One message on its way to the classifier.

Fields

label: Label

date: i64

account: String

place: Option<Place>

Your own mail: the copy learned from, and what decided its label.

evidence: Option<Evidence>

source: Option<usize>

Outside material: its source (an index into the training’s sources); none for your own mail.

ordinal: u64

Outside material: its rank in its source, as external::read_all reads it (detail).

unsettled: bool

Ham in an inbox, too young for its label to be settled (detail::unsettled).

known: bool

Its header features are known (your own mail); outside material’s are not: the centroid sets them to the mean, the classifier reads no word for them.

features: [f32; 35]

offset: u64

Where its words are in the tokenized corpus.

length: u64

words: u64
