Quick Start

To train a binary classifier from text files:

from deeplotx.util import get_files, read_file
from deeplotx import TextBinaryClassifierTrainer, LongTextEncoder

long_text_encoder = LongTextEncoder(
  max_length=2048,
  chunk_size=512,
  overlapping=128
)

trainer = TextBinaryClassifierTrainer(
  long_text_encoder=long_text_encoder,
  batch_size=4,
  train_ratio=0.9
)

pos_data_path = './data/pos'
neg_data_path = './data/neg'
pos_data = [read_file(x) for x in get_files(pos_data_path)]
neg_data = [read_file(x) for x in get_files(neg_data_path)]
model = trainer.train(pos_data, neg_data, num_epochs=20, learning_rate=2e-5, train_loss_threshold=1)
model.save()

model = model.load()
model.predict(long_text_encoder.encode('这是一个测试文本.').squeeze())
