WTF1
WTF1 Click here to uncover the dirty truth about the F1 score Author Mickey Campbell Published July 2, 2025 Introduction For Sierra’s research on modeling fine-scale travel route selection in a wildland setting, we have been heavily focused on F1 score as the primary measure of model performance. F1 is widely regarded for its robustness as ...

NRD Height Range Analysis
NRD Height Range Analysis Introduction In the STRIDE manuscript, currently in review, that presents a new “universal” travel rate function trained and validated on three separate field experiments, we examined the aboveground height range within which lidar point normalized relative density (NRD) was most predictive of travel rates. We found t...
