In the world of Natural Language Processing, transforming structured data like numbers and dates into readable text is pivotal, especially for Text-to-Speech systems. Here, we’ll delve into the mbart-large-50-verbalization model—a specialized tool fine-tuned for verbalizing Ukrainian text. This guide will walk you through its usage, from setup to running the model effectively. Let’s get started!
Understanding the Model
The mbart-large-50-verbalization model is based on the widely recognized facebook/mbart-large-50 architecture. Think of this model as a specialized translator, converting structured language into a fluent, human-like narrative. It was fine-tuned using a large dataset of news content, which helps it understand the nuances of verbalizing text in Ukrainian.
Setting Up the Environment
To begin utilizing this model, ensure you have the necessary libraries installed. You will need:
Loading the Dataset
Begin by loading the dataset using the code below. This dataset is critical as it comprises the 457,610 sentences from the Ubertext news dataset:
dataset = load_dataset("skypro1111/ubertext-2-news-verbalized")Preprocessing the Data
Next, we want to prepare our data for the model. Think of preprocessing like preparing ingredients before cooking—making sure everything is in the right form and size:
def preprocess_data(examples):
model_inputs = tokenizer(examples["inputs"], max_length=1024, truncation=True, padding="max_length")
with tokenizer.as_target_tokenizer():
labels = tokenizer(examples["labels"], max_length=1024, truncation=True, padding="max_length")
model_inputs["labels"] = labels["input_ids"]
return model_inputs
datasets = datasets.map(preprocess_data, batched=True)Training the Model
After preprocessing, it’s time to train the model. This process fine-tunes how it verbalizes text:
trainer = Trainer(
model=model,
args=training_args,
train_dataset=datasets["train"],
eval_dataset=datasets["test"],
)
trainer.train()
trainer.save_model(f"saved_models/{model_name}-verbalization")Using the Model
Once the model is trained, you can utilize it to verbalize text. Here’s how to input a sentence and get the transformed output:
input_text = "Цей додаток вийде 15.06.2025."
encoded_input = tokenizer(input_text, return_tensors="pt", padding=True, truncation=True, max_length=1024).to(device)
output_ids = model.generate(**encoded_input, max_length=1024, num_beams=5, early_stopping=True)
output_text = tokenizer.decode(output_ids[0], skip_special_tokens=True)
print(output_text)Troubleshooting
While working with models, you might encounter a few hiccups. Here are some common issues and their solutions:
- Out of Memory Error: If you’re using a GPU and run out of memory, consider reducing the batch size in
TrainingArguments. - Slow Performance: Make sure that CUDA is properly installed if you’re trying to utilize GPU processing.
- Tokenization Issues: Ensure that the input format matches the expected format for the tokenizer.
