In the published paper, Tables 1 and 2 were advertently switched. The corrected tables are provided herein. Additionally, the following changes should be made to the text to reflect the correct table callouts:
| popsize | maxgen | |||
|---|---|---|---|---|
| 0.9 | 2.5 | 0.5 | 10 | 100 |
Note: popsize = size of population; and maxgen = maximum number of generations.
| Hyperparameter | Description | Determination method |
|---|---|---|
| ntree | Number of decision trees | PSO |
| mtry | Maximum number of features at nodes | PSO |
| min_sample_split | Minimum number of samples for splitting nodes | 2 |
| min_sample_leaf | Minimum number of samples at leaf nodes | 5 |
| max_depth | Maximum depth of a tree | Automatic |
On page 04022021-4, “The hyperparameters of RF are summarized in Table 2 (Probst et al. 2019).”
On Page 04022021-6, “Table 3 summarizes the number of each type of grain on the studied slice image, as well as the results generated by the RF-based model and watershed algorithm.”
The authors regret the errors.
To preserve the published version of record, these details have been corrected only in this erratum.
