    Full text link
    The comparative study is performed on improved Novel Enhanced Gradient Boosting Algorithm (NEGB) and KNearest Neighbors (KNN) Algorithm, which determines the patient’s duration of staying in hospitals. The Novel Enhanced Gradient Boosting by taking the highest priority of maximized gain is proposed. The proposed algorithm implements Novel Enhanced Gradient Boosting framework with maximized gain probability. The Novel Enhanced Gradient Boosting algorithm and K-Nearest Neighbors Algorithm used in this research article. The concrete evidence for the performance evaluation, the sample size prejudge mental tools were used under the conditions of gpower 0.8, alpha 0.05 and confidence interval 95% during the estimation. The NEGB has a better accuracy rate (89.90%) compared to KNN has the accuracy rate (74.25%). The significance of 0.241 (p>0.05) value implies that experiment driven in this research was insignificant. The NEGB Algorithm is good in recalculating the stay duration of patients and also improves accuracy more than the K-Nearest Neighbors algorithm

    No full text
    The most common network attacks are Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks which causes packet loss by delaying the exchange of information, thereby altering the data packets sent through networks which affect the integrity and reliability of the data. Over time, various machine learning models have been identified and presented by researchers to predict and prevent DoS and DDoS attacks. Many researchers have proposed and used different machine learning techniques to predict DoS and DDoS attacks, however, there is still a need for improvement in the accuracy of prediction and more evaluation of these algorithms and a need for more algorithms to be explored. Hence, this paper improves on existing works by re-evaluating and comparing the accuracy between Decision Tree and Random Forest Algorithms in predicting DDoS attacks. The results of the paper show that Random Forest (RF) Regression model is the best-fit model for the cleaned DDoS SDN dataset used because it is more accurate as it has a lesser mean squared error of 0.21091041940417007 for the test data compared to the mean squared error value of Decision Tree Regression (DTR) Model. Hence, the paper concludes that the RF model is the best-fit model to be used in predicting DDoS attacks. However, the paper proposes that more machine learning algorithms should be explored, implemented, and re-evaluated in detecting DDoS attacks

    Technological innovation for digital supply chains within small and medium size manufacturing enterprises

    Full text link
    The rapidly growing world of digitalisation opens the doorway for the new era of automation that plays a crucial role within the industry. Furthermore, technological innovations that are emerging every day are disrupting traditional business processes especially within small and medium size manufacturing enterprises (SMEs). The current industrial revolution pioneer for profit maximisation with cost reduction shows a significant refinement in improving sustainability that drives forward digitalisation. Evidence shows that industries have identified digitalisation as a priority in the upcoming years as the global supply chain is equipping itself with the digital world in the current industrial revolution. Economic growth is dependent on SMEs around the world where small and medium size Manufacturing Enterprises (SMMEs) play a vital role in the current competitive world while they are not able to manage their supply chains effectively and efficiently due to a lack of optimisation of digitalisation. They identify that technological innovation is evident for transforming themselves with digital supply chain, while global market leading organisations are positioning themselves with the world of digitalisation to their end consumers in their supply chain utilising technological innovation virtually driving towards a new era of a digital ecosystem. This research aims to investigate the impact of technological innovation to foster and promote digital supply chain within SMMEs. Due to the exploratory nature, this study adopted a case study approach where the data is collected using a semi-structured interview across 4 cases from three various countries. The findings indicate a lack of framework for the digitalisation of supply chains within SMMEs, in addition to a lack of technological innovation and financial constraints that served as limiting factors for digitalisation of supply chain within organisations. Further, a framework has been developed consisting of five elements that have been identified from empirical data as being critical for Digital Supply Chain (DSC) transformation. The theoretical contributions of this research are the identification of problems faced, limitations of technological innovation, and an improved understanding of how digital supply chain transformation can be initiated and achieved in the context of SMMEs. The practical contribution of this study is imbedded in the developed framework in the form of recommended strategies for SMMEs for digitalisation of supply chain

    No full text
    This study conducted an exploratory analysis of bicycle crash data from Great Britain with the aim of identifying the key variables that influence the classification of such incidents. It also analysed data on a range of factors that may contribute to bicycle crashes, including the age of the cyclist, lighting conditions, weather conditions, road types, road conditions, and speed limits. Results indicated that these variables are among the most significant predictors of bicycle crashes, with road conditions, time of day, and lighting conditions being particularly vital factors. In addition, the study sought to compare the efficacy of different machine learning and deep learning models in predicting the severity of such incidents. Results indicated that these models demonstrated poor performance in predicting the severity of bicycle crashes. As a result, a hybrid model that combines the K-Nearest Neighbor and eXtreme Gradient Boosting algorithms was developed to improve accuracy. The hybrid model outperformed all other models, achieving an accuracy rate of 83.56%. The study, additionally, has put forward several recommendations, including the mandatory use of reflective clothing and the installation of Intelligent Transportation Systems (ITS) to enhance the safety of cyclists

