1 - About
Prediction probabilities are also known as:
- confidence (How confident can I be of this prediction?).
- or likelihood: (How likely is this prediction to be true?)
If you give me several pictures of cats and dogs – and then you ask me to classify a new cat photo – I should return a prediction with rather high confidence. But if you give me a photo of an ostrich and force my hand to decide if it's a cat or a dog – I better return a prediction with very low confidence. Yarin Gal
