SpecMRL: Redesign Matryoshka Representation Learning within Parametric Spectrum

Key points

• To address this, we propose SpecMRL, which reorganizes the feature space to enable more effective prefix readout.1
• Specifically, we extend MRL with a parameter-derived spectral basis organized with feature importance.1
• SpecMRL otherwise follows standard MRL, with prefix readout performed in the learned spectral space.1
• These results suggest that the learned spectral basis better prioritizes informative directions, enabling more effective representation compression.1

  Matryoshka Representation Learning (MRL) is designed to support flexible representation sizes by jointly optimizing nested prefixes.

  To address this, we propose SpecMRL, which reorganizes the feature space to enable more effective prefix readout.
