DeepMind, the AVA dataset from Berkeley and Google, and the Moments in Time dataset from MIT and IBM Research.

Guess Where? Actor-Supervision for Spatiotemporal Action Localization

2 code implementations5 Apr 2018 Victor Escorcia, Cuong D. Dao, Mihir Jain, Bernard Ghanem, Cees Snoek

Second, we propose an actor-based attention mechanism that enables the localization of the actions from action class labels and actor proposals and is end-to-end trainable.

Online Action Detection

no code implementations21 Apr 2016 Roeland De Geest, Efstratios Gavves, Amir Ghodrati, Zhenyang Li, Cees Snoek, Tinne Tuytelaars

Third, the start of the action is unknown, so it is unclear over what time window the information should be integrated.
