dougtrajano/toxic-comment-classification
Toxic Comment Classification is a model that detects if the text is toxic or not.
This BERT model is a fine-tuned version of neuralmind/bert-base-portuguese-cased on the OLID-BR dataset.
Overview
Input: Text in Brazilian Portuguese
Output: Binary classification (toxic or not toxic)
Usage
from transformers import AutoTokenizer, AutoModelForSequenceClassification
tokenizer = AutoTokenizer.from_pretrained("dougtrajano/toxic-comment-classification")
model = AutoModelForSequenceClassification.from_pretrained("dougtrajano/toxic-comment-classification")
Limitations and bias
The following factors may degrade the model’s performance.
Text Language: The model was trained on Brazilian Portuguese texts, so it may not work well with Portuguese dialects.
Text Origin: The model was trained on texts from social media and a few texts from other sources, so it may not work well on other types of texts.
Trade-offs
Sometimes models exhibit performance issues under particular circumstances. In this section, we'll discuss situations in which you might discover that the model performs less than optimally, and should plan accordingly.
Text Length: The model was fine-tuned on texts with a word count between 1 and 178 words (average of 18 words). It may give poor results on texts with a word count outside this range.
Performance
The model was evaluated on the test set of the OLID-BR dataset.
