A stable deep adversarial learning approach for geological facies generation

The simulation of geological facies in an unobservable volume is essential in various geoscience applications. Given the complexity of the problem, deep generative learning is a promising approach to overcome the limitations of traditional geostatistical simulation models, in particular their lack of physical realism. This research aims to investigate the application of generative adversarial networks and deep variational inference for conditionally simulating channelized reservoir in underground volumes. In this paper, we review the generative deep learning approaches, in particular the adversarial ones and the stabilization techniques that aim to facilitate their training. We also study the problem of conditioning deep learning models to observations through a variational Bayes approach, comparing a conditional neural network model to a Gaussian mixture model. The proposed approach is tested on 2D and 3D simulations generated by the stochastic process-based model Flumy. Morphological metrics are utilized to compare our proposed method with earlier iterations of generative adversarial networks. The results indicate that by utilizing recent stabilization techniques, generative adversarial networks can efficiently sample complex target data distributions.

A review of the applications of generative adversarial networks to structural and functional MRI based diagnostic classification of brain disorders.

Structural and functional MRI (magnetic resonance imaging) based diagnostic classification using machine learning has long held promise, but there are many roadblocks to achieving their potential. While traditional machine learning models suffered from their inability to capture the complex non-linear mapping, deep learning models tend to overfit the model. This is because there is data scarcity and imbalanced classes in neuroimaging; it is expensive to acquire data from human subjects and even more so in clinical populations. Due to their ability to augment data by learning underlying distributions, generative adversarial networks (GAN) provide a potential solution to this problem. Here, we provide a methodological primer on GANs and review the applications of GANs to classification of mental health disorders from neuroimaging data such as functional MRI and showcase the progress made thus far. We also highlight gaps in methodology as well as interpretability that are yet to be addressed. This provides directions about how the field can move forward. We suggest that since there are a range of methodological choices available to users, it is critical for users to interact with method developers so that the latter can tailor their development according to the users' needs. The field can be enriched by such synthesis between method developers and users in neuroimaging.

Water depth prediction in combined sewer networks, application of generative adversarial networks

This paper addresses the pressing issue of combined sewer overflows (CSOs) in urban areas, which pose significant environmental and public health threats. CSOs occur when combined sewer systems become overwhelmed during heavy rainfall, leading to untreated sewage and stormwater being discharged into nearby water bodies. To effectively manage and mitigate CSO effects, accurate predictions of CSOs are crucial for real-time control measures. This study introduces an innovative approach that utilizes Generative Adversarial Networks (GANs) to augment data and improve the accuracy of data-driven models for predicting water depth in combined sewer systems. Apart from data augmentation, the paper addresses scenarios where rare patterns, such as extreme events, are infrequently observed regardless of dataset size. It proposes a specialized generative model based on GANs designed to augment datasets targeting these rare patterns. This innovation involves adding a tail-focused loss function to the adversarial objective of the GAN training pipeline. The research is exemplified through a case study in Kaiserslautern, Germany. The results indicate an improvement in water depth predictions. Also, it was found that the model trained solely with synthetic data is comparable to that trained with real data.Graphical

Application of Generative Adversarial Network in Image Color Correction

The popularity of electronic products has increased with the development of technology. Electronic devices allow people to obtain information through the transmission of images. However, color distortion can occur during the transmission process, which may hinder the usefulness of the images. To this end, a deep residual network and a deep convolutional network were used to define the generator and discriminator. Then, self-attention-enhanced convolution was applied to the generator network to construct an image resolution correction model based on coupled generative adversarial networks. On this basis, a generative network model integrating multi-scale features and contextual attention mechanism was constructed to achieve image restoration. Finally, performance and image restoration application tests were conducted on the constructed model. The test showed that when the coupled generative adversarial network was tested on the Set5 dataset, the image peak signal-to-noise ratio and image structure similarity values were 31.2575 and 0.8173. On the Set14 dataset, they were 30.8521 and 0.8079, respectively. The multi-scale feature-fusion algorithm was tested on the BSDS100 dataset with an image peak signal-to-noise ratio of 30.2541 and an image structure similarity value of 0.8352. Based on the data presented, it can be concluded that the image correction model constructed in this study has a strong image restoration ability. The reconstructed image has the highest similarity with the real high-resolution image and a low distortion rate. It can achieve the task of repairing problems such as color distortion during image transmission. In addition, this study can provide technical support for similar information correction and restoration work.

