FSDR: A Novel Deep Learning-based Feature Selection Algorithm for Pseudo Time-Series Data using Discrete Relaxation

no code implementations13 Mar 2024 Mohammad Rahman, Manzur Murshed, Shyh Wei Teng, Manoranjan Paul

Conventional feature selection algorithms applied to Pseudo Time-Series (PTS) data, which consists of observations arranged in sequential order without adhering to a conventional temporal dimension, often exhibit impractical computational complexities with high dimensional data.

Anti-aliasing Deep Image Classifiers using Novel Depth Adaptive Blurring and Activation Function

no code implementations3 Oct 2021 Md Tahmid Hossain, Shyh Wei Teng, Ferdous Sohel, Guojun Lu

In this work, first, we analyse deep features with Fourier transform and show that Depth Adaptive Blurring is more effective, as opposed to monotonic blurring.

A novel network training approach for open set image recognition

no code implementations27 Sep 2021 Md Tahmid Hossaina, Shyh Wei Teng, Guojun Lu, Ferdous Sohel

Convolutional Neural Networks (CNNs) are commonly designed for closed set arrangements, where test instances only belong to some "Known Known" (KK) classes used in training.

Integrated Generalized Zero-Shot Learning for Fine-Grained Classification

no code implementations31 Dec 2020 Tasfia Shermin, Shyh Wei Teng, Ferdous Sohel, Manzur Murshed, Guojun Lu

In this paper, we propose to explore global and direct attribute-supervised local visual features for both EL and FS categories in an integrated manner for fine-grained GZSL.

Bidirectional Mapping Coupled GAN for Generalized Zero-Shot Learning

no code implementations30 Dec 2020 Tasfia Shermin, Shyh Wei Teng, Ferdous Sohel, Manzur Murshed, Guojun Lu

Bidirectional mapping-based generalized zero-shot learning (GZSL) methods rely on the quality of synthesized features to recognize seen and unseen data.

Adversarial Network with Multiple Classifiers for Open Set Domain Adaptation

no code implementations1 Jul 2020 Tasfia Shermin, Guojun Lu, Shyh Wei Teng, Manzur Murshed, Ferdous Sohel

The proposed multi-classifier structure introduces a weighting module that evaluates distinctive domain characteristics for assigning the target samples with weights which are more representative to whether they are likely to belong to the known and unknown classes to encourage positive transfers during adversarial training and simultaneously reduces the domain gap between the shared classes of the source and target domains.

Enhanced Transfer Learning with ImageNet Trained Classification Layer

no code implementations25 Mar 2019 Tasfia Shermin, Shyh Wei Teng, Manzur Murshed, Guojun Lu, Ferdous Sohel, Manoranjan Paul

Thus, we hypothesize that the presence of this layer is crucial for growing network depth to adapt better to a new task.

Transfer Learning Using Classification Layer Features of CNN

no code implementations19 Nov 2018 Tasfia Shermin, Manzur Murshed, Guojun Lu, Shyh Wei Teng

Although CNNs have gained the ability to transfer learned knowledge from source task to target task by virtue of large annotated datasets but consume huge processing time to fine-tune without GPU.

Distortion Robust Image Classification using Deep Convolutional Neural Network with Discrete Cosine Transform

no code implementations14 Nov 2018 Md Tahmid Hossain, Shyh Wei Teng, Dengsheng Zhang, Suryani Lim, Guojun Lu

Experimental results demonstrate that once trained, DCT-Net not only generalizes well to a variety of unseen image distortions but also outperforms other methods in the literature.
