+# TeenyTinyLlama-460m-IMDB
+
+TeenyTinyLlama is a series of small foundational models trained in Brazilian Portuguese.
+
+This repository contains a version of [TeenyTinyLlama-460m](https://huggingface.co/nicholasKluge/TeenyTinyLlama-460m) (`TeenyTinyLlama-460m-IMDB`) fine-tuned on the the [IMDB dataset](https://huggingface.co/datasets/christykoh/imdb_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 = "Esqueceram de mim 2 é um dos melhores filmes de natal de todos os tempos."
+
+classifier = pipeline("text-classification", model="nicholasKluge/TeenyTinyLlama-460m-IMDB")
+classifier(text)
+
+# >>> [{'label': 'POSITIVE', 'score': 0.9971244931221008}]
+```
+
+## Reproducing
+
+To reproduce the fine-tuning process, use the following code snippet:
+
+```python
+# IMDB
+! pip install transformers datasets evaluate accelerate -q
+
+import evaluate
+import numpy as np
+from datasets import load_dataset
+from transformers import AutoTokenizer, DataCollatorWithPadding
+from transformers import AutoModelForSequenceClassification, TrainingArguments, Trainer
+
+# Load the task
+dataset = load_dataset("christykoh/imdb_pt")
+
+# Create a `ModelForSequenceClassification`
+model = AutoModelForSequenceClassification.from_pretrained(
+    "nicholasKluge/TeenyTinyLlama-460m", 
+    num_labels=2, 
+    id2label={0: "NEGATIVE", 1: "POSITIVE"}, 
+    label2id={"NEGATIVE": 0, "POSITIVE": 1}
+)
+
+tokenizer = AutoTokenizer.from_pretrained("nicholasKluge/TeenyTinyLlama-460m")
+
+# 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-name-imdb"
+)
+
+# 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()
+```
