Researchers have discovered that denoising deep neural networks, when trained on natural images, develop internal representations sensitive to human perceptual illusions. These representations were found in specific layers and channels across various architectures, with the denoising objective proving more influential than the architecture itself. While these internal activations correlate with a psychophysical model of human brightness perception and scale with illusion strength, injecting them into the generation pipeline did not produce observable output changes, leading the researchers to term them "perceptual phantoms." AI
IMPACT Reveals that AI models can develop internal representations of perceptual phenomena, even if these are not reflected in output, suggesting a deeper understanding of internal model workings.
