This is known as imbalanced data. When the machine learning models are trained using this imbalanced data, the models will be well trained for only 5-star rating reviews as it holds a bigger amount of product reviews compared to the other star ratings. In this case, even a bad review could make the models to interpret the review as a ...

This paper presents two open-source tools to increase precision and automate CFD simulations in OpenFOAM. The first is an adaptive mesh refinement method which uses custom field properties to refine both volume and surface cells. The second is a method to detect convergence and dynamically size the length of the averaging window to obtain reliable...
