So, emotion recognition uses the network containing each wave to become relevant. EEG signals record electrical activity in the brain from several channels. Therefore, EEG signal processing needs consideration to spatial and temporal. Spatial is a signal between channels, while temporal is a sequence. Several methods were used, Convolutional Neural Networks (CNN) with various dimensions, Recurrent Neural Networks (RNN), and hybrid CNN-RNN. This paper proposed a hybrid 2D CNN-RNN method for identifying emotions from a parallel network of each wave. Two-dimensional CNN is used in channel extraction in a short time of the signal. Using short-time signals is intended to minimize the non-stationary characteristic of EEG signals. Meanwhile, the identification of emotions is carried out with RNN using the output of 2D CNN extraction. The modeling and testing used a dataset from SEED, with three emotion classes: positive, neutral, and negative. The experimental results show that using a split network of each wave increased accuracy from 80.92% to 84.71% and a decreased Loss value. While the use of 2D CNN only increased a less significant accuracy than 1D CNN. Evaluation of the waves shows that Beta and Gamma waves provided the best precision, 87-91%, and Theta waves gave 79-85% precision. Alpha wave degrades overall performance, which only has 56-61% precision, considering it is a mid-wave between Theta and Beta. It is necessary to choose the proper weight updating technique. Adaptive Moment (Adam) increased accuracy than AdaDelta, AdaGrad, and RMSprop.","PeriodicalId":339135,"journal":{"name":"2022 International Conference on Data Science and Its Applications (ICoDSA)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123951911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of them is Twitter, a service that allows users to send and read messages but is limited in character. Thus, tweets that are written are very short and do not always use the correct grammar and use many variations of words. Using word variations can increase the likelihood of vocabulary mismatches and make tweets difficult to understand. One solution to overcome this problem is to expand the features of the tweet. The feature expansion on Twitter is a semantic addition to the process of multiplying the original text to make it look like large text. In this study, Word2Vec will be used with the Gradient Boosted Decision Tree Method to classify it. The expected result of this research is to reduce words or sentences in the classification of Twitter topics which are evaluated using the accuracy value, F1-Measure. The highest accuracy value in the application of feature expansion using Word2Vec with the Gradient Boosted Decision Tree classification method is 85.44%.","PeriodicalId":339135,"journal":{"name":"2022 International Conference on Data Science and Its Applications (ICoDSA)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115804933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nutritional content of meat consists of fat, calories, trans fat, saturated fat, calcium, protein, vitamin D, vitamin B6, vitamin B12, and magnesium. Due to its good nutritional content, the demand for meat in Indonesia has increased. However, there are problems with meat health. Meat is prone to spoilage and is quickly contaminated with microbes. The microbial population can spoil or spoil the meat. Checking the feasibility of meat is usually done by looking at the texture of the meat traditionally. However, this method is less effective in assessing the feasibility of meat. Therefore, another method is used to determine the feasibility of meat, namely using the Electronic Nose (e-nose) with the Neural Network (NN) algorithm. Because by using an e-nose, that can find out the smell or smell of decent meat. They are applying the NN algorithm for classification to work in a structured manner on each component needed to determine meat quality. These results can help people to get the meat of good quality. The experiment was carried out using a dataset that had a total of 2220 data. The experimental results show that using the NN algorithm with the e-nose sensor gets an accuracy of 0.92.","PeriodicalId":339135,"journal":{"name":"2022 International Conference on Data Science and Its Applications (ICoDSA)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115247101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach is slow because computer networks produce massive amounts of data. Furthermore, new network intrusion variants continuously emerge. Retraining the model using these extensive and evolving data takes time and resources. This study proposes AB-HT: an ensemble incremental learning algorithm for IDSs. AB-HT utilizes incremental Adaptive Boosting (AdaBoost) and Hoeffding Tree algorithms. AB-HT model could detect new intrusions without retraining the model using old training data. Thus, it could reduce the computational resources needed to retrain the model while maintaining the model’s performance. We compared it to an AdaBoost-Decision Tree model, a batch learning model, to analyze the effectiveness of the incremental learning approach. Then we compared it to other incremental learning models, the Hoeffding Tree (HT) and Hoeffding Anytime Tree (HATT) models. The experimental results showed that the proposed incremental model had shorter training times than the AdaBoost-Decision Tree model in the long run. Also, on average, the AB-HT model has 18% higher F1-score values than the HT and HATT models. These advantages show that the AB-HT algorithm has promising potential to be used in the IDS field.","PeriodicalId":339135,"journal":{"name":"2022 International Conference on Data Science and Its Applications (ICoDSA)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129704541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meanwhile, when searching for videos on YouTube, the recommended videos are only videos found on YouTube, so the range of recommended videos is limited. To overcome this problem, we build a web-based video recommender system about diseases that is more organized with a wider range of videos taken from YouTube and Vimeo. In addition, the system not only recommends videos based on the searched keywords but also recommends videos based on videos that are liked by users. The YouTube and Vimeo APIs are used to retrieve videos about the disease being searched for. We use content-based filtering for the recommendation process. Keyword-based vector space does some tasks: 1) converts the title and description of a video into a vector space, 2) calculates the cross product of the term frequency, 3) determines the proximity of the title using cosine similarity. The test results show that the average performance is 92.67% according to the purpose of the recommendation system made, namely novelty and relevance.","PeriodicalId":339135,"journal":{"name":"2022 International Conference on Data Science and Its Applications (ICoDSA)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127943650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, in the aviation sector, flight traffic went down drastically with no certainty of being recovered. This calls for a methodology to predict the flight traffic to provide strategic planning on flight schedules operational, route structuring, and flight navigation service cost determination. However, current developments mainly focus on flight traffic forecasting based on historical data without considering external factors. In this study, we propose the Long Short-Term Memory (LSTM) technique to forecast flight traffic in Indonesia involving external variables such as macroeconomic variables and Google Trends. LSTM is proposed because of its flexibility to model non-linear time series data and has a good reputation for predictive accuracy. We first select a few among Google Trends and macroeconomic variables using nonlinearity analysis and cross-correlation function (CCF). We then employ the selected variables to forecast the flight traffic and compare it to the one using only historical flight traffic data. Our results concluded, based on the Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE), that the model involving google trend outperforms the other three models, i.e., the model with only historical data, the model with macroeconomics, and the model with both macroeconomic and Google Trends. It is because, in this digital era, Google Trends can reflect population psychology in an up-to-date manner.","PeriodicalId":339135,"journal":{"name":"2022 International Conference on Data Science and Its Applications (ICoDSA)","volume":"172 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120941306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
