Many things, such as goods, products, and websites are evaluated based on user's notes and comments. One popular research project is sentiment analysis, which aims to extract information from notes and comments as a natural language processing (NLP) to understand and express emotions. In this study we analyzed the sentiment of ChatGPT labeled tweet datasets sourced from the Kaggle community using five Machine Learning (ML) algorithms;decision tree, KNN, Naïve Bayes, Logistic Regression, and SVM. We applied three feature extraction techniques: positive/negative frequency, a bag of words (count vector), and TF IDF. For each classification algorithm. The results were assessed using accuracy measures. Our experiments achieved an accuracy of 96.41% with the SVM classifier when using TF- IDF as a feature extraction technique. © 2024 Slovene Society Informatika. All rights reserved.

Image forgery is the alteration of a digital image to hide some of the important and useful information. Copy-move forgery (CMF) is one of the most difficult to detect because the copied part of the image has the same characteristics as the original image. Most of the existing datasets only highlight additional attacks in the copied part. Since there are no categories of duplication elements in the datasets, this research analyzed three categories of duplication elements in CMF which are animals, food and non-living things using DEFACTO and CoMo3Dataset. The analysis is performed on PatchMatch-based detection method and the results show that the method able to maintain at least 83% for all duplication elements in both DEFACTO and CoMo3Dataset. Furthermore, the method is able to detect a minimum 92% score for the food category in both datasets. © 2023 IEEE.

In the digital era, people use e-mail as the primary means of communication, as well as credentials and private communication in their work. Sending fake e-mails is usually illegal and aims to steal data or implant malware. Fake e-mails must be prevented and detected as early as possible. This paper proposes a new model for detecting fake e-mail-sending activities using a machine learning classifier approach: NaÏve Bayes, k-NN and Decision Tree. The aim is to see the performance of several classification methods and analyze the best detection performance from using classification methods. This paper contributed to introducing a new extracting features technique and modelling it as a detection model using a machine learning approach. The experiment shows that the decision tree model can detect optimally with an accuracy value of 98.11%, precision of 94.04%, and recall of 99.93%. This model can help system administrators handle appropriate procedures. © 2024 IEEE.

The rapid growth of cryptocurrencies has gained much attention by media, investors and scholars, since it is widely used for investment purposes as an alternative to regular currencies. Therefore the intelligent management and under-standing the characteristics of cryptocurrencies are becoming more interesting. The price of cryptocurrencies are characterized by linear and nonlinear trend, seasonality and high volatility, which increases the risk factors for investors. This study ex-periments with three different time series forecasting methods, specifically considered for Cryptocurrencies price such as Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Monero (XMR) and Cardano (XRP), and devises a procedure to evaluate their performance. Time series data are collected and examined using descriptive statistics. In next step, the White Neural Network is used for Non-Linearity and Dickey-Fuller for nonstationary and correlation among different settings of datasets. Based on these analyses, we evaluate efficient financial forecasting models such as Autoregressive Integrated Moving Average (ARIMA), Trigonometric, Box-Cox transformation, ARMA errors, Trend and Seasonal (TBATS) and Neural Network Autoregressive (NNAR) with reference to different parameters configuration of these models. The performance is evaluated using Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE) criterion and models are ranked by statistical mean and standard deviation of MAPE values. The NNAR model gives minimum MAPE of 2.823 while the minimum convergence time of 4.9835s is observed with TBATS and hence, these are ranked at top amongst other models respectively. These results underpin that neural network-based models perform equally well on both types of nonlinear and linear financial data and, thus, have the potential to improve the impact of financial transaction and cryptocurrencies price bringing more innovation in the decision making process. © 2022 IEEE.

A crucial role in the BRT transportation system's planning, development, and operation is the prediction of passenger numbers. Using time-series data, it is necessary to develop careful prediction models, appropriate techniques, and an indepth understanding of the number of BRT Transjakarta passengers. A prediction model is sought based on comparing combined LSTM and BiLSTM experiments using three evaluation matrices and time. Historical data used from daily passenger data for 13 BRT Transjakarta corridors (1/01/2021-31/12/2023). The best prediction model was obtained from the BiLSTM-CNN combination with the lowest MSLE (0.0425), MAPE (0.1598), and SMAPE (15.9387) evaluation matrix values. However, it required a longer time (00:02:14). Predictions of passenger numbers on the 13 Transjakarta BRT corridors for the next 12 months can be made simultaneously by predicting fluctuations occurring simultaneously. The strongest positive correlation is in corridor 9-6, while the strongest negative correlation is in corridor 12-5. The prediction results must be understood by stakeholders, managers, and technopreneurs to develop and support appropriate strategies to increase the number of BRT passengers. © 2024 IEEE.

A neural network approach is presented to solve the delay constraint and loss data multicast routing problem, an NP-complete problem. The multicast tree is obtained in line with optimal (minimum) routing costs which are subjected to integrated delay and loss data constraints. The proposed routing algorithm is designed to find the optimal (shortest) path taking into account traffic conditions (the incoming traffic flow, routers occupancy, and link capacities), avoiding packet loss data to the input buffer overflow and combine them into the union. The experimental results showed that the proposed method using the discrete-Time equation has achieved a significant difference in iterations and execution time compared to other proposals such as Runge-Kutta, Euler equations, ant colony algorithm and Hierarchical Hopfield neural network which contributes to improving the performance of Internet of Things networks in terms of the durability of interconnection between devices. In accordance with the extent of the impact of quality of service restrictions on the network, and the maintenance of the cost-effectiveness of the route, the algorithm achieved a decrease in execution time ranging from 27% to 81%, in addition to a decrease in the number of iterations by 44% to 66%. © 2022 ACM.
