# RoBERTa Pretrained on Smaller Datasets
|
| 2 |
+
|
| 3 |
+
We pretrain RoBERTa on smaller datasets (1M, 10M, 100M, 1B tokens). We release 3 models with lowest perplexities for each pretraining data size out of 25 runs (or 10 in the case of 1B tokens). The pretraining data reproduces that of BERT: We combine English Wikipedia and a reproduction of BookCorpus using texts from smashwords in a ratio of approximately 3:1.

The hyperparameters corresponding to model sizes mentioned above are as follows:
|

|
| 26 |

| MED-SMALL | 6 | 8 | 512 | 2048 | 45M |
|
| 30 |
+
|
| 31 |
+
(AH = number of attention heads; HS = hidden size; FFN = feedforward network dimension; P = number of parameters.)
|
| 32 |
+
|
| 33 |
+
For other hyperparameters, we select:
|
| 34 |
+
- Peak Learning rate: 5e-4
|
| 35 |
+
- Warmup Steps: 6% of max steps
|
| 36 |
+
- Dropout: 0.1
