A novel ensemble approach for heterogeneous data with active learning

Abstract

At present, millions of internet users are contributing a huge amount of data. This data is extremely heterogeneous, and so, it is hard to analyze and derive information from this data that is considered an indispensable source for decision-makers. Due to this massive growth, the classification of data and analysis has become an important research subject. Extracting information from this data has become a necessity. As a result, it was necessary to process these enormous volumes of data to uncover hidden information and therefore improve data analysis and, in turn, classification accuracy. In this paper, firstly, we focus on developing an ensemble machine-learning model based on active learning which identifies the most effective feature extraction strategy for heterogeneous data analysis, and compare it with traditional machine-learning algorithms. Secondly, we evaluate the proposed model during the experiments; five heterogeneous datasets from various domains were used, such as a Health Care Reform dataset, Sander Frandsen dataset, Financial Phrase Bank dataset, SMS Spam Collection dataset, and Textbook sales dataset. According to the results, the novel approach for data analysis performed better than conventional methods. Finally, the study’s findings confirmed the validity of the suggested technique, meeting the study’s goal of using ensemble methods with active learning to raise the model’s overall accuracy for effectively classifying and analyzing heterogeneous data, reducing the time and money spent training the model, and delivering superior analysis performance as well as insights into other elements of extracting information from heterogeneous data.

The influence of firm-Generated video on user-Generated video: Evidence from China

“…The large amount of data collected can be analyzed using machine learning and other techniques to obtain hidden information. 92 The topics and comments of videos can also be analyzed for emotional polarity using sentiment analysis. 93 The information obtained can be used to build predictive models to analyze which videos better stimulate user-generated content.…”

A Machine Learning Approach to Forecast International Trade: The Case of Croatia

“…Additionally, the analysis could be extended by forecasting the horizon larger than one year; however, in that case, the precision of machine learning algorithms in predicting bilateral trade flows is expected to be lower. Another approach to which special attention should be paid is the ensemble approach, Salama et al (2022). The accuracy of machine learning algorithms and neural networks in predicting bilateral trade flows can be very beneficial for policymakers, researchers, and firms in making decisions related to international bilateral trade.…”

Dealing with missing values in proteomics data

“…Ensemble approaches are highly advanced, relying on a union of several independent paradigms to produce more accurate predictions compared to individual classifiers [40, 85]. An ensemble approach can be implemented with many weak learners and can accommodate large and heterogeneous data, making them highly suitable for supporting proteomic data analysis [86]. What makes ensemble methods so powerful, however, is that they can avoid overfitting and impute for MVs with a distribution that is closer to the true dataset [75].…”
