}

The model learned from the oldest 80 %, whose numbers test gives, and how it was asked to learn (Options: the command line’s overrides too).

Fields

kind: String

Which model learned: “classifier” (fastText’s, the filter’s) or “centroid”.

word_ngrams: u32

The classifier’s word pairs (1: none) and learning rate.

lr: f64

dim: u32

vocabulary: u64

Words fastText kept.

bucket: u32

minn: u32

maxn: u32

epochs: u32

min_count: u32

Words seen fewer times were left out.

threads: u32

fastText’s threads.

costs: Vec<f64>

The SVM’s costs it chose from.

c: f64

The SVM’s cost chosen, and the validation AUC each cost had.

validation_auc: BTreeMap<String, f64>

ham_weight: f64

platt_a: f64

platt_b: f64

calibration_scores: u64

Scores the calibration was fitted on.

fold_error: f64

The largest difference between the table’s score and the model’s on the test messages.

table_bytes: u64

The size of the table written (the refit), or that would have been.

header_weights: BTreeMap<String, f64>

The classifier’s weight on each header feature, standardized (its pull for one deviation of the feature): what the header facts learned.
