## Limitations and bias
|
| 47 |
-
|
| 48 |
-
The following factors may degrade the model’s performance.
|
| 49 |
-
|
| 50 |
-
**Text Language**: The model was trained on Brazilian Portuguese texts, so it may not work well with Portuguese dialects.
|
| 51 |
-
|
| 52 |
-
**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.
|
| 53 |
-
|
| 54 |
-
## Trade-offs
|
| 55 |
-
|
| 56 |
-
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.
|
| 57 |
-
|
| 58 |
-
**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.
|
| 59 |
-
|
| 60 |
-
