T5 Base Dutch
The T5 Base Dutch model is a powerful tool for natural language processing tasks, specifically designed for the Dutch language. With 222 million parameters, it was pre-trained on a large dataset of Dutch text using a masked language modeling objective. This model is efficient, with a sequence length of 512 and a batch size of 128, allowing for fast processing of text data. It has been fine-tuned for summarization and translation tasks, achieving impressive results on evaluation metrics such as Rouge and Bleu scores. The model's performance is notable, with a samples per second rate of 45.19, making it suitable for real-world applications. While it requires fine-tuning for specific tasks, the T5 Base Dutch model is a valuable resource for those working with Dutch language data.

Comparison to Other Models
The Current Model is not the only model that has been trained on Dutch text. Let’s compare its performance to other models:
Model | Rouge1 Score | Bleu Score |
---|---|---|
Current Model | 33.38 | 45.88 |
==t5-v1.1-base-dutch-uncased== | 33.97 | 51.21 |
==t5-v1.1-base-dutch-cased== | 34.39 | 48.31 |
Fine-Tuning
The Current Model can be fine-tuned for specific tasks, such as language translation. In fact, two models, t5-small-24L-dutch-english
and t5-base-36L-dutch-english
, have been fine-tuned for both language directions on the CCMatrix dataset. The results are impressive:
Model | Source Language | Target Language | Bleu Score |
---|---|---|---|
t5-base-36L-ccmatrix-multi | English | Dutch | 56.8 |
t5-base-36L-ccmatrix-multi | Dutch | English | 62.8 |
t5-small-24L-ccmatrix-multi | English | Dutch | 57.4 |
t5-small-24L-ccmatrix-multi | Dutch | English | 63.1 |
Limitations
The Current Model has several limitations that are important to consider when using it for downstream tasks.
Limited Training Data
The model was trained on a limited dataset, which may not be representative of all possible scenarios. This can lead to biases and inaccuracies in the model’s outputs.
Lack of Common Sense
While the Current Model is good at understanding language, it sometimes lacks common sense or real-world experience. This can result in outputs that are not practical or realistic.
Inability to Reason Abstractly
The model is not capable of abstract reasoning or complex problem-solving. It is best suited for tasks that require language understanding and generation.
Format
The Current Model uses a transformer architecture, specifically designed for text-to-text tasks. This model accepts input in the form of tokenized text sequences.
Input Format
- The model expects input text to be pre-processed using a SentencePiece tokenizer.
- The tokenizer is configured with the following normalizers:
- Nmt
- NFKC
- Replace multi-space to single-space
- The model has a vocabulary size of 32,003 tokens.
Output Format
- The model generates output in the form of tokenized text sequences.
- The output can be converted back to plain text using the same SentencePiece tokenizer.
Special Requirements
- The model requires a specific sequence length of 512 tokens.
- The model uses a batch size of 128.
Example Code
Here’s an example of how to use the Current Model in Python:
import torch
from transformers import T5Tokenizer, T5ForConditionalGeneration
# Load pre-trained model and tokenizer
tokenizer = T5Tokenizer.from_pretrained('t5-base-dutch')
model = T5ForConditionalGeneration.from_pretrained('t5-base-dutch')
# Pre-process input text
input_text = "Dit is een voorbeeld zin."
inputs = tokenizer.encode_plus(input_text,
add_special_tokens=True,
max_length=512,
return_attention_mask=True,
return_tensors='pt')
# Generate output
outputs = model.generate(inputs['input_ids'],
attention_mask=inputs['attention_mask'],
max_length=512)
# Convert output to plain text
output_text = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(output_text)
