Machine learning approaches for predicting student dropout

This study focuses on developing a machine learning model through the process of analyzing. comparing, and evaluating the performance of five models: AdaBoost, Decision Tree, RandomForest, ExtraTree, and BernoulliNB. All models are implemented using the "Predict Student Dropout Dataset." Based on the results obtained after processing the data, the study will conduct an analysis based on two main criteria: evaluation by average percentage, standard deviation, and final outcomes, as well as evaluation using a time-series model of age (Balanced Accuracy Progression).

Time series analysis and applications in data analysis, forecasting and prediction

Time series analysis is an essential field in data analysis, particularly within forecasting and prediction domains. Researching and building time series models play a crucial role in understanding and predicting the temporal dynamics of various phenomena. In mathematics, time series data is defined as data points indexed in chronological order and have a consistent time interval between consecutive observations.

Master's thesis of Business: Modelling dynamic financial linkages, spillover effects and volatility transmissions: empirical evidence from China and international financial markets

The rationale for this study is that the social enterprise sector provides an important locale in which to situate research that aims to identify the impact of ICTs on development. Recognising the complex dynamics and range of actors involved in this diverse and emerging area of development practice, this study chooses to focus on the social enterprise sector. It is specifically concerned with mapping the external influences, use and impact of ICT on social enterprises in Cambodia.

Doctoral thesis of Philosophy: The macroeconomic consequences of financialisation

Finance is considered as the lifeblood of the economy and it is integral to a country's economic growth and stability. However, this perception has been called into question, particularly following the global financial crisis, giving rise to new research questions. For example, does too much finance harm economic growth? And does the financial sector serve society's economic and social needs? This thesis aims to provide cross-sectional and time-series evidence on the macroeconomic consequences of financialisation in an international context.

Doctoral thesis of Philosophy: An economic analysis of the Australian Baby Bonus

The central objective of the thesis "An economic analysis of the Australian Baby Bonus" is to examine the nature of the fertility response of Australian families to the financial incentive of the Baby Bonus. The efficacy of the policy in determining a change in both fertility and the timing of births is assessed by exploring the time series properties of national and Victorian fertility measures, while controlling for other possible determinants of fertility choice.

Master’s thesis in international economics: The role of education in Chile’s economic growth

This thesis examines empirically whether there is a link between education and economic growth in Chile during the period 1973-2005. This is done through the adoption of time-series analysis and co-integration techniques. Based on economic theory and empirical findings, potential implications for Chilean educational policy are then discussed.

Báo cáo khoa học: Unravelling the functional interaction structure of a cellular network from temporal slope information of experimental data

Due to the unavoidable nonbiological variations accompanying many experiments, it is imperative to consider a way of unravelling the functional interaction structure of a cellular network (e.g. signalling cascades or gene networks) by using the qualitative information of time-series experimental data instead of computation through the measured absolute values.
