Using deep learning neural networks to predict the knowledge economy index for developing and emerging economies

Abstract

Missing values and the inconsistency of the measures of the knowledge economy remain vexing problems that hamper policy-making and future research in developing and emerging economies. This paper contributes to the new and evolving literature that seeks to advance better understanding of the importance of the knowledge economy for policy and further research in developing and emerging economies. In this paper we use a supervised machine deep learning neural network (DLNN) approach to predict the knowledge economy index of 71 developing and emerging economies during the 1995-2017 period. Applied in combination with a data imputation procedure based on the K-closest neighbor algorithm, DLNN is capable of handling missing data problems better than alternative methods. A 10-fold validation of the DLNN yielded low quadratic and absolute error (0,382 +-0,065). The results are robust and efficient, and the model's predictive power is high. There is a difference in the predictive power when we disaggregate countries in all emerging economies versus emerging Central European countries. We explain this result and leave the rest to future endeavors. Overall, this research has filled in gaps due to missing data thereby allowing for effective policy strategies. At the aggregate level development agencies, including the World Bank that originated the KEI, would benefit from our approach until substitutes come along.

Let's Explore! The Factor, Reliability, and Validity Analyses of Readiness for a Knowledge-Based Economy Among Undergraduate Students

“…With knowledgebased economy readiness (KKE), undergraduate students are expected to reduce unemployment as they can create their jobs with the knowledge they possess. Also, by preparing for a K-economy, undergraduate students can improve the quality of their human resources (Andrés et al, 2021;Kurniati et al, 2021). In addition, readiness to face economic challenges indicates whether students are ready to face the economy when it comes to their economic knowledge.…”

Artificial neural network and decision tree-based modelling of non-prosperity of companies

“…The performance of the created models was then evaluated using several metrics in the evaluation phase of the CRISP-DM methodology. When applying some data mining approaches, the problem of overtraining may occur (Andrés et al, 2021;Borrellas & Unceta, 2021). To avoid this problem and create models with good generalizability, we used a combination of simple and five-fold cross-validation technique.…”

“…With several hidden layers present, DLNN can analyze the different nonlinear relationships present in the model [61,62], similar to the framework utilized in this study. Similarly, DLNN produces a higher accuracy rate due to the complex calculation present in the algorithm compared to other machine learning algorithms [70,71]. The datasets utilized came from all the responses made by the respondents.…”
