Latu.ML.Feature.IDFModel (latu_ml v0.2.0)

Copy Markdown View Source

Attributes of a fitted IDFModel.

Every accessor here is one name on the server's allowlist for org.apache.spark.ml.feature.IDFModel — 3 of them — so tab completion is that allowlist. The server refuses anything else with CONNECT_ML.ATTRIBUTE_NOT_ALLOWED; these refuse a model of the wrong class before it gets that far, and name the module that would have taken it.

Allowed by the server but not here: toString is Identifiable's, and tells you less than the model's own uid. Latu.ML.attribute/2 and Latu.ML.attribute/3 will send any of these names; it is what comes back that has nowhere to go.

The allowlist is inherited rather than per class: this one is the union of org.apache.spark.ml.feature.IDFModel, org.apache.spark.ml.util.Identifiable.

Summary

Functions

The JVM class these accessors belong to.

Returns the document frequency.

Returns the IDF vector.

Returns number of documents evaluated to compute idf.

Functions

class()

@spec class() :: String.t()

The JVM class these accessors belong to.

doc_freq(holder)

@spec doc_freq(Latu.ML.Model.t()) :: {:ok, term()} | {:error, Latu.Error.t()}

Returns the document frequency.

An action: it reaches the server. A Vector or Matrix comes back as an Nx.Tensor, or a Latu.ML.SparseVector where densifying would be this package's decision rather than yours.

idf(holder)

@spec idf(Latu.ML.Model.t()) :: {:ok, term()} | {:error, Latu.Error.t()}

Returns the IDF vector.

An action: it reaches the server. A Vector or Matrix comes back as an Nx.Tensor, or a Latu.ML.SparseVector where densifying would be this package's decision rather than yours.

num_docs(holder)

@spec num_docs(Latu.ML.Model.t()) :: {:ok, term()} | {:error, Latu.Error.t()}

Returns number of documents evaluated to compute idf.

An action: it reaches the server. A Vector or Matrix comes back as an Nx.Tensor, or a Latu.ML.SparseVector where densifying would be this package's decision rather than yours.
