Active Learning for Text Classification in Python.

Installation | Quick Start | Contribution | Changelog | Docs

Small-Text provides state-of-the-art Active Learning for Text Classification. Several pre-implemented Query Strategies, Initialization Strategies, and Stopping Critera are provided, which can be easily mixed and matched to build active learning experiments or applications.

Features

• Provides unified interfaces for Active Learning so that you can easily mix and match query strategies with classifiers provided by sklearn, Pytorch, or transformers.
• Supports GPU-based Pytorch models and integrates transformers so that you can use state-of-the-art Text Classification models for Active Learning.
• GPU is supported but not required. In case of a CPU-only use case, a lightweight installation only requires a minimal set of dependencies.
• Multiple scientifically evaluated components are pre-implemented and ready to use (Query Strategies, Initialization Strategies, and Stopping Criteria).

What is Active Learning?

Active Learning allows you to efficiently label training data for supervised learning in a scenario where you have little to no labeled data.

News

Installation

Small-Text can be easily installed via pip (or conda):

pip install small-text

The command results in a slim installation with only the necessary dependencies. For a full installation via pip, you just need to include the transformers extra requirement:

pip install small-text[transformers]

For conda, which lacks the extra requirements feature, a full installation can be achieved as follows:

conda install -c conda-forge "torch>=1.6.0" "torchtext>=0.7.0" transformers small-text

The library requires Python 3.7 or newer. For using the GPU, CUDA 10.1 or newer is required. More information regarding the installation can be found in the documentation.

Quick Start

For a quick start, see the provided examples for binary classification, pytorch multi-class classification, and transformer-based multi-class classification, or check out the notebooks.
