FastTextes una biblioteca de Python desarrollada inicialmente por el laboratorio de investigación de IA de Facebook(FERIA)que proporciona una clasificación de texto eficiente y un aprendizaje de representación de Word. Ofrece un enfoque innovador para la representación de palabras, abordando algunas de las limitaciones de modelos anteriores como Word2Vec. Su capacidad para comprender vectores o elementos de subpalabras y manejar diversos desafíos lingüísticos lo convierte en una herramienta poderosa en el conjunto de herramientas de PLN. FastText se basa en distribuciones modernas de macOS y Linux. En este artículo, aprenderemos sobre el paquete de Python FastText y también sobre una versátil biblioteca de generación de PDF,IronPDF deIron Software.
Modelo de Representación de Palabras:
import fasttext
model = fasttext.train_unsupervised('data.txt', model='skipgram')
# data.txt is the training file
import fasttext
model = fasttext.train_unsupervised('data.txt', model='skipgram')
# data.txt is the training file
import fasttext model = fasttext.train_unsupervised( 'data.txt', model='skipgram')
#data.txt is the training file
print(model.words) # List of words in the dictionary
print(model['king']) # Vector for the word 'king'
print(model.words) # List of words in the dictionary
print(model['king']) # Vector for the word 'king'
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'print(model.words) # List @of words in the dictionary print(model['king']) # Vector for the word 'king'
model.save_model("model_filename.bin")
loaded_model = fasttext.load_model("model_filename.bin")
model.save_model("model_filename.bin")
loaded_model = fasttext.load_model("model_filename.bin")
'INSTANT VB TODO TASK: The following line uses invalid syntax:

El código demuestra cómo entrenar un modelo de clasificación de texto utilizando FastText:
import fasttext
# Training data file format: '__label__<label> <text>' with vocabulary words and out of vocabulary words
train_data = [
"__label__positive I love this!",
"__label__negative This movie is terrible.",
"__label__positive Great job!",
"__label__neutral The weather is okay."
]
# Write the training data to a text file with enriching word vectors
with open('train.txt', 'w', encoding='utf-8') as f:
for item in train_data:
f.write("%s\n" % item)
# Train a supervised model with training sentence file input
model = fasttext.train_supervised(input='train.txt', epoch=10, lr=1.0)
# Testing the model
texts = [
"I like it.",
"Not good.",
"Awesome!"
]
for text in texts:
print(f"Input text: '{text}'")
print("Predicted label:", model.predict(text))
print()
import fasttext
# Training data file format: '__label__<label> <text>' with vocabulary words and out of vocabulary words
train_data = [
"__label__positive I love this!",
"__label__negative This movie is terrible.",
"__label__positive Great job!",
"__label__neutral The weather is okay."
]
