Frequently asked questions about XLM
What is XLM and what does it do?
XLM is a PyTorch-based framework for cross-lingual language model pretraining, developed by Facebook Research. It supports monolingual and cross-lingual pretraining, including models like BERT, and is designed for tasks such as machine translation, text classification, and sentiment analysis.
Who is XLM suitable for?
XLM is ideal for researchers, engineers, and data scientists working on multilingual NLP tasks. It is particularly useful for those needing cross-lingual capabilities, such as supervised or unsupervised machine translation and cross-lingual text classification.
How do I get started with XLM?
To get started, install the Python package in editable mode using 'pip install -e .'. Ensure dependencies like PyTorch, NumPy, and fastBPE are installed. The repository provides scripts for data preparation, pretraining, and fine-tuning, along with example notebooks for demonstration.
Does XLM support multi-GPU and multi-node training?
Yes, XLM supports both multi-GPU and multi-node training, making it scalable for large datasets and complex models. The framework includes code for distributed training setups.
What tasks can I perform with XLM?
XLM supports tasks such as monolingual language model pretraining (e.g., BERT), cross-lingual language model pretraining (XLM), supervised or unsupervised machine translation, cross-lingual text classification (e.g., XNLI), and fine-tuning on GLUE benchmarks.
Are there pretrained models available in XLM?
Yes, XLM provides pretrained models, including an English-only BERT model trained with the MLM objective. The repository also includes BPE codes and vocabulary files for various languages to facilitate pretraining and fine-tuning.
