Progressive Feature Adjustment for Semi-supervised Learning from Pretrained Models

no code implementations9 Sep 2023 Hai-Ming Xu, Lingqiao Liu, Hao Chen, Ehsan Abbasnejad, Rafael Felix

As an effective way to alleviate the burden of data annotation, semi-supervised learning (SSL) provides an attractive solution due to its ability to leverage both labeled and unlabeled data to build a predictive model.

Instance-dependent Noisy-label Learning with Graphical Model Based Noise-rate Estimation

no code implementations31 May 2023 Arpit Garg, Cuong Nguyen, Rafael Felix, Thanh-Toan Do, Gustavo Carneiro

To address IDN, Label Noise Learning (LNL) incorporates a sample selection stage to differentiate clean and noisy-label samples.

PASS: Peer-Agreement based Sample Selection for training with Noisy Labels

no code implementations20 Mar 2023 Arpit Garg, Cuong Nguyen, Rafael Felix, Thanh-Toan Do, Gustavo Carneiro

The prevalence of noisy-label samples poses a significant challenge in deep learning, inducing overfitting effects.

Instance-Dependent Noisy Label Learning via Graphical Modelling

1 code implementation2 Sep 2022 Arpit Garg, Cuong Nguyen, Rafael Felix, Thanh-Toan Do, Gustavo Carneiro

Noisy labels are unavoidable yet troublesome in the ecosystem of deep learning because models can easily overfit them.

Generalised Zero-Shot Learning with Domain Classification in a Joint Semantic and Visual Space

no code implementations14 Aug 2019 Rafael Felix, Ben Harwood, Michele Sasdelli, Gustavo Carneiro

Most state-of-the-art GZSL approaches rely on a mapping between latent visual and semantic spaces without considering if a particular sample belongs to the set of seen or unseen classes.

Multi-modal Ensemble Classification for Generalized Zero Shot Learning

no code implementations15 Jan 2019 Rafael Felix, Michele Sasdelli, Ian Reid, Gustavo Carneiro

In this paper, we mitigate these issues by proposing a new GZSL method based on multi-modal training and testing processes, where the optimization explicitly promotes a balanced classification accuracy between seen and unseen classes.

Multi-modal Cycle-consistent Generalized Zero-Shot Learning

1 code implementation ECCV 2018 Rafael Felix, B. G. Vijay Kumar, Ian Reid, Gustavo Carneiro

In generalized zero shot learning (GZSL), the set of classes are split into seen and unseen classes, where training relies on the semantic features of the seen and unseen classes and the visual representations of only the seen classes, while testing uses the visual representations of the seen and unseen classes.
