Niels Klesper's Projects

deep_learning_challenge icon deep_learning_challenge

The purpose of the computer vision challenge was to develop a robust Convolutional Neural Network (CNN) capable of accurately classifying a patient's health statusโ€”distinguishing between a clean bill of health, bacterial pneumonia, viral pneumonia, or COVID-19.

machine_learning_challenge icon machine_learning_challenge

Our group project aimed to evaluate three predictive machine learning classification models to anticipate whether website visitors engage in transactions. This is done by analysing different attributes of website visitors including duration spent on different web pages, click rates, and bounce rates.

northwind_sales_dashboard icon northwind_sales_dashboard

The challenge aimed to design a comprehensive KPI dashboard catering to the needs of the management team. I initiated the process by processing the dataset using Excel. Afterwards, I drafted and implemented a MySQL database to support the dashboard infrastructure. The completion of the project resulted in the creation of a dynamic Tableau dashboard
