# TeenyTinyLlama-160m-AgNews
TeenyTinyLlama is a pair of small foundational models trained in Brazilian Portuguese.
This repository contains a version of [TeenyTinyLlama-160m](https://huggingface.co/nicholasKluge/TeenyTinyLlama-160m) (`TeenyTinyLlama-160m-AgNews`) fine-tuned on the [AgNews dataset](https://huggingface.co/datasets/maritaca-ai/ag_news_pt).
## Details
- **Number of Epochs:** 3
- **Batch size:** 16
- **Optimizer:** `torch.optim.AdamW` (learning_rate = 4e-5, epsilon = 1e-8)
- **GPU:** 1 NVIDIA A100-SXM4-40GB
## Usage
Using `transformers.pipeline`:
```python
from transformers import pipeline
text = "Quando falamos de Inteligência Artificial, hoje em dia existem já vários sistemas que começam a ganhar popularidade,\
embora nenhum seja ainda tão conhecido como o ChatGPT da OpenAI."
classifier = pipeline("text-classification", model="nicholasKluge/TeenyTinyLlama-160m-AgNews")
classifier(text)
# >>> [{'label': 'TECNOLOGIA', 'score': 0.9997298121452332}]
```
## Reproducing
To reproduce the fine-tuning process, use the following code snippet:
```python
# AgNews
!pip install transformers datasets evaluate accelerate -q
import evaluate
import numpy as np
from datasets import load_dataset, Dataset, DatasetDict
from transformers import AutoTokenizer, DataCollatorWithPadding
from transformers import AutoModelForSequenceClassification, TrainingArguments, Trainer
# Load the task
dataset = load_dataset("maritaca-ai/ag_news_pt")
# Create a `ModelForSequenceClassification`
model = AutoModelForSequenceClassification.from_pretrained(
"nicholasKluge/TeenyTinyLlama-160m",
num_labels=4,
id2label={0: "MUNDO", 1: "ESPORTES", 2: "NEGÓCIOS", 3: "TECNOLOGIA"},
label2id={"MUNDO": 0, "ESPORTES": 1, "NEGÓCIOS": 2, "TECNOLOGIA": 3}
)
tokenizer = AutoTokenizer.from_pretrained("nicholasKluge/TeenyTinyLlama-160m")
# Format the dataset
train = dataset['train'].to_pandas()
train["text"] = train["title"] + "\n\n" + train["text"]
train.label = train.label.astype(int)
train = Dataset.from_pandas(train)
test = dataset['test'].to_pandas()
test["text"] = test["title"] + "\n\n" + test["text"]
test.label = test.label.astype(int)
test = Dataset.from_pandas(test)
dataset = DatasetDict({
"train": train,
"test": test
})
# Preprocess the dataset
def preprocess_function(examples):
return tokenizer(examples["text"], truncation=True, max_length=256)
dataset_tokenized = dataset.map(preprocess_function, batched=True)
# Create a simple data collactor
data_collator = DataCollatorWithPadding(tokenizer=tokenizer)
# Use accuracy as an evaluation metric
accuracy = evaluate.load("accuracy")
# Function to compute accuracy
def compute_metrics(eval_pred):
predictions, labels = eval_pred
predictions = np.argmax(predictions, axis=1)
return accuracy.compute(predictions=predictions, references=labels)
# Define training arguments
training_args = TrainingArguments(
output_dir="checkpoints",
learning_rate=4e-5,
per_device_train_batch_size=16,
per_device_eval_batch_size=16,
num_train_epochs=3,
weight_decay=0.01,
evaluation_strategy="epoch",
save_strategy="epoch",
load_best_model_at_end=True,
push_to_hub=True,
hub_token="your_token_here",
hub_model_id="username/model-ID",
)
# Define the Trainer
trainer = Trainer(
model=model,
args=training_args,
train_dataset=dataset_tokenized["train"],
eval_dataset=dataset_tokenized["test"],
tokenizer=tokenizer,
data_collator=data_collator,
compute_metrics=compute_metrics,
)
# Train!
trainer.train()
```
## Fine-Tuning Comparisons
To further evaluate the downstream capabilities of our models, we decided to employ a basic fine-tuning procedure for our TTL pair on a subset of tasks from the Poeta benchmark. We apply the same procedure for comparison purposes on both [BERTimbau](https://huggingface.co/neuralmind/bert-base-portuguese-cased) models, given that they are also LLM trained from scratch in Brazilian Portuguese and have a similar size range to our models. We used these comparisons to assess if our pre-training runs produced LLM capable of producing good results ("good" here means "close to BERTimbau") when utilized for downstream applications.
| Models | IMDB | FaQuAD-NLI | HateBr | Assin2 | AgNews | Average |
|-----------------|-----------|------------|-----------|-----------|-----------|---------|
| BERTimbau-large | **93.58** | 92.26 | 91.57 | **88.97** | 94.11 | 92.10 |
| BERTimbau-small | 92.22 | **93.07** | 91.28 | 87.45 | 94.19 | 91.64 |
| **TTL-460m** | 91.64 | 91.18 | **92.28** | 86.43 | **94.42** | 91.19 |
| **TTL-160m** | 91.14 | 90.00 | 90.71 | 85.78 | 94.05 | 90.34 |
All the shown results are the higher accuracy scores achieved on the respective task test sets after fine-tuning the models on the training sets. All fine-tuning runs used the same hyperparameters, and the code implementation can be found in the [model cards](https://huggingface.co/nicholasKluge/TeenyTinyLlama-460m-HateBR) of our fine-tuned models.
