Rare labels in categorical variables can cause significant issues in machine learning, such as overfitting. This article explains why rare labels can be problematic and provides examples on how to handle them.
Big data is revolutionizing climate science, enabling more accurate predictions and helping formulate effective mitigation strategies.
A study using GIS-based techniques for forest fire hotspot identification and analysis, validated with contributory factors like population density, precipitation, elevation, and vegetation cover.
Discover the reasons behind asymmetric confidence intervals in statistics and how they impact research interpretation.
Learn how to avoid false positives and false negatives in hypothesis testing by understanding Type I and Type II errors, their causes, and how to balance statistical power and sample size.
Polynomial regression is a popular extension of linear regression that models nonlinear relationships between the response and explanatory variables. However, despite its name, polynomial regression remains a form of linear regression, as the response variable is still a linear combination of the...
A deep dive into using Kernel Density Estimation (KDE) for identifying traffic accident hotspots and improving road safety, including practical applications and case studies from Japan.
Bayesian data science offers a powerful framework for incorporating prior knowledge into statistical analysis, improving predictions, and informing decisions in a probabilistic manner.
Julia Robinson was a trailblazing mathematician known for her work on decision problems and number theory. She played a crucial role in solving Hilbert’s Tenth Problem and became the first woman elected to the National Academy of Sciences.
PDEs offer a powerful framework for understanding complex systems in fields like physics, finance, and environmental science. Discover how data scientists can integrate PDEs with modern machine learning techniques to create robust predictive models.
