On Modulating the Gradient for Meta-Learning

1 code implementation ECCV 2020 Christian Simon, Piotr Koniusz, Richard Nock, Mehrtash Harandi

Inspired by optimization techniques, we propose a novel meta-learning algorithm with gradient modulation to encourage fast-adaptation of neural networks in the absence of abundant data.

Hyper-VolTran: Fast and Generalizable One-Shot Image to 3D Object Structure via HyperNetworks

no code implementations24 Dec 2023 Christian Simon, Sen He, Juan-Manuel Perez-Rua, Mengmeng Xu, Amine Benhalloum, Tao Xiang

Solving image-to-3D from a single view is an ill-posed problem, and current neural reconstruction methods addressing it through diffusion models still rely on scene-specific optimization, constraining their generalization capability.

On Manipulating Scene Text in the Wild with Diffusion Models

no code implementations1 Nov 2023 Joshua Santoso, Christian Simon, Williem Pao

In experiments, we thoroughly assess and compare our proposed method against state-of-the-arts on various scene text datasets, then provide extensive ablation studies for each granularity to analyze our performance gain.

FLATTEN: optical FLow-guided ATTENtion for consistent text-to-video editing

no code implementations9 Oct 2023 Yuren Cong, Mengmeng Xu, Christian Simon, Shoufa Chen, Jiawei Ren, Yanping Xie, Juan-Manuel Perez-Rua, Bodo Rosenhahn, Tao Xiang, Sen He

In this paper, for the first time, we introduce optical flow into the attention module in the diffusion model's U-Net to address the inconsistency issue for text-to-video editing.

Subspace Distillation for Continual Learning

no code implementations31 Jul 2023 Kaushik Roy, Christian Simon, Peyman Moghadam, Mehrtash Harandi

To mitigate forgetting prior knowledge, we propose a novel knowledge distillation technique that takes into the account the manifold structure of the latent/output space of a neural network in learning novel tasks.

On Generalizing Beyond Domains in Cross-Domain Continual Learning

no code implementations CVPR 2022 Christian Simon, Masoud Faraki, Yi-Hsuan Tsai, Xiang Yu, Samuel Schulter, Yumin Suh, Mehrtash Harandi, Manmohan Chandraker

Humans have the ability to accumulate knowledge of new tasks in varying conditions, but deep neural networks often suffer from catastrophic forgetting of previously learned knowledge after learning a new task.

Dialog+ in Broadcasting: First Field Tests Using Deep-Learning-Based Dialogue Enhancement

no code implementations17 Dec 2021 Matteo Torcoli, Christian Simon, Jouni Paulus, Davide Straninger, Alfred Riedel, Volker Koch, Stefan Wits, Daniela Rieger, Harald Fuchs, Christian Uhle, Stefan Meltzer, Adrian Murtaza

To address this, Fraunhofer IIS has developed a deep-learning solution called Dialog+, capable of enabling speech level personalization also for content with only the final audio tracks available.

Meta-Learning for Multi-Label Few-Shot Classification

no code implementations26 Oct 2021 Christian Simon, Piotr Koniusz, Mehrtash Harandi

Even with the luxury of having abundant data, multi-label classification is widely known to be a challenging task to address.

Towards a Robust Differentiable Architecture Search under Label Noise

no code implementations23 Oct 2021 Christian Simon, Piotr Koniusz, Lars Petersson, Yan Han, Mehrtash Harandi

Our empirical evaluations show that the noise injecting operation does not degrade the performance of the NAS algorithm if the data is indeed clean.

On Learning the Geodesic Path for Incremental Learning

1 code implementation CVPR 2021 Christian Simon, Piotr Koniusz, Mehrtash Harandi

This in practice is done by minimizing the dissimilarity between current and previous responses of the network one way or another.

Reinforced Attention for Few-Shot Learning and Beyond

no code implementations CVPR 2021 Jie Hong, Pengfei Fang, Weihao Li, Tong Zhang, Christian Simon, Mehrtash Harandi, Lars Petersson

Few-shot learning aims to correctly recognize query samples from unseen classes given a limited number of support samples, often by relying on global embeddings of images.

Projective Subspace Networks For Few-Shot Learning

no code implementations ICLR 2019 Christian Simon, Piotr Koniusz, Mehrtash Harandi

Generalization from limited examples, usually studied under the umbrella of meta-learning, equips learning techniques with the ability to adapt quickly in dynamical environments and proves to be an essential aspect of lifelong learning.