Attention-guided generator with dual discriminator GAN for real-time video anomaly detection

Detecting anomalies in videos presents a significant challenge in the field of video surveillance. The primary goal is identifying and detecting uncommon actions or events within a video sequence. The difficulty arises from the limited availability of video frames depicting anomalies and the ambiguous definition of anomaly. Based on extensive applications of Generative Adversarial Networks (GANs), which consist of a generator and a discriminator network, we propose an Attention-guided Generator with Dual Discriminator GAN (A2D-GAN) for real-time video anomaly detection (VAD). The generator network uses an encoder–decoder architecture with a multi-stage self-attention added to the encoder and multi-stage channel attention added to the decoder. The framework uses adversarial learning from noise and video frame reconstruction to enhance the generalization of the generator network. Also, of the dual discriminator in A2D-GAN, one discriminates between the reconstructed video frame and the real video frame, while the other discriminates between the reconstructed noise and the real noise. Exhaustive experiments and ablation studies on four benchmark video anomaly datasets, namely UCSD Peds, CUHK Avenue, ShanghaiTech, and Subway, demonstrate the effectiveness of the proposed A2D-GAN compared to other state-of-the-art methods. The proposed A2D-GAN model is robust and can detect anomalies in videos in real-time. The source code to replicate the results of the proposed A2D-GAN model is available at https://github.com/Rituraj-ksi/A2D-GAN.

AbstractConcentric tube continuum robots are a promising type of robot for various medical applications. Their application in neurosurgery poses challenging requirements for design and control that can be addressed by physics‐informed data‐based approaches. A prerequisite to data‐based modeling is an informative, rich data set. However, limited access to experimental data raises interest in partially or entirely synthetic data sets. In this contribution, we study the application of generative adversarial networks (GANs) for data augmentation in a data‐based design process of such robots.

Bi2O2Se-Based Bimode Noise Generator for the Application of Generative Adversarial Networks.

In the emerging technology, the generative aversive networks (GANs), randomness, and unpredictability of inputting noises are the keys to the uniqueness, diversity, robustness, and security of the generated images. Compared with deterministic software-based noise generation, hardware-based noise generation introduces physical entropy sources, such as electronic and photonic noises, to add unpredictability. In this study, bimode Bi2O2Se-based noise generators have been demonstrated for the application of GANs. Harnessing its ultrahigh carrier mobility, excellent air stability, marvelous optoelectronic performance, as well as the unique surface resistive switching effect and defect locations in the energy diagram, Bi2O2Se provides a good material platform to easily integrate with multiple device architectures for generating noises in different physical sources. The noise of the black current mode in a photodetector architecture and the random telegraph noise in a memristor mode were measured, characterized, compared, and analyzed. A method of Markov chain equipped with K-means clustering was carried out to calculate the discrete noise states and the transition probability matrix between them. To evaluate the generated properties of the GANs based on the hardware noise source, the inception score and Fréchet inception distance were evaluated.

A review of few-shot image recognition using semantic information

In recent years, the utilization of deep learning techniques has been employed in the field of image recognition with the aim of improving performance. However, deep learning demands a substantial amount of labeled data for model training, a process that is both expensive and time-consuming. In order to tackle this particular difficulty, the approach of few-shot learning (FSL) has emerged as a viable alternative. FSL, or Few-Shot Learning, is a computational approach that aims to replicate the cognitive processes observed in humans. By using a small set of examples and experiences, FSL enables the acquisition of new concepts. Research in the field of FSL has investigated many approaches to extracting the highest amount of information from limited data or making use of affordable and easily accessible sources of information. Researchers have been incorporating outside data into FSL techniques more frequently. This paper conducts an in-depth exploration of leveraging semantic information to enhance few-shot learning. By reviewing papers from the last five years in WOS, IEEE, and Science Direct (some papers in arXiv are also used), this study delves into the strategies employed to bridge the gap between visual and semantic information. The review extends to encompass zero-shot learning, which is considered a subcategory of FSL, enriching the analysis. Moreover, this paper identifies the potential of employing semantic information to enhance fine-grained few-shot (FGFS) learning. Techniques such as direct projection and the application of generative adversarial networks (GANs) emerge as promising avenues to accomplish this enhancement.
