text-classification-baseline 0.1.0

TF-IDF + LogReg baseline for text classification

Text Classification Baseline

Pipeline for building text classification TF-IDF + LogReg baselines using sklearn.

Usage

Instead of writing custom code for specific text classification task, you just need:

1. install pipeline:

pip install text-classification-baseline

2. run pipeline:

   • either in terminal:

   text-clf --config config.yaml
   

   • or in python:

   import text_clf
   
   text_clf.train(path_to_config="config.yaml")
   

No data preparation is needed, only a csv file with two raw columns (with arbitrary names):

• text
• target

NOTE: the target can be presented in any format, including text - not necessarily integers from 0 to n_classes-1.

Config

The user interface consists of only one file config.yaml.

Change config.yaml to create the desired configuration and train text classification model.

Default config.yaml:

seed: 42
verbose: true
path_to_save_folder: models

# data
data:
  train_data_path: data/train.csv
  valid_data_path: data/valid.csv
  sep: ','
  text_column: text
  target_column: target_name_short

# tf-idf
tf-idf:
  lowercase: true
  ngram_range: (1, 1)
  max_df: 1.0
  min_df: 0.0

# logreg
logreg:
  penalty: l2
  C: 1.0
  class_weight: balanced
  solver: saga
  multi_class: auto
  n_jobs: -1

Output

After training the model, the pipeline will return the following files:

• model.joblib - sklearn pipeline with TF-IDF and LogReg steps
• target_names.json - mapping from encoded target labels from 0 to n_classes-1 to it names
• config.yaml - config that was used to train the model
• logging.txt - logging file

Requirements

Python >= 3.7
