CLARIN Embeddings

State-of-the-art Text Representations for Natural Language Processing tasks, an initial version of library focus on the Polish Language

This library was used during the development of the LEPISZCZE benchmark (NeurIPS 2022).

Installation

pip install clarinpl-embeddings

Example

Text-classification with polemo2 dataset and transformer-based embeddings

from embeddings.pipeline.lightning_classification import LightningClassificationPipeline

pipeline = LightningClassificationPipeline(
    dataset_name_or_path="clarin-pl/polemo2-official",
    embedding_name_or_path="allegro/herbert-base-cased",
    input_column_name="text",
    target_column_name="target",
    output_path="."
)

print(pipeline.run())

⚠️ As for now, default pipeline model hyperparameters may provide poor results. It will be subject to change in further releases. We encourage users to use Optimized Pipelines to select appropriate hyperparameters.

Conventions

We use many of the HuggingFace concepts such as models (https://huggingface.co/models) or datasets (https://huggingface.co/datasets) to make our library as easy to use as it is possible. We want to enable users to create, customise, test, and execute NLP / NLU / SLU tasks in the fastest possible manner. Moreover, we present easy to use static embeddings, that were trained by CLARIN-PL.

Pipelines

We share predefined pipelines for common NLP tasks with corresponding scripts. For Transformer based pipelines we utilize PyTorch Lighting ⚡ trainers with Transformers AutoModels . For static embedding based pipelines we use Flair library under the hood.

Transformer embedding based pipelines (e.g. Bert, RoBERTA, Herbert):

Task	Class	Script
Text classification	LightningClassificationPipeline	evaluate_lightning_document_classification.py
Sequence labelling	LightningSequenceLabelingPipeline	evaluate_lightning_sequence_labeling.py

Run classification task

The example with non-default arguments

python evaluate_lightning_document_classification.py \
    --embedding-name-or-path allegro/herbert-base-cased \
    --dataset-name clarin-pl/polemo2-official \
    --input-columns-name text \
    --target-column-name target

Run sequence labeling task

The example with default language model and dataset.

^{*only pair classification task is supported for now}

Passing task model and task training parameters to predefined flair pipelines

Model and training parameters can be controlled via task_model_kwargs and task_train_kwargs parameters that can be populated using the advanced config. Tutorial on how to use configs can be found in /tutorials directory of the repository. Two types of config are defined in our library: BasicConfig and AdvancedConfig. In summary, the BasicConfig takes arguments and automatically assign them into proper keyword group, while the AdvancedConfig takes as the input keyword groups that should be already correctly mapped.

The list of available config can be found below:

Lightning:

LightningBasicConfig
LightningAdvancedConfig

Example with `polemo2` dataset

Lightning pipeline

from embeddings.config.lightning_config import LightningBasicConfig
from embeddings.pipeline.lightning_classification import LightningClassificationPipeline

config = LightningBasicConfig(
    learning_rate=0.01, max_epochs=1, max_seq_length=128, finetune_last_n_layers=0,
    accelerator="cpu"
)

pipeline = LightningClassificationPipeline(
    embedding_name_or_path="allegro/herbert-base-cased",
    dataset_name_or_path="clarin-pl/polemo2-official",
    input_column_name=["text"],
    target_column_name="target",
    load_dataset_kwargs={
        "train_domains": ["hotels", "medicine"],
        "dev_domains": ["hotels", "medicine"],
        "test_domains": ["hotels", "medicine"],
        "text_cfg": "text",
    },
    output_path=".",
    config=config
)

You can also define an Advanced config with populated keyword arguments. In general, the keywords are passed to the object when constructing specific pipelines. We can identify and trace the keyword arguments to find the possible arguments that can be set in the config kwargs.

from embeddings.config.lightning_config import LightningAdvancedConfig

config = LightningAdvancedConfig(
    finetune_last_n_layers=0,
    task_train_kwargs={
        "max_epochs": 1,
        "devices": "auto",
        "accelerator": "cpu",
        "deterministic": True,
    },
    task_model_kwargs={
        "learning_rate": 5e-4,
        "use_scheduler": False,
        "optimizer": "AdamW",
        "adam_epsilon": 1e-8,
        "warmup_steps": 100,
        "weight_decay": 0.0,
    },
    datamodule_kwargs={
        "downsample_train": 0.01,
        "downsample_val": 0.01,
        "downsample_test": 0.05,
    },
    dataloader_kwargs={"num_workers": 0},
)

Available embedding models for Polish

Instead of the allegro/herbert-base-cased model, user can pass any model from HuggingFace Hub that is compatible with Transformers or with our library.

Embedding	Type	Description

Optimized pipelines

Transformers embeddings

Task	Optimized Pipeline
Lightning Text Classification	OptimizedLightingClassificationPipeline
Lightning Sequence Labeling	OptimizedLightingSequenceLabelingPipeline

Example with Text Classification

Optimized pipelines can be run via following snippet of code:

from embeddings.config.lighting_config_space import LightingTextClassificationConfigSpace
from embeddings.pipeline.lightning_hps_pipeline import OptimizedLightingClassificationPipeline

pipeline = OptimizedLightingClassificationPipeline(
    config_space=LightingTextClassificationConfigSpace(
        embedding_name_or_path="allegro/herbert-base-cased"
    ),
    dataset_name_or_path="clarin-pl/polemo2-official",
    input_column_name="text",
    target_column_name="target",
).persisting(best_params_path="best_prams.yaml", log_path="hps_log.pickle")
df, metadata = pipeline.run()

Training model with obtained parameters

After the parameters search process we can train model with best parameters found. But firstly we have to set output_path parameter, which is not automatically generated from OptimizedLightingClassificationPipeline.

metadata["output_path"] = "."

Now we are able to train the pipeline

from embeddings.pipeline.lightning_classification import LightningClassificationPipeline

pipeline = LightningClassificationPipeline(**metadata)
results = pipeline.run()

Selection of best embedding model

Instead of performing search with single embedding model we can search with multiple embedding models via passing them as list to ConfigSpace.

pipeline = OptimizedLightingClassificationPipeline(
    config_space=LightingTextClassificationConfigSpace(
        embedding_name_or_path=["allegro/herbert-base-cased", "clarin-pl/roberta-polish-kgr10"]
    ),
    dataset_name_or_path="clarin-pl/polemo2-official",
    input_column_name="text",
    target_column_name="target",
).persisting(best_params_path="best_prams.yaml", log_path="hps_log.pickle")
