Fig 3. Regression performance of single-model tools.

On 121 regression datasets, results are shown when executing three single-model tools, Weka, PyTorch, and MLpronto. (A) The box and whisker plot illustrates the performance of the tools as measured by R² score. The horizontal line (yellow) indicates the median R² score across the 121 regression datasets. The top and bottom of the box indicate the 25th percentile and the 75th percentile, respectively. The notches in a box represent the confidence interval around the median. The whiskers (red) extend from the box by 1.5 times the inter-quartile range. Outlier (flier) points are indicated as diamonds (gray). (B) The bar plot illustrates the mean runtime of training for each tool on the 121 regression datasets. Error bars (red) correspond to standard error.
