Common data quality issues in language datasets
Language datasets often contain various quality issues that can negatively impact LLM training:
- Spelling and grammatical errors can introduce noise and inconsistencies in the learned representations.
- Inconsistent formatting can lead to unnecessary complexity in the model’s learned patterns.
- Redundant data can cause models to overfit to specific patterns or bias present in the duplicates.
- Irrelevant or low-quality content can dilute the useful information in the dataset.
- Incomplete or truncated sentences can lead to models learning incomplete language structures.
- Code-switching and mixed languages can confuse models trained for specific languages.
- Personally identifiable information (PII) raises privacy concerns and can lead to the memorization of sensitive data.
To detect these issues, we can use various Python libraries and techniques. Here’s an example using spaCy for basic text quality...
