How to Use IsRoBERTa: The Groundbreaking Icelandic Language Model

May 20, 2021

Welcome to the world of natural language processing where groundbreaking advancements are surfacing every day. Today, we’re going to dive deep into IsRoBERTa, the first-ever transformer language model specifically designed for the Icelandic language. Using the OSCAR corpus as its training data, IsRoBERTa is an impressive leap into the realm of AI.

Overview of IsRoBERTa

Language: Icelandic

Code: Visit here

Hyperparameters

per_device_train_batch_size = 48
n_epochs = 1
vocab_size = 52,000
max_position_embeddings = 514
num_attention_heads = 12
num_hidden_layers = 6
type_vocab_size = 1
learning_rate = 0.00005

How to Use IsRoBERTa

To leverage the capabilities of IsRoBERTa, you’ll need to implement a few lines of Python code using the Transformers library. Let’s draw an analogy here: think of IsRoBERTa like a well-trained Icelandic tour guide. If you say a few words to the guide (the model), it will fill in the gaps of your knowledge about Icelandic words and phrases (the sentences) beautifully.

Here’s how you can tap into this language model:

python
from transformers import pipeline, AutoTokenizer, AutoModelWithLMHead

model_name = "neurocode/IsRoBERTa"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelWithLMHead.from_pretrained(model_name)

fill_mask = pipeline(
    "fill-mask",
    model=model,
    tokenizer=tokenizer
)

result = fill_mask("Hann fór út að [MASK].")

Understanding the Code

In our analogy, the first lines import the necessary tools, akin to packing your gear before heading out for a journey. The model is initialized, and the fill_mask function is like chatting with our knowledgeable guide. When you present a partially finished sentence (say, “Hann fór út að [MASK].”), the guide will suggest various ways to complete that thought, offering the top predictions and their confidence scores, just as a guide would suggest places to visit based on your interests.

Troubleshooting Issues

If you encounter issues while using IsRoBERTa, consider the following troubleshooting tips:

Ensure you have the latest version of the Transformers library installed.
Verify that your infrastructure has adequate resources to run the model. The Nvidia K80 is recommended.
If your model fails to load, double-check the model name, ensuring it’s spelled correctly.
For import errors, make sure all required packages are installed in your Python environment.
