New CANDOR measure reveals weaknesses in frozen AI encoders

Researchers have developed CANDOR, a new discordance measure designed to more accurately assess the capabilities of frozen foundation encoders. Unlike previous methods, CANDOR uses symmetric, equal-sized banks to fix its chance level at precisely 50%, correcting for biases introduced by unequal prevalence of findings. Across extensive testing on 22 encoders and 605,443 images from various domains, CANDOR revealed that while no encoder is truly blind, all exhibit weaknesses in discerning specific findings, with performance often falling below expectations.

    CANDOR: Chance-Calibrated Discordance in Frozen Foundation Encoders

    arXiv:2607.18451v1 Announce Type: cross Abstract: Frozen encoders are chosen by how well a lightweight head reads a finding from their features, not whether the geometry separates it. Nearest-neighbor discordance does, but with unequal banks the opposite-label neighbor wins on de…
