Towards Computationally Feasible Deep Active Learning

A repository to reproduce the experiments from the paper "Towards Computationally Feasible Deep Active Learning".

Installation

Install the library:

pip install -e .

Usage

The configs folder contains config files with general settings. The experiments folder contains config files with experimental design. To run an experiment with a chosen configuration, specify config file name in HYDRA_CONFIG_NAME variable and run train.sh script (see ./examples/al for details).

For example to launch PLASM on AG-News with ELECTRA as a successor model:

cd PATH_TO_THIS_REPO
HYDRA_CONFIG_PATH=../experiments/ag_news HYDRA_EXP_CONFIG_NAME=ag_plasm python active_learning/run_tasks_on_multiple_gpus.py

Config structure explanation

  • cuda_devices: list of CUDA devices to use: one experiment on one CUDA device. cuda_devices=[0,1] means using zero-th and first devices.
  • config_name: name of config from configs folder with general settings: dataset, experiment setting (e.g. LC/ASM/PLASM), model checkpoints, hyperparameters etc.
  • config_path: path to config with general settings.
  • command: .py file to run. For AL experiments, use run_active_learning.py.
  • args: arguments to modify from a general config in the current experiment. acquisition_model.name=xlnet-base-cased means that xlnet-base-cased will be used as an acquisition model.
  • seeds: random seeds to use. seeds=[4837, 23419] means that two separate experiments with the same settings (except for seed) will be run: one with seed == 4837, one with seed == 23419.

Output explanation

By default, the results will be present in the folder RUN_DIRECTORY/workdir_run_active_learning/DATE_OF_RUN/${TIME_OF_RUN}_${SEED}_${MODEL_CHECKPOINT}. For instance, when launching from the repository folder: al_nlp_feasible/workdir/run_active_learning/2022-06-11/15-59-31_23419_distilbert_base_uncased_bert_base_uncased.

  • When running a classic AL experiment (acquisition and successor models coincide, regardless of using UPS), the file with the model metrics is acquisition_metrics.json.
  • When running an acquisition-successor mismatch experiment, the file with the model metrics is successor_metrics.json.
  • When running a PLASM experiment, the file with the model metrics is target_tracin_quantile_-1.0_metrics.json (-1.0 stands for the filtering value, meaning adaptive filtering rate; when using a deterministic filtering rate (e.g. 0.1), the file will be named target_tracin_quantile_0.1_metrics.json). The file with the metrics of the model without filtering is target_metrics.json.

Datasets

The research has employed 2 NER datasets (CoNLL-2003, OntoNotes-2012) and 2 Text Classification (CLS) datasets (AG-News, IMDB). If one wants to launch an experiment on a custom dataset, they need to use one of the following ways to add it:

  1. Upload to Hugging Face datasets and set: config.data.path=datasets, config.data.dataset_name=DATASET_NAME, config.data.text_name=COLUMN_WITH_TEXT_OR_TOKENS_NAME, config.data.label_name=COLUMN_WITH_LABELS_OR_NER_TAGS_NAME
  2. Upload to data/DATASET_NAME folder, create train.csv / train.json file with the dataset, and set: config.data.path=PATH_TO_THIS_REPO/data, config.data.dataset_name=DATASET_NAME, config.data.text_name=COLUMN_WITH_TEXT_OR_TOKENS_NAME, config.data.label_name=COLUMN_WITH_LABELS_OR_NER_TAGS_NAME
  3. * Upload to data/DATASET_NAME train.txt, dev.txt, and test.txt files and set the arguments as in the previous point.
  4. ** Upload to data/DATASET_NAME with each folder for each class, where each file in the folder contains a text with the label of the folder. For details, please see the bbc_news dataset in ./data. The arguments must be set as in the previous two points.

* - only for NER datasets

** - only for CLS datasets

Models

The current version of the repository supports all models from HuggingFace Transformers, which can be used with AutoModelForSequenceClassification / AutoModelForTokenClassification classes (for CLS / NER). For CNN-based / BiLSTM-CRF models, please see the al_cls_cnn.yaml / al_ner_bilstm_crf.yaml configs from ./configs folder for details.
