Nomograms for Visualizing Linear Support Vector Machines

Support vector machines are often considered to be black box learning algorithms. We show that for linear kernels it is possible to open this box and visually depict the content of the SVM classifier in high-dimensional space in the interactive format of a nomogram. We provide a crosscalibration method for obtaining probabilistic predictions from any SVM classifier, which control for the genera...

The art of nomograms

Background To retrospectively analyse strategies for adjusting refractive surgery plans with reference to the preoperative manifest refraction. Methods We constructed seven nomograms based on the refractive outcomes (sphere, cylinder, axis [SCA]) of 150 consecutive eyes treated with laser in situ keratomileusis for myopic astigmatism. We limited the initial data to the SCA of the manifest ref...

Constructing Interactive Nomograms

Nomograms graphically encode mathematical relationships between multiple parameters. Historically, nomograms enjoyed wide use as analog computation devices, but understandably fell out of favor with the advent of more powerful calculators, computers, and related software. Yet, certain examples of nomograms encode complex relationships that are not easily visualized using more common forms such ...