    Peter Bullimore: A living tribute

    Full text link
    The aim of this paper is to provide a living tribute of the mental health activist and international trainer Peter Bullimore. Peter provided a list of people who he wanted to provide tributes. Jerome approached all these people. All agreed. Several people from around the world attest to the influence that Peter's teaching and personality has had on their clinical practice and on their lives. The disappearance of Open Mind has left a shortage of journals which welcome the user perspective. Mental Health and Social Inclusion has always championed the voice of people with lived experience. These are selected tributes to one man’s work in the field of mental health. These accounts provide insights into the work of a remarkable individual. Students of the mental health professions are mainly exposed to work produced by their peers. The history of mental health is filled with the stories of professionals, not the people who have used services. Historically accounts of psychiatry are written by mental health professionals. Service user or lived experience accounts are often written from the perspective of the person’s story of illness and recovery. There are comparatively few which celebrate the additional achievements of specific individuals with lived experience

    Enhanced preprocessing approach using ensemble machine learning algorithms for detecting liver disease

    Full text link
    There has been a sharp increase in liver disease globally, and many people are dying without even knowing that they have it. As a result of its limited symptoms, it is extremely difficult to detect liver disease until the very last stage. In the event of early detection, patients can begin treatment earlier, thereby saving their lives. It has become increasingly popular to use ensemble learning algorithms since they perform better than traditional machine learning algorithms. In this context, this paper proposes a novel architecture based on ensemble learning and enhanced preprocessing to predict liver disease using the Indian Liver Patient Dataset (ILPD). Six ensemble learning algorithms are applied to the ILPD, and their results are compared to those obtained with existing studies. The proposed model uses several data preprocessing methods, such as data balancing, feature scaling, and feature selection, to improve the accuracy with appropriate imputations. Multivariate imputation is applied to fill in missing values. On skewed columns, log1p transformation was applied, along with standardization, min–max scaling, maximum absolute scaling, and robust scaling techniques. The selection of features is carried out based on several methods including univariate selection, feature importance, and correlation matrix. These enhanced preprocessed data are trained on Gradient boosting, XGBoost, Bagging, Random Forest, Extra Tree, and Stacking ensemble learning algorithms. The results of the six models were compared with each other, as well as with the models used in other research works. The proposed model using extra tree classifier and random forest, outperformed the other methods with the highest testing accuracy of 91.82% and 86.06%, respectively, portraying our method as a real-world solution for detecting liver disease

    No full text
    Water is life, human and all activities of living things needs water for its survival. There are growing concerns about the quality of water available for human consumption and other daily human activities. The pollution of water are traceable to economic activities, industrialization, urbanization, agricultural activities and other human activities. These activities also affect human life and water quality. This concern has necessitated the studies on prediction of water quality and an efficient water monitoring system. The most common method of ensuring good quality of water is by testing them in the laboratory, this current method wastes time, not economical, wastes human power. Many studies on the use of Artificial neural network and machine learning models to predict the quality of water has been on the increase, this study creates an Artificial neural network and random forest regression machine learning model using parameters such as ph., Hardness, Conductivity, Solids, Conductivity, Turbidity, Portability and does a comparative analysis of the best fit model and it was determined that the random forest model had the best fit model with a lower mean squared error of 2.325103283606211 when compared to the Artificial neural network with a mean squared error of 3.3122911 by determining the model with the least mean squared error. This study postulates that random forest method is the best fit model for prediction of water quality when compared to the Artificial neural network

    Flame Retardancy Index ( FRI ) for Polymer Materials Ranking

    Full text link
    In 2019, we introduced Flame Retardancy Index (FRI) as a universal dimensionless index for the classification of flame-retardant polymer materials (Polymers, 2019, 11(3), 407). FRI simply takes the peak of Heat Release Rate (pHRR), Total Heat Release (THR), and Time-To-Ignition (ti) from cone calorimetry data and quantifies the flame retardancy performance of polymer composites with respect to the blank polymer (the reference sample) on a logarithmic scale, as of Poor (FRI ˂ 100), Good (100 ≤ FRI ˂ 101), or Excellent (FRI ≥ 101). Although initially applied to categorize thermoplastic composites, the versatility of FRI was later verified upon analyzing several sets of data collected from investigations/reports on thermoset composites. Over four years from the time FRI was introduced, we have adequate proof of FRI reliability for polymer materials ranking in terms of flame retardancy performance. Since the mission of FRI was to roughly classify flame-retardant polymer materials, its simplicity of usage and fast performance quantification were highly valued. Herein, we answered the question “does inclusion of additional cone calorimetry parameters, e.g., the time to pHRR (tp), affect the predictability of FRI?”. In this regard, we defined new variants to evaluate classification capability and variation interval of FRI. We also defined the Flammability Index (FI) based on Pyrolysis Combustion Flow Calorimetry (PCFC) data to invite specialists for analysis of the relationship between the FRI and FI, which may deepen our understanding of the flame retardancy mechanisms of the condensed and gas phases
