Hello, Reader.

In machine learning – the type of AI that teaches computers to learn from examples – not all data is created equal.

“Hurtful data,” be it mislabeled, misleading, or biased, can degrade AI models. That’s like a photo of a cat being labeled “dog.” Other data is “useless” because it is repetitive, low quality, or adds no meaningful new information.

If the examples are wrong, the model learns the wrong patterns.
