With the rising prominence of gold as a lucrative investment avenue in Iran, this research delves into predicting the future price of 18-carat gold. In pursuit of this objective, a comprehensive comparison is conducted between two neural network architectures: the Gated Recurrent Unit (GRU) as a single structure and a hybrid model combining Convolutional Neural Network (CNN) and Long Short-Term Memory Neural Network (LSTM). The evaluation criteria employed focus on error metrics to gauge the accuracy of price predictions. Results reveal that the CNN-LSTM hybrid neural network exhibits superior performance, showcasing lower error values in predicting the price of 18-carat gold in Iran. Consequently, the chosen model, CNN-LSTM, is employed to forecast the following day's gold prices, providing valuable insights for investors navigating the Iranian market. This research contributes to the ongoing discourse on gold investment strategies by highlighting the effectiveness of advanced neural network models in enhancing predictive accuracy. © 2024 IEEE.

As cryptocurrencies become more popular as investment vehicles, bitcoin draws interest from businesses, consumers, and computer scientists all across the world. Bitcoin is a computer file stored in digital wallet applications where each transaction is secured using strong cryptographic algorithms. It was challenging to forecast the future price of bitcoin due to its nonlinearity and extreme volatility. Several recent classic parametric models have been found with limited accuracy. To address the limitations and fill the existing research gaps, there is a need for a good prediction model which will provide the desired accuracy in the case of uncertainty and dynamism. This research suggested a deep learning-based framework for predicting and forecasting Bitcoin price. The research will be helpful for worldwide consumers and industries to take their decision on whether to invest or not. The research utilizes Yahoo! finance dataset for the period of 01-03-2016 to 26-02-2021 having 1828 samples. The experimental outcomes of the proposed Long Short-Term Memory (LSTM) model outperformed similar deep learning models by securing minimum loss and confirming that it can be used for future price prediction of the cryptocurrencies, which is helpful for the buyer to take their decision. © 1975-2011 IEEE.

Early fire Due to the small target and the occurrence of early scene complexity, the existing fire detection methods make it very easy to miss the detection of false detection phenomena. To address the above problems, this study designs CAC-Net, a fire detection method based on residual feature extraction and a self-attention mechanism. The method utilizes an efficient two-step residual feature extraction module to finely tune the receptive field and enhance the extraction of complex features as well as small object features. Effective Pyramid Aggregation Module AF accurately aggregates task-related information. The CGD module uses group convolution and techniques to efficiently arrange convolution filters for efficient flow and integration of information between different feature map channels, achieving lower false detections. In this paper, we conduct detailed and rich experiments on a live-collected dataset and achieve 96.4% precision and 96.1% recall. The experimental results demonstrate that the CAC-Net model significantly reduces the misdetection and omission of fires and has efficient research value in the task of early fire detection in complex scenarios. © 2024 SPIE.

Osteoarthritis is a disorder that transpires when the articular cartilage in the knee breaks down and changes to the underbelly of the cartilage. Normal joint fracture protection for the bones is provided by the slick substance known as articular cartilage. Early prediction can slow down the progression of the condition. Medical professionals' expertise is utilized to predict severity. In this research, we address the issue that arises when a model's validation accuracy is lower than its training accuracy. Specifically, we find that as dataset size increases, the validation accuracy of Osteoarthritis prediction falls. We used a Deep Convolutional Neural Network to develop an automatic osteoarthritis severity assessment system using the Kellgren and Lawrence (KL) grading system. With this method, X-ray images are used to predict the severity of osteoarthritis. This study's objective is to predict the severity stage of knee osteoarthritis in the form of prediction accuracy (in %) of osteoarthritis using a transfer learning and deep learning approach. As a result, EfficientNetB5 provides a prediction accuracy of over 97.45% as demonstrated in this work. © 2024 IEEE.

Heterogeneous information alignment and re-ranking for cross-modal pedestrian re-identification

引用

Multimedia Tools and Applications 2024年 1-24页

作者： Zhao, Tiezhu Liang, Xiaolun He, Kejing Yang, Qiuhong Ren, Ziliang School of Computer Science and Technology Dongguan University of Technology Guangdong Dongguan523808 China School of Computer Science and Engineering South China University of Technology Guangdong Guangzhou510641 China School of Artificial Intelligence and mathematical Dongguan City University Guangdong Dongguan523419 China

Cross-modal pedestrian re-identification, encompassing visible and infrared images, presents a significant challenge owing to inherent disparities in imaging principles, resulting in substantial cross-modal discrepancies. Consequently, matching and extracting heterogeneous information becomes exceedingly arduous. To address these issues, this research introduces a novel cross-modal pedestrian re-identification methodology, leveraging a heterogeneous information alignment algorithm and a reranking strategy. Specifically, a novel algorithm for aligning heterogeneous local information is proposed, which dynamically aligns the diverse local details of a given pedestrian by identifying the shortest path within the distance matrix of the pedestrian’s heterogeneous local information. Furthermore, to tackle the predicament of extracting heterogeneous pedestrian information, an expanded k-nearest neighbor reranking strategy is introduced, which integrates the heterogeneous information of the same pedestrian by dynamically developing the k-nearest neighbor heterogeneous information derived from the query image. Extensive experimental evaluations substantiate the effectiveness of the proposed approach across diverse scenarios. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.
