Training data, explained simply
An AI is only as good as what it learned from. If the examples are poor, the answers can be poor too.
Chat models learn from huge piles of text. Image models learn from pictures paired with descriptions.
Training data can raise questions about copyright, privacy and bias, so people care a lot about where it comes from.
On ITG Now, our AI news stories sometimes cover debates about what data models are trained on.
