To understand how hyperparameters (e.g., learning rate, batch size) and dataset characteristics (e.g., size, feature complexity) affect model performance (e.g., accuracy, overfitting), a correlation matrix analysis is the most effective method. This approach calculates correlation coefficients between all variables, revealing patterns and relationships-such as whether a higher learning rate correlates with increased overfitting or how dataset size impacts accuracy. NVIDIA's RAPIDS library, which accelerates data science workflows on GPUs, supports such analyses by enabling fast computation of correlation matrices on large datasets, making it practical for AI research.
PCA (Option B) reduces dimensionality but focuses on variance, not direct relationships, potentially obscuring specific correlations. Bar charts (Option C) are useful for comparing discrete values but lack the depth to show multivariate relationships. Pie charts (Option D) are unsuitable for trend analysis, as they only depict proportions. Correlation analysis aligns with NVIDIA's emphasis on data-driven insights in AI optimization workflows.
