mccf1: R package for the MCC-F1 curve

Many fields use the receiver operating characteristic (ROC) curve and the precision-recall (PR) curve as standard evaluations of binary classification methods. Analysis of ROC and PR, however, often gives misleading and inflated performance evaluations, especially with an imbalanced ground truth. In our preprint, "The MCC-F1 curve: a performance evaluation technique for binary classification", we propose the MCC-F1 curve to address these drawbacks. The MCC-F1 curve combines two informative single-threshold metrics, Matthews correlation coefficient (MCC) and the F1 score. The MCC-F1 curve more clearly differentiates good and bad classifiers, even with imbalanced ground truths. We also introduce the MCC-F1 metric, which provides a single value that integrates many aspects of classifier performance across the whole range of classification thresholds. This project is an R package that plots MCC-F1 curves and calculates related metrics.

Qal'bu Maryam Women's Mosque

As a pro bono project, I worked on the PR for a new, radically inclusive, women-led mosque in Berkeley, California. It's only the second women's-led mosque in the US and the first that allows genders to pray together. The dedication ceremony and prayer service was held April 14, 2017, and got a lot of press, including TV reports and other coverage. [more inside]
