Developing natural speech recognition and speech synthesis systems requires speech data that authentically represents real emotions. However, this type of data is often challenging to obtain. Machine speech chain offers a solution to this challenge by using unpaired data to continue training models initially trained with paired data. Given the relative abundance of unpaired data compared to paired data, machine speech chain can be instrumental in recognizing emotions in speech where training data is limited. This study investigates the application of machine speech chain in speech emotion recognition and speech recognition of emotional speech. Our findings indicate that a model trained with 50% paired neutral emotion speech data and 22% paired non-neutral emotional speech data shows a reduction in Character Error Rate (CER) from 37.55% to 34.52% when further trained with unpaired neutral emotion speech data. The CER further decreases to 33.75% when additionally trained with combined unpaired speech data. The accuracy of recognizing non-neutral emotions ranged from 2.18% to 53.51 %, though the F1 score fluctuated, increasing by up to 20.6% and decreasing by up to 23.4%. These results suggest that the model demonstrates a bias towards the majority class, as reflected by the values of the two metrics. © 2024 IEEE.

The development of IoT has increased the demand to use IoT devices for indoors and outdoors. IoT devices need to reduce power consumption because batteries power them. Conventional methods are that IoT devices split data and transfer it to neighboring devices to reduce power consumption. One of the reasons for increased power consumption in IoT devices is to activate the Wi-Fi module. This paper reduces the number of IoT devices that activate the Wi-Fi module and prolongs the total operating time of IoT devices. The proposed method determines the IoT device that activates the Wi-Fi module by Clustering and Weighting. Clustering means that the server creates groups for IoT devices. The element of the cluster is the IoT device to which the neighbor IoT device one hop forward is connected. Weighting means that the IoT device sets its weight as a unique indicator. The IoT device with an activated Wi-Fi module has the most remaining battery power and the highest weight value. The experiment compares the operation time of IoT devices with the proposed method, which distributes the data transmitted by IoT devices to neighboring devices. The experimental results were 521 [min] for the proposed method and 456 [min] for the existing method, which is prolonged 14.2 [%]. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Relaxation through a natural environment in virtual worlds is proposed for easily experiencing forest-bathing. However, creating the virtual worlds requires costs such as the time to create and technical capabilities. In this study, we compare the relaxation effects of experiencing natural environments using three types of media: a 360-degree video, a 360-degree image, and virtual reality. The purpose is to explore methods for making mental health care with a VR device more accessible. In our approach, we measure stress levels by experiencing natural environments using a VR device by five indicators: electroencephalogram (EEG), heart rate, salivary amylase, the State- Trait Anxiety Inventory (STAI), and a subjective stress questionnaire. As a result, no significant differences were found in the relaxation effects of different media for all indicators. The result suggests that the 360-degree video and the 360-degree image, which can be created at a lower cost, may have almost the same relaxation effect as virtual reality. © 2023 IEEE.

Road damage detection (RDD) through computer vision and deep learning techniques can ensure the safety of vehicles and humans on the roads. Integrating unmanned aerial vehicles (UAVs) in RDD and infrastructure evaluation (IE) has also emerged as a key enabler, contributing significantly to data acquisition and real-time monitoring of road damages, such as potholes, cracks, and surface anomalies, facilitating proactive maintenance and improved road conditions. These UAVs are low-powered and resource-constrained devices that work autonomously to perform pattern detection and decision making leveraging tiny machine learning (Tiny ML) algorithms. These Tiny ML algorithms are designed to run on edge devices, IoT devices, UAVs, etc. In this study, the RDD2022 data set collected using UAVs and dashboard cameras of vehicles was utilized to train pure and mixed models that exhibit class instance imbalance in certain classes which is addressed by implementing data augmentation as a regularization technique. State-of-the-art two-stage detectors: Faster R-CNN ResNet101 and one-stage detectors: SSD MobileNet V1 FPN, YOLOv5, and Efficientdet D1 are employed. The results indicate that the two-stage detector achieved an impressive mean average precision (mAP) of 88.49% overall and 96.62% for focused classes. Notably, the state-of-the-art Efficientdet D1 approach achieved a competitive mAP of 86.47% overall and 95.12% for focused classes, with significantly lower computational cost. These findings highlight the potential of advanced object detection techniques, particularly Efficientdet D1, to enhance the accuracy and efficiency of RDD systems, thereby improving passenger safety and overall performance. © 2014 IEEE.

