An Investigation of Translation of Text Language to Sign Language Using Machine Learning (Published)

Among the fastest-growing areas of study today is the translation of sign language, which is the most natural form of communication for those with hearing loss. Deaf individuals may be able to communicate with hearing people directly, without an intermediary, with the use of a hand gesture recognition device. The method was developed to facilitate the automatic translation of American Sign Language into text and sound. The suggested system uses a large data collection to interpret individual words and phrases in traditional American Sign Language, alleviating any fears that the user may have about using a virtual camera. Deaf and mute persons must rely on Sign Language as their only method of communication. However, a large portion of the general public is illiterate in sign language. Therefore, those who sign have a more difficult time communicating with those who don’t without the help of an interpreter. The proposed technique employs data collected by Fifth Dimension Technologies (5DT) gloves to try to interpret hand movements as spoken language. The data has been classified into text words using a variety of machine learning techniques, including neural networks, decision tree classifiers, and k-nearest neighbors.

External vs. Internal: An Essay on Machine Learning Agents for Autonomous Database Management Systems (Published)

There are many possible ways to configure database management systems (DBMSs) have challenging to manage and set.The problem increased in large-scale deployments with thousands or millions of individual DBMS  that each have their setting requirements. Recent research has explored using machine learning-based (ML) agents to overcome this problem’s automated tuning of DBMSs. These agents extract performance metrics and behavioral information from the DBMS and then train models with this data to select tuning actions that they predict will have the most benefit. This paper discusses two engineering approaches for integrating ML agents in a DBMS. The first is to build an external tuning controller that treats the DBMS as a black box. The second is to incorporate the ML agents natively in the DBMS’s architecture.

A model for Real Estate Price Prediction using Multi-Level Stacking Ensemble Technique (Published)

Recent research and economic publications have shown the impact of real estate investment on the over economy of Nigeria. It is therefore crucial to employ machine learning technique to predict the price for real estate properties. Real estate price analysis and prediction will assist in establishment of real estate policies and can also be used to aid real estate property stakeholders to come up with informative decisions without bias or prejudice. Thus, it is imperative to develop a model to improve the accuracy of real estate price prediction. The goal of this research is to develop a model using a multi-level stacking ensemble technique to predict price of real estate property. The dataset utilized for the study was collected from transactions done by real estate firms in Port Harcourt and it consist of a total of 1053 rows with twelve features. The base model used includes Random Forest(RF), Extreme Gradient Boosting Algorithm(XGBoost), Light Gradient Boosting Machine(LightGBM), Decision Tree regression and ElasticNet Regression. Various combinations of the base models were stacked using StackingCVRegressor. The final model was developed by combining the best performing stacked models and evaluated using R-Square, Mean Absolute Error(MAE), Root Mean Square Error(RMSE), Mean Square Error(MSE) and Training time. The proposed model outperformed the various individual base model with R-square of 0.985203, MSE of 0.013438, RMSE of 0.115923, MAE of 0.063411 and training time of 0.599398. The result show that multi-level stacking significant improve the accuracy of a model. Again, it was observed stacking improve the performance accuracy of a model at the cost of computational time. Stacking by using blending function for the proposed model significantly reduced the computational time for training the model to 0.599398 second when compared to using StackingCVRegressor with training time of 107.054931 seconds. Therefore, multi-level stacking ensemble technique can be employed to improve the predictive accuracy of a prediction model. Future work can be done by increasing the dataset and also increasing the number of features.

The Importance of Machine Learning Techniques in Malware Detection: A Survey (Published)

In the current age, keeping pace with the evolution of malware is becoming immensely challenging each day. In order to keep up with the unconventional trend in the development of malware, it is imperative to develop intelligent malware detection methods that accurately identify malicious files from real world data samples. The sheer complexity and volume of malware attacks on a day-to-day basis has given rise to the need of utilising machine learning techniques for dynamic analysis of files and data. In this paper, types of malware are described to understand the scope of the problem and the traditional techniques that are used for malware detection. Dynamic and behaviour-based detection methods coupled with machine learning techniques are considered to be at the core of future research and progress. Unfortunately, there are still a plethora of problems and challenges to overcome like polymorphic malware, black-box models of machine learning algorithms, reverse engineering, theoretical and practical research gaps that limit our progress and success. It is crucial to find solutions as malware experts are also exploring and exploiting the concepts of machine learning for advanced malware development and better elusive techniques. Additionally, it is required to bridge the gap between malware and machine learning experts. Their combined expertise can secure better results. In conclusion, future research direction in the field of malware detection is presented.

Analysis and forecasting the outbreak of Covid-19 in Ethiopia using machine learning (Published)

Coronavirus outbreaks affect human beings as a whole and can be a cause of serious illness and death. Machine learning (ML) models are the most significant function in disease prediction, such as the Covid-19 pandemic, in high-performance forecasting and used to help decision-makers understand future situations. ML algorithms have been used for a long time in many application areas that include recognition and prioritization for certain treatments. Too many ML furcating models are used to deal with problems. In this study, predict a pandemic outbreak using the ML forecasting models. The models are designed to predict Covid-19, depending on the number of confirmed cases, recovered cases and death cases, based on the available dataset. Support Vector Machine (SVM) and Polynomial Regression (PR) models were used for this study to predict Covid-19 ‘s aggressive risk. All three cases, such as confirmed, recovered and death, models predict death in Ethiopia over the next 30 days. The experimental result showed that SVM is doing better than PR to predict the Covid-19 pandemic. According to this report, the pandemic in Ethiopia increased by half between the mid of July 2020. Then Ethiopia will face a number of hospital shortages, and quarantine place.
