huge_roc

Usage

huge_roc(path, theta, verbose=True, plot=False) -> HugeRocResult

Description

Native ROC computation across graph path estimates.

Key arguments

• path: sequence of adjacency matrices
• theta: ground-truth adjacency matrix containing at least one edge and one absent off-diagonal edge
• plot: if True, draw ROC curve via matplotlib helper

Returns

HugeRocResult with:

• f1: F1-score array
• tp: true-positive-rate array
• fp: false-positive-rate array
• auc: area under ROC curve

ROC/AUC is undefined for a one-class truth matrix, which is rejected with a clear error.
