In real-world applications, multi-view datasets often comprise diverse data sources or views, inevitably accompanied by noise. However, most existing graph-based multi-view clustering methods utilize fixed graph similarity matrices to handle noisy multi-view data, necessitating additional clustering steps for obtaining the final clustering. This paper proposes a Robust Joint Graph learning for Mul...Show More

In semiconductor manufacturing, the advancement of high-throughput sensors leads to the generation of high-dimensional and highly imbalanced data, presenting challenges like feature redundancy, increased computational costs, and bias in the classification models towards the majority class. These challenges complicate wafer defect classification, necessitating the integration of advanced feature se...Show More
In practical applications, the issue of data imbalance inevitably rises. In most studies, the predominant focus regarding long-tailed class imbalance pertains to a setting within a single domain in which the training and test samples are presumed to originate from the same feature space and possess identical data distributions. However, natural datasets can be derived from distinct domains in whic...Show More
Trainable parameters and hyperparameters are critical to the development of a deep learning model. However, the components have typically been studied individually, and most studies have found it difficult to investigate the effects of their combination on model performance. We are interested in examining the correlation between the number of trainable parameters in a deep learning model and its p...Show More
In vitro fertilization (IVF) involves collecting several mature egg samples fertilized with sperm in the IVF laboratory through a process of manual grading and selecting the healthiest blastocyst embryo through visual morphology assessment. Nevertheless, this manual process is highly subjective, prone to error and human bias, time-consuming, and can result in multiple pregnancies. Since the gradin...Show More
In-Vitro fertilization (IVF) is the most successful form of assisted reproductive technology and one of the most used fertility treatments. According to a prior study, the day 3 embryo development stage is a crucial transitional time that significantly impacts the pregnancy and implantation rates of day 5 transfers. Most embryologists currently analyze the morphological characteristics of day 3 em...Show More
Recently, accurate predicting outpatient visits is crucial in healthcare for optimizing service delivery and resource allocation. Time series models, particularly Deep Learning (DL) methods, have gained popularity in predicting demand and can potentially be used to predict demand for medical services, including outpatient hospital visits. This study aims to assess the potential of Bidirectional Lo...Show More
Multiple perspectives can be used to explore rich and complex datasets that are widely used in many applications. However, in real-world applications, the multi-view data are often noisy because of various environmental factors. The key challenge of graph-based multi-view clustering is obtaining a consistent clustering structure. Most graph-based methods learn independently in one view how similar...Show More
This study optimized the latest YOLOv5 framework, including its subset models, with training on different datasets that differed in image contrast and cloudiness to assess model performances based on quantitative metrics and image processing speed. The hyperparameter in the feature-extraction phase was configured based on the learning rate and momentum and further improved based on the adaptive mo...Show More
With the increasing pressure from the market and the surge of “Industry 4.0,” staying competitive and relevant is becoming more and more difficult. The assembly line, which represents a long-term investment of the manufacturing industry, needs to be efficiently utilized. While assembly line balancing (ALB) problem had been studied for decades, oversights on the bottleneck resources could significa...Show More
Credit card fraud is a serious and growing problem. It is becoming more challenging with an issues of highly imbalanced class. In the field of data mining, prediction or typically known as data classification problem involved detecting events. Uncommon events are hard to identify on account of their inconsistency and casualness, however, misclassifying rare events can result in heavy costs. Thus, ...Show More
The advent of industrial 4.0 ushered a new era in the manufacturing industry where merely optimizing the available resources is not enough to fulfill the need of the growing market. Various approaches have addressed the assembly line balancing (ALB) problem for decades. Although solving the ALB problem is crucial, a bottleneck may still occur over the next operation stages. As such, two research d...Show More
Feature selection (FS) aims to select the subsets of the most informative features by ignoring the redundant ones and consequently, improving the classification performance. Hence, consider as a two objective optimisation problem. Moreover, most of the existing work treats FS as single-objective by combining the two aims into a single fitness function. As such, there is a trade-off between the num...Show More
Feature selection aims to confiscate inappropriate features and yet improve classification performance. These aims are conflicting with one another, and a choice must be made in the presence of the trade-off between them. Numerous researches deal with feature selection problem but, they are mostly single-objective based. Nowadays, multi-objective optimisation approaches are becoming the most suita...Show More
Usually, data sets used in computer network research are not widely shared because of the risk of security breach.

Furthermore, it helps researchers to understand the real nature of huge workload in cloud data centres. This paper aims to collect and summarize the characteri...Show More
In an educational institution, various students criteria contributed to the main reason the student is nominated as a model student. This includes cumulative grade point average (CGPA) of academic courses taken, co-curriculum involvement, soft skills, hard work, leadership, attitude, time management, attendance, attire, and technical skill in order to make the selection decision. The distinctive s...Show More
Emergency often create panic and stress in crowd. The human emotional transition between normal to panic state is due to extreme event which is beyond control. In the past, crowd behavior models for emergency evacuation being studied are aircraft emergency evacuation, emotional ant based, behavior based real time evacuation and many more which is related to the behavior and life like. They are dif...Show More
In the event of natural disasters, catastrophes or war, efficient tools are needed to produce evacuation plans to evacuate the crowd safely. Disaster is an unplanned situation that can happen anywhere and anytime. The worst case is when disasters happen on large gatherings which can increase risk of death during egress evacuation. When an emergency arises, crowds will evacuate to the nearest exit ...Show More
The occurrence of emergency events tends to spark a very chaotic reaction, inducing a large surge of demand (number of evacuees) which exceeds the available resources (pathway/network). Planning a suitable evacuation route and identifying the shortest evacuation route before the occurrence of extreme events are crucial for an effective evacuation process. Although evacuation plans can be orchestra...Show More
In general, people like to cook but they have no idea on what to cook and how to cook. Furthermore, they also wish to know certain recipes that suit to their preference.
