2024-02-01T23:32:30+00:00

Traffic classification refers to the processes used to categorize traffic based on features in the traffic and in accordance with specific classification objectives. In general, there are numerous forests, fields, and aims in the classification of internet traffic. Internet service providers must be aware of the types of traffic that are sent across their network Classifying Internet applications that are carried by computer networks is the specific goal, create a hybrid software classifier that can be applied to the classification of Internet traffic. Internet service providers (ISPs) attempt to boost bandwidth as a result of rising Internet traffic, but at the same time, more bandwidth is needed for Internet applications. Problems arise from the exponential growth of new internet applications using unregistered ports. The new programs may also contain a lot of viruses and dangerous code. In recent years, traffic classification has drawn more and more attention. With the help of direct and passive observation of the individual packets or stream of packets moving over the network, it seeks to provide the capability of automatically identifying the program that created a specific stream of packets. Data mining (DM) is a method for sifting through enormous databases in search of fresh, obscured, and practical information patterns. The knowledge discovery process includes the DM idea. This study employs a variety of techniques and functions as a hybrid classification. The foundation of many essential network monitoring and controlling jobs, such as billing, quality of service, security, and trend analyzers, is the classification of networks flows by their application type. Identification of Internet traffic is a crucial tool for network management. It enables operators to more accurately forecast upcoming traffic patterns and demand, and it enables security staff to spot unusual conduct.

Utilizing NLP Sentiment Analysis Approach to Categorize Amazon Reviews against an Extended Testing Set

2024-03-12T04:50:49+00:00

Sentiment analysis, also known as opinion mining, is a pivotal aspect of natural language processing (NLP). This method entails discerning the polarity of textual information and determining whether it conveys positive or negative sentiments. In one of the domains, e-commerce, sentiment analysis assumes paramount significance. It offers businesses a nuanced understanding of their brand and product sentiment as reflected in customer reviews, facilitating market comprehension and strategic decision-making. This study primarily focused on analyzing the Amazon food reviews dataset, augmenting the original dataset with newly generated data, and subsequently conducting data preprocessing tasks, encompassing text cleansing, removing stop words, lemmatization, and stemming. Subsequently, machine learning models were constructed, trained, and evaluated using NLP feature extraction techniques to address the sentiment analysis challenge and investigate the impact of increased data volume on model performance. Among the diverse methodologies employed for extracting features from textual data samples, this research integrated term frequency-inverse document frequency (TF-IDF), Word to Vector (W2V), and Bag of Words (BoW) techniques in the feature extraction phase. Furthermore, three distinct machine learning models, namely Logistic Regression, Decision Tree, and Random Forest, were designed, implemented, and assessed. The models' performance was scrutinized following hyperparameter optimization to determine the most effective approach. The outcomes revealed that the performance of the models was consistent, yielding accuracy rates ranging from 85% to 89% on the testing dataset. Nevertheless, the Logistic Regression model, employing BoW features, demonstrated superior performance compared to the other models. Following optimization of the logistic regression model, a remarkable accuracy of 89% was attained on the testing dataset by operating the BoW extracted features.

Wearable Sensors for Posture and Movement in Patient Handling: A Scoping Review

2024-02-02T13:27:20+00:00

Nurses experience work-related musculoskeletal disorders (WMSDs) such as lower back pain due to awkward postures or movements during patient handling. Monitoring and education for patient handling are necessary to prevent these WMSDs. Recently, measurement methods for patient handling using wearable sensors have been developed to implement these interventions at various sites. However, the status of these measurement methods has not been comprehensively summarized. The purpose of this study is to summarize the status of measurement methods for patient handling using wearable sensors. Peer-reviewed papers published between January 2013 and November 2023 that included measurements of patient handling using wearable sensors were selected from Google Scholar. Measured patient handlings, postures, and movements were summarized. The type, number, and placement of sensors were also investigated. Furthermore, the applied data processing techniques were also summarized. Inertial sensors and insole pressure sensors were applied for measurement methods. Current methods can measure trunk angle, arm movement, and foot placement during several motions such as patient transfer. In addition, load and correctness of patient handling motion are recognized by a wearable sensor-based system using machine learning techniques. These results indicate that current methods can provide effective kinematic values during patient handling to prevent WMSDs. On the other hand, there were also limitations due to number of sensors. Future studies should develop simpler measurement methods using fewer sensors.

Application of Text Summarization on Text-Based Generative Adversarial Networks

2023-12-30T00:44:39+00:00

In this project, we wish to convert long textual inputs into summarised text chunks and generate images describing the summarized text. This project aims to cultivate a model that can generate true-to-life images from summarized textual input using GAN. GANs aim to estimate and recreate the possible spread of real-world data samples and produce new pictures based on this distribution. This project offers an automated summarised text-to-image synthesis for creating images from written descriptions. The written descriptions serve as the GAN generator's conditional intake. The first step in this synthesis is the use of Natural Language Processing to bring out keywords for summarizing. BART transformers are employed. This is then fed to the GAN network consisting of a generator and discriminator. This project used a pre-trained DALL-E mini model as the GAN architecture.

Development of an Optimized Keyboard for the Tamazight Language: Integration of the Letter Frequency Model for Improved Ergonomics and Efficiency

2024-03-24T15:46:31+00:00

The need for an ergonomic keyboard layout to minimize strain on wrists and fingers during prolonged use has become increasingly important with the proliferation of digital devices. For languages without a standardized keyboard layout, such as Tamazight, makeshift solutions have been used, leading to discomfort and strain on the user's hands and wrists, occasionally resulting in conditions such as repetitive strain injury (RSI) and tendonitis in the wrists. This study presents a novel approach to developing an optimized keyboard layout for Tamazight that focuses on user comfort and minimizes strain on the wrists and fingers. A keyboard stress model was developed in which the keys are classified according to their degree of difficulty and stress, taking into account the position of the keys and the strength and length of the fingers. A textual analysis of novels and songs with over 17,000 words in Tamazight was conducted to determine for the first time the frequency-letter model for the Tamazight language, mainly Kabyle. The frequency of use of each letter was used to distribute them based on the estimated stress level for each finger on the keyboard. The resulting layout minimizes the need for frequent finger switching and includes all the necessary additional keys for Tamazight language use, which is a significant improvement and a major step forward for the standardization of the Tamazight keyboard. The finished layout was implemented with the Microsoft Keyboard Layout Creator (MSKLC).
