tech.ml.dataset.options — techascent/tech.ml.dataset 2.11

The etl pipeline and dataset operators are built to produce a metadata options map. Their API access to the options is centralized in this file.

column-label-map clj

(column-label-map options column-name)

dataset-label-map clj

(dataset-label-map options)

expand-column-names clj

(expand-column-names options colname-seq)

In the case of one-hot encoding, the column names may be expanded and the original column removed.

feature-column-names clj

(feature-column-names options)

feature-ecount clj

(feature-ecount options)

has-column-label-map? clj

(has-column-label-map? options column-name)

inference-target-label-inverse-map clj

(inference-target-label-inverse-map options)

Given options generated during ETL operations and annotated with :label-columns sequence container 1 label column, generate a reverse map that maps from a dataset value back to the label that generated that value.

(inference-target-label-map options)

label-column-names clj

(label-column-names options)

model-type-for-column clj

(model-type-for-column options column-name)

model-type-map clj

(model-type-map options & [colname-seq])

return a map of source label colname to model type.

num-classes clj

(num-classes options)

reduce-column-names clj

(reduce-column-names options colname-seq)

Inverse of expand column names. Reverse map from the one-hot encoded columns to the original source column.

set-dataset-label-map clj

(set-dataset-label-map options lmap)

set-feature-column-names clj
