Description

Machine learning (ML) is an evolving branch of computational algorithms that allows computers to learn from experience and historical datasets. It is one of the fast-growing research fields and has garnered much attention from academic and industrial researchers to discover the patterns and data representations from the raw data. It addresses manipulating, managing, mining, and understanding different data types to solve real-world challenges in different fields such as banking, transformation, and education. However, building a useful machine learning model is a challenging process that requires consideration of both time and performance.

Overall, machine learning’s main objective involves determining the best and most predictive model, which can be obtained by suitable feature engineering and hyper-parameters tuning. This is where the novel idea of automated machine learning (AutoML) emerged to automate the process of applying ML techniques and find optimal machine learning solutions and release the burden of huge development costs and manual processes. The challenges regarding ML models’ complicated and computationally expensive nature create significant opportunities for future research avenues on these steps, specifically on Hyper-Parameter Optimization (HPO) and Feature Selection Optimization (FSO) methods which are among the primary tasks in AutoML. The proposed approach will be implementing an automated system that addresses these issues and provides complete automatic steps to make well-performed time-efficient prediction models.
