In this paper, we explore the use of GAN-based few-shot data augmentation as a method to improve few-shot classification performance.  ...  We perform an exploration into how a GAN can be fine-tuned for such a task (one of which is in a class-incremental manner), as well as a rigorous empirical investigation into how well these models can  ...  In this paper we specifically focus on the data aspect of few-shot learning, which at its core leverages some form of data augmentation to augment a small set of examples into a much larger set, one that  ...

Conservative Generator, Progressive Discriminator: Coordination of Adversaries in Few-shot Incremental Image Synthesis [article]

Chaerin Kong, Nojun Kwak
2022 arXiv   pre-print
To effectively handle the inherent challenges of incremental learning and few-shot learning, we propose a novel framework named ConPro that leverages the two-player nature of GANs.  ...  Several works have previously explored incremental few-shot learning, a task with greater challenges due to data constraint, mostly in classification setting with mild success.  ...  As it differs from simple IL and few-shot learning, we propose a novel GAN framework named ConPro that collaborately addresses the challenges.  ...

Few-shot Image Generation with Mixup-based Distance Learning [article]

Chaerin Kong, Jeesoo Kim, Donghoon Han, Nojun Kwak
2022 arXiv   pre-print
In this work, we consider a challenging task of pretraining-free few-shot image synthesis, and seek to train existing generative models with minimal overfitting and mode collapse.  ...  GANs trained with limited data can easily memorize few training samples and display undesirable properties like "stairlike" latent space where interpolation in the latent space yields discontinuous transitions  ...  As naive training of GANs with small datasets often fails both in terms of fidelity and diversity, many have proposed novel approaches specifically designed for few-shot image synthesis.  ...

Generalized Few-Shot Video Classification with Video Retrieval and Feature Generation [article]

Yongqin Xian, Bruno Korbar, Matthijs Douze, Lorenzo Torresani, Bernt Schiele, Zeynep Akata
2021 arXiv   pre-print
Few-shot learning aims to recognize novel classes from a few examples. Although significant progress has been made in the image domain, few-shot video classification is relatively unexplored.  ...  Moreover, we find existing benchmarks are limited because they only focus on 5 novel classes in each testing episode and introduce more realistic benchmarks by involving more novel classes, i.e. few-shot  ...  In the few-shot learning stage, the same data augmentation is applied and the novel class classifier is learned with a constant learning rate 0.01 for 10 epochs on all the datasets.  ...

Few-Shot Learning with Intra-Class Knowledge Transfer [article]

Vivek Roy, Yan Xu, Yu-Xiong Wang, Kris Kitani, Ruslan Salakhutdinov, Martial Hebert
2020 arXiv   pre-print
Recent works have proposed to solve this task by augmenting the training data of the few-shot classes using generative models with the few-shot training samples as the seeds.  ...  However, due to the limited number of the few-shot seeds, the generated samples usually have small diversity, making it difficult to train a discriminative classifier for the few-shot classes.  ...  Second, we leverage the information transferred from many-shot classes to augment the sparse training data for few-shot classes using a meta-generator.  ...

Leveraging Local Domains for Image-to-Image Translation [article]

Anthony Dell'Eva, Fabio Pizzati, Massimo Bertozzi, Raoul de Charette
2022 arXiv   pre-print
Relying on a simple geometrical guidance, we train a patch-based GAN on few source data and hallucinate a new unseen domain which subsequently eases transfer learning to target.  ...  In this paper, we leverage human knowledge about spatial domain characteristics which we refer to as 'local domains' and demonstrate its benefit for image-to-image translation.  ...  An interesting characteristic of our method is that it trains few shots on source only, leveraging only minimal human knowledge about the target.  ...

F-VAEGAN-D2: A Feature Generating Framework for Any-Shot Learning

Yongqin Xian, Saurabh Sharma, Bernt Schiele, Zeynep Akata
2019 2019 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)  
In this paper, we tackle any-shot learning problems i.e. zero-shot and few-shot, in a unified feature generating framework that operates in both inductive and transductive learning settings.  ...  When labeled training data is scarce, a promising data augmentation approach is to generate visual features of unknown classes using their attributes.  ...  In contrast to those inductive approaches that only use labeled data from seen classes, transductive zero-shot learning methods additionally leverage unlabeled data from unseen classes.  ...
