## Dutch T5 Models
|
| 80 |
+
|
| 81 |
+
Three types of [Dutch T5 models have been trained (blog)](https://huggingface.co/spaces/yhavinga/pre-training-dutch-t5-models).
|
| 82 |
+
`t5-base-dutch` is the only model with an original T5 config.
|
| 83 |
The other model types t5-v1.1 and t5-eff have `gated-relu` instead of `relu` as activation function,
|
| 84 |
and trained with a drop-out of `0.0` unless training would diverge (`t5-v1.1-large-dutch-cased`).
|
| 85 |
+
The T5-eff models are models that differ in their number of layers. The table will list
|
| 86 |
+
the several dimensions of these models. Not all t5-eff models are efficient, the best example being the inefficient
|
| 87 |
+
`t5-xl-4L-dutch-english-cased`.

|
| 114 |
+
Most models from the list above have been fine-tuned for summarization and translation.
|
| 115 |

The figure below shows the evaluation scores, where the x-axis shows the translation Bleu score (higher is better)
|
| 116 |
+
and y-axis the summarization Rouge1 translation score (higher is better).
|
| 117 |
+
Point size is proportional to the model size. Models with faster inference speed are green, slower inference speed is
|
| 118 |
+
plotted as bleu.

Note that the amount of training data is limited to a fraction of the total dataset sizes, therefore the scores
|
| 137 |
+
below can only be used to compare the 'transfer-learning' strength. The fine-tuned checkpoints for this evaluation
|
| 138 |
+
are not saved, since they were trained for comparison of pre-trained models only.
|
| 139 |

The numbers for summarization are the Rouge scores on 1000 documents from the test split.

The models below have been evaluated for English to Dutch translation.
|
| 151 |
+
Note that the first four models are pre-trained on Dutch only. That they still perform adequate is probably because
|
| 152 |
+
the translation direction is English to Dutch.
|
| 153 |
+
The numbers reported are the Bleu scores on 1000 documents from the test split.

## Translation models
|
| 167 |
|
| 168 |
+
The models `t5-small-24L-dutch-english` and `t5-base-36L-dutch-english` have been fine-tuned for both language
|
| 169 |
+
directions on the first 25M samples from CCMatrix, giving a total of 50M training samples.
|
| 170 |
+
Evaluation is performed on out-of-sample CCMatrix and also on Tatoeba and Opus Books.
|
| 171 |
+
The `_bp` columns list the *brevity penalty*. The `avg_bleu` score is the bleu score
|
| 172 |
+
averaged over all three evaluation datasets. The best scores displayed in bold for both translation directions.

This project would not have been possible without compute generously provided by Google through the

[TPU Research Cloud](https://sites.research.google/trc/). The HuggingFace 🤗 ecosystem was instrumental in all parts

of the training. Weights & Biases made it possible to keep track of many training sessions
|
| 204 |

and orchestrate hyper-parameter sweeps with insightful visualizations.
