denoising
Removing unwanted interference
Denoising is the process of removing unwanted random variation—noise—from a signal or image.
In photography and audio engineering, denoising algorithms clean up grainy photos or hissy recordings.
In machine learning, denoising autoencoders learn to reconstruct clean data from corrupted inputs: The AI model was trained using denoising techniques.
