Model description

This model is a fine-tuned version of distilbert-base-multilingual-cased for text classification tasks. The model has been adapted using LoRA (Low-Rank Adaptation) to efficiently train on the target dataset with fewer parameters, allowing for better performance with less computational resources.

Intended uses & limitations

The model was trained and evaluated on the Russian Language news dataset, which consists of news texts labeled as positive, negative or neutral. The dataset is divided into training and test sets for evaluation purposes.

Intended Use

This model is intended for text classification tasks, particularly multilabel sentiment analysis. It can be fine-tuned further for other classification tasks by using appropriate datasets and modifying the number of labels.

Limitations and Risks

Bias: The model may inherit biases present in the training data.
Generalization: Performance may vary on datasets with different distributions from the training data.
Resource Usage: Although more efficient than larger models, fine-tuning and inference still require significant computational resources.

Training and evaluation data

The model was evaluated using the following metrics:

Accuracy: Measures the fraction of correct predictions.
F1 Score: Harmonic mean of precision and recall.
Precision: Proportion of positive identifications that are actually correct.
Recall: Proportion of actual positives that are correctly identified.

Training procedure

Preprocessing

Tokenization: The text data was tokenized using the DistilBertTokenizer with a maximum length of 512 tokens.
Padding and Truncation: Applied to ensure uniform input size.

Training hyperparameters

The following hyperparameters were used during training:

learning_rate: 0.0009143508688456378
train_batch_size: 32
eval_batch_size: 32
seed: 42
optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
lr_scheduler_type: linear
num_epochs: 7

How to Use

from transformers import DistilBertTokenizer, DistilBertForSequenceClassification, Trainer, TrainingArguments
from peft import PeftConfig, PeftModel

# Load the tokenizer and model
tokenizer = DistilBertTokenizer.from_pretrained('distilbert-base-multilingual-cased')
model_id = 'pyteach237/multilabel_lora_distilbert_runews_classifier_tuned'
config = PeftConfig.from_pretrained(model_id)

# Define the model with LoRA
model = DistilBertForSequenceClassification.from_pretrained(
    config.base_model_name_or_path,
    num_labels=3
)
model = PeftModel.from_pretrained(model, model_id, config=config)

text = "Your text here :)"

# Tokenize input
inputs = tokenizer(text, return_tensors="pt", truncation=True, padding='max_length', max_length=512)

# Make predictions
outputs = model(**inputs)
predictions = outputs.logits.argmax(dim=-1)

# Convert predictions to labels
labels = ['negative', 'neutral', 'positive']
predicted_label = labels[predictions.item()]
print(f'Predicted label: {predicted_label}')
