+ # Model Details
26
+
27
+ The XLM model was proposed in [Cross-lingual Language Model Pretraining](https://arxiv.org/abs/1901.07291) by Guillaume Lample, Alexis Conneau. xlm-mlm-enro-1024 is a transformer pretrained using a masked language modeling (MLM) objective for English-Romanian. This model uses language embeddings to specify the language used at inference. See the [Hugging Face Multilingual Models for Inference docs](https://huggingface.co/docs/transformers/v4.20.1/en/multilingual#xlm-with-language-embeddings) for further details.

41
+ # Uses
42
+
43
+ ## Direct Use
44
+
45
+ The model is a language model. The model can be used for masked language modeling.
46
+
47
+ ## Downstream Use
48
+
49
+ To learn more about this task and potential downstream uses, see the Hugging Face [fill mask docs](https://huggingface.co/tasks/fill-mask) and the [Hugging Face Multilingual Models for Inference](https://huggingface.co/docs/transformers/v4.20.1/en/multilingual#xlm-with-language-embeddings) docs.
50
+
51
+ ## Out-of-Scope Use
52
+
53
+ The model should not be used to intentionally create hostile or alienating environments for people.
54
+
55
+ # Bias, Risks, and Limitations
56
+
57
+ Significant research has explored bias and fairness issues with language models (see, e.g., [Sheng et al. (2021)](https://aclanthology.org/2021.acl-long.330.pdf) and [Bender et al. (2021)](https://dl.acm.org/doi/pdf/10.1145/3442188.3445922)).
58
+
59
+ ## Recommendations
60
+
61
+ Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model.
62
+
63
+ # Training
64
+
65
+ The model developers write:
66
+
67
+ > In all experiments, we use a Transformer architecture with 1024 hidden units, 8 heads, GELU activations (Hendrycks and Gimpel, 2016), a dropout rate of 0.1 and learned positional embeddings. We train our models with the Adam op- timizer (Kingma and Ba, 2014), a linear warm- up (Vaswani et al., 2017) and learning rates varying from 10^−4 to 5.10^−4.
68
+
69
+ See the [associated paper](https://arxiv.org/pdf/1901.07291.pdf) for links, citations, and further details on the training data and training procedure.
70
+
71
+ The model developers also write that:
72
+
73
+ > If you use these models, you should use the same data preprocessing / BPE codes to preprocess your data.
74
+
75
+ See the associated [GitHub Repo](https://github.com/facebookresearch/XLM#ii-cross-lingual-language-model-pretraining-xlm) for further details.
76
+
77
+ # Evaluation
78
+
79
+ ## Testing Data, Factors & Metrics
80
+
81
+ The model developers evaluated the model on the [WMT'16 English-Romanian](https://huggingface.co/datasets/wmt16) dataset using the [BLEU metric](https://huggingface.co/spaces/evaluate-metric/bleu). See the [associated paper](https://arxiv.org/pdf/1901.07291.pdf) for further details on the testing data, factors and metrics.
82
+
83
+ ## Results
84
+
85
+ For xlm-mlm-enro-1024 results, see Tables 1-3 of the [associated paper](https://arxiv.org/pdf/1901.07291.pdf).
86
+
87
+ # Environmental Impact
88
+
89
+ Carbon emissions can be estimated using the [Machine Learning Impact calculator](https://mlco2.github.io/impact#compute) presented in [Lacoste et al. (2019)](https://arxiv.org/abs/1910.09700).

97
+ # Technical Specifications
98
+
99
+ The model developers write:
100
+
101
+ > We implement all our models in PyTorch (Paszke et al., 2017), and train them on 64 Volta GPUs for the language modeling tasks, and 8 GPUs for the MT tasks. We use float16 operations to speed up training and to reduce the memory usage of our models.
