predict.Rcpp_fastrtext: Get predictions (for supervised model)

In fastrtext: 'fastText' Wrapper for Text Classification and Word Representation

Description

Apply the trained model to new sentences. Average word embeddings and search most similar label vector.

Usage

## S3 method for class 'Rcpp_fastrtext'
predict(object, sentences, k = 1,
  simplify = FALSE, unlock_empty_predictions = FALSE, threshold = 0,
  ...)

Arguments

object	trained fastText model
sentences	character containing the sentences
k	will return the k most probable labels (default = 1)
simplify	when TRUE and k = 1, function return a (flat) numeric instead of a list
unlock_empty_predictions	logical to avoid crash when some predictions are not provided for some sentences because all their words have not been seen during training. This parameter should only be set to TRUE to debug.
threshold	used to limit number of words used. (optional; 0.0 by default)
...	not used

Value

list containing for each sentence the probability to be associated with k labels.

Examples

library(fastrtext)
data("test_sentences")
model_test_path <- system.file("extdata", "model_classification_test.bin", package = "fastrtext")
model <- load_model(model_test_path)
sentence <- test_sentences[1, "text"]
print(predict(model, sentence))
