AI BriefingHALO-Loss Encourages Neural Networks to Refuse to Answer
·2026.04.14 14:45
Key point
Research has been released on training neural networks to abstain from answering uncertain questions through HALO-Loss.
Details
A new loss function called HALO-Loss has been proposed to encourage neural networks to answer "I don't know" (Abstain) in uncertain situations, instead of giving incorrect predictions.
This research focuses on training models to recognize their own uncertainty and withhold answers, in order to increase model reliability and prevent incorrect information.
