# Model Details

xlm-mlm-100-1280 is the XLM model, which was proposed in Cross-lingual Language Model Pretraining by Guillaume Lample and Alexis Conneau, trained on Wikipedia text in 100 languages. The model is a transformer pretrained using a masked language modeling (MLM) objective.

# Uses

## Direct Use

The model is a language model. The model can be used for masked language modeling.

## Out-of-Scope Use

The model should not be used to intentionally create hostile or alienating environments for people.

# Bias, Risks, and Limitations

Significant research has explored bias and fairness issues with language models (see, e.g., Sheng et al. (2021) and Bender et al. (2021)).

## Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model.

# Training

This model is the XLM model trained on Wikipedia text in 100 languages. The preprocessing included tokenization with byte-pair-encoding. See the GitHub repo and the associated paper for further details on the training data and training procedure.

Conneau et al. (2020) report that this model has 16 layers, 1280 hidden states, 16 attention heads, and the dimension of the feed-forward layer is 1520. The vocabulary size is 200k and the total number of parameters is 570M (see Table 7).

# Evaluation

## Testing Data, Factors & Metrics

The model developers evaluated the model on the XNLI cross-lingual classification task (see the XNLI data card for more details on XNLI) using the metric of test accuracy. See the GitHub Repo for further details on the testing data, factors and metrics.

## Results

For xlm-mlm-100-1280, the test accuracy on the XNLI cross-lingual classification task in English (en), Spanish (es), German (de), Arabic (ar), Chinese (zh) and Urdu (ur) are:

Language en es de ar zh ur
83.7 76.6 73.6 67.4 71.7 62.9

# Environmental Impact

Carbon emissions can be estimated using the Machine Learning Impact calculator presented in Lacoste et al. (2019).

# Technical Specifications

Conneau et al. (2020) report that this model has 16 layers, 1280 hidden states, 16 attention heads, and the dimension of the feed-forward layer is 1520. The vocabulary size is 200k and the total number of parameters is 570M (see Table 7).
