PredictorMLR3

<p>This task specializes Predictor for <code>mlr3</code> models.
The <code>model</code> is assumed to be a <code>LearnerRegr</code> or <code>LearnerClassif</code>.</p>
<p>It is recommended to use <code>makePredictor()</code> for construction of Predictor objects.</p>

Create local, regional, and global explanations for any machine learning model with forward marginal effects. You provide a model and data, and 'fmeffects' computes feature effects. The package is based on the theory in: C. A. Scholbeck, G. Casalicchio, C. Molnar, B. Bischl, and C. Heumann (2022) <doi:10.48550/arXiv.2201.08837>.