Acquiring purpose-specific data is crucial for applying deep learning to applications. However, creating such data can be labor-intensive, necessitating the development of datasets at minimal cost. Consequently, there has been a recent trend towards utilizing computer-generated imagery (CGI) to generate purpose-specific datasets. Nonetheless, models trained on CGI data often exhibit suboptimal performance on real images due to domain gap issues. Thus, bridging this gap between synthetic and real data domains is crucial. We are developing a real parts classification application using 3D CAD models as training data. This study discusses our strategies for addressing the domain gap challenge in this application. To mitigate this gap, we explore three primary approaches: selecting architectures with a strong shape bias, leveraging large-scale pre-training to enhance generalization performance, and enhancing the shape bias of classifiers by manipulating color characteristics in the training data. We present evidence demonstrating the effectiveness of these meth-ods in bridging the domain gap between CG I training data and real-world images in our part classification application: the top-l accuracy became 98.34 % at the best case. © 2024 IEEE.

The escalating visibility of secure direct object reference (IDOR) vulnerabilities in API security, as indicated in the compilation of OWASP Top 10 API Security Risks, highlights a noteworthy peril to sensitive data. This study explores IDOR vulnerabilities found within Android APIs, intending to clarify their inception while evaluating their implications for application security. This study combined the qualitative and quantitative approaches. Insights were obtained from an actual penetration test on an Android app into the primary reasons for IDOR vulnerabilities, underscoring insufficient input validation and weak authorization methods. We stress the frequent occurrence of IDOR vulnerabilities in the OWASP Top 10 API vulnerability list, highlighting the necessity to prioritize them in security evaluations. There are mitigation recommendations available for developers, which recognize its limitations involving a possibly small and homogeneous selection of tested Android applications, the testing environment that could cause some inaccuracies, and the impact of time constraints. Additionally, the study noted insufficient threat modeling and root cause analysis, affecting its generalizability and real-world relevance. However, comprehending and controlling IDOR dangers can enhance Android API security, protect user data, and bolster application resilience. © 2023 IEEE.

computer-aided Medical Image Segmentation (MIS) plays a leading role in diagnosing diseases automatically. MIS is used extensively in diagnosing medical ailments to obtain clinically relevant information of the shapes and volumes of the target organs and tissues. In order to facilitate accurate segmentation, a Block Attention Based Deep Residual Neural Network, i.e., CBAR-UNet model, is proposed to perform cardiac image segmentation on short axis Magnetic Resonance Images (MRI) stacks from top to bottom slice. The Automated Cardiac Diagnosis Challenge (ACDC) dataset is used in the proposed work, which comprise of a 3D MRI of 100 patients (i.e., 200 MRI stacks). Further, 3D MRIs are converted into 2D by slicing each image to train the model, and Contrast Limited Adaptive Histogram Equalization (CLAHE) is performed on the 2D dataset. Residual connections are introduced that aid in training deeper models. Convolutional Block Attention Module (CBAM) is also added in the proposed network, which consists of Spatial and Channel attention that enhances the spatial and channel-wise features in the image by providing information like ‘what’ and ‘where’ to pay attention respectively. To test and validate the proposed methodology, extensive experimentations were conducted and it was observed that proposed image segmentation model delivers better results by 2.47% when compared to both 2D and 3D State-Of-The-Art (SOTA) methods with a Dice Score of 0.9428. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.

A Novel Design of Random Number Generators Using Chaos-Based Extremum Coding

IEEE Access 2024年 12卷 24039-24047页

This paper proposes a new chaos-based extremum coding method to realize a true random number generator (RNG). Based on the chain rule, we innovatively introduce two parameters into the dynamics of chaotic systems to modulate the speed and amplitude of state responses. Then, by discretizing the continuous modulated chaotic system, the corresponding discrete chaotic system can be obtained, which allows the use of low-cost micro-controllers for implementation, enhancing system stability, and reducing costs. Also, a novel chaos-based extremum coding approach is proposed for generating a random extremum-coded sequence (RECS). Using this RECS to switch and decide modulation parameters significantly improves the randomness of the sequences generated by the RNGs. To highlight the contribution of this RNG design, the randomness and security of the RNGs are evaluated by statistical tests such as NIST, Diehard, and ENT. Through comparisons with recent published works, the results show that the proposed chaotic extremum-coded RNG can demonstrate superior performance with a higher level of randomness. © 2013 IEEE.
