Biometrics Classification Using Audio Data and Machine Learning
Audio signal processing is an important aspect of the latest technological developments and has emerged as a leading element of research. It is gaining immense traction in the virtual assistant/BPO industry for designing Artificial Intelligence (AI) solutions. The paper focuses on the development of classification strategies based on the information pulled from voice data. The linear Support Vector Machine (SVM) and Random Forest (RF) classifiers render the best results for gender identification. The methodology that suited the requirements for age classification was Ridge Regression with costs, wherein the age groups were distributed among three classes. It was observed that the data imbalance fetched disappointing results, and it was concluded from the literature review that the Synthetic Minority Oversampling Technique (SMOTE) could potentially improve the output. Identity recognition involved open and closed classification, and the closed set delivered high returns. It was found that the size of the dataset was a limiting factor and stood in the way of securing higher accuracy. The findings also suggest that the models are trained more efficiently based on subject familiarization.
Internet of Things and Machine Learning for Weather Prediction
Weather predictions have conventionally been performed using complex models with satellite data and readings from weather stations. In recent times, modern technology has replaced these conventional techniques. However, obtaining accurate and precise weather predictions continues to remain extremely challenging. The paper proposes an architecture to enable weather forecasting using a combination of two modern technologies - Machine Learning (ML) and Internet of Things (IoT). By making use of the concept of crowd sensing and Collaborative Internet of Things (C-IoT), the paper proposes how a large amount of useful information can be collected and then processed using ML algorithms to arrive at meaningful results that aid in weather prediction. This can in turn help the IoT devices become more efficient in terms of energy consumption.
Weighing Prototype Simulation for Hogs with Web-Based Monitoring System Using Radio Frequency Identification
This study is about weighing the hogs in order to determine their growth and identifying them individually with Radio Frequency Identification (RFID) sensor. The system would read the data from the prototype simulation of the project and would be saved in the database. The data gathered in the database would be viewed on the website as graphical information of all the hogs and also their profile information would be viewed on the website. The study focuses on four aspects, namely, development of the prototype that can identify the weight of hogs using the RFID and capture the weight of the hogs using a weighing scale; development of the system that monitors the hog's weight and records it in the database automatically; providing graphical information of the hogs weight in the website; and capturing the effectiveness of the weighing prototype simulation for hogs with web-based monitoring system using RFID in terms of functionality, reliability, usefulness from the evaluators.
Predicting Students' Performance in a Nigerian Polytechnic Institution Using Data Mining Techniques of Neural Network, Support Vector Machine and K-Nearest Neighbor
The performance of students is an aspect of principal importance to educational institutions, as it determines the ranking and continuity of academic programs offered. The paper investigates the performance of students in a polytechnic institution, Department of Nigerian Education. Different factors that affect the performance of students were identified and classified. The factors considered include: National Diploma (ND) grade, time elapsed before admission for Higher National Diploma (HND), age, marital status, gender, region of origin and Polytechnic attended for ND. The seven factors were categorized and used to develop the models for the analysis. Three hundred and thirty-four (334) student records, after preprocessing, were reduced to 261 and used for the study. The data was collected directly from the examination and record office of the department and analyzed using the WEKA data mining tool to determine which classification algorithm model performs best on the dataset. Out of the three classification algorithms used, Support Vector Machine (SVM), outperformed both neural network and K-nearest neighbor classifiers with accuracy of 97.7%, precision of 97.8%, recall of 97.7% and f-measure of 97.7%. A comparative analysis of the three algorithms using accuracy, precision and recall and f-measure was done.
Radio Frequency Identification-Based Short Message Service Patient Alert Healthcare System
The present state of hospitals in Nigeria at large is worrisome. Normally, patients go to the hospital and fill out registration forms and face long queue before meeting a medical doctor for consultation. Patient registration system in most healthcare facilities is carried out using the traditional paper and pen which are kept in files assigned to patient's name. Also, the number of missed appointments in healthcare institutions in Nigeria causes more health challenges; hence the need for an Internet of Things (IoT)-based healthcare system to provide adequate and seamless care to patients. Therefore, the paper develops a prototype Radio Frequency Identification (RFID)-based Short Message Service (SMS) system for prompt medical response. The programming language used in creating the system was Python version 3.7.0 with SQLite as the database. An SMS alert system was integrated into the system to remind patients of their appointments with the doctors at the hospital within a specified time and day through the mobile phone numbers provided during registration. A delivery report is received by the system administrator and the message is delivered almost immediately to the patient's mobile phone number. The results of the prototype are demonstrated.
