If you are venturing into the world of natural language processing (NLP) and looking to classify text data in Brazilian Portuguese, you’re in luck! In this blog, we will guide you through the process of using the AutoTrain feature from Hugging Face Transformers to create a binary classification model. This model will help you classify Brazilian Portuguese tweets as toxic or non-toxic.

Understanding the Basics

Before we dive into the implementation, let’s clarify some fundamental concepts. Imagine you’re a coach of a soccer team. You train your team (the model) using various drills (the dataset) to prepare them for a match (the classification task). The goal is to predict the outcome of a game based on the training they received. Similarly, we will be training our model to make predictions about tweet toxicity based on the data it’s been fed.

Step-by-Step Guide

1. Model Information

• Model ID: 2489776826
• Base Model: bert-base-portuguese-cased
• Model Size: 416MB
• Parameters: 109M
• CO2 Emissions: 1.7788 grams

2. Validation Metrics

• Accuracy: 0.815
• F1 Score: 0.793
• AUC: 0.895

3. Accessing the Model

You can access the model using cURL or Python API. Below is how you can use both methods:

Using cURL

To use cURL, run the following command in your terminal:

$ curl -X POST -H "Authorization: Bearer YOUR_API_KEY" -H "Content-Type: application/json" -d '{"inputs": "I love AutoTrain"}' https://api-inference.huggingface.com/models/alexandreteles/autotrain-told_br_binary_sm_bertimbau-2489776826

Using Python API

If you prefer using Python, here is a simple code snippet:

from transformers import AutoModelForSequenceClassification, AutoTokenizer

model = AutoModelForSequenceClassification.from_pretrained('alexandreteles/autotrain-told_br_binary_sm_bertimbau-2489776826', use_auth_token=True)
tokenizer = AutoTokenizer.from_pretrained('alexandreteles/autotrain-told_br_binary_sm_bertimbau-2489776826', use_auth_token=True)

inputs = tokenizer("I love AutoTrain", return_tensors='pt')
outputs = model(**inputs)

Troubleshooting Tips

While executing the steps above, you may come across some hiccups. Below are some common issues and their solutions:

• Issue: Authentication errors when using the API.
  Solution: Ensure that you have the correct API key and that you’re using it in the cURL or Python code.
• Issue: Errors related to input data formatting.
  Solution: Double-check the data format, ensuring it matches the required JSON structure.
• Issue: Model not loading correctly.
  Solution: Verify the model ID you’re using and that you are connected to the internet.
