3D Masked Autoencoders are Robust Learners of Volumetric and Multimodal Cellular Representations for Microscopy
arXiv:2606.23964v1 Announce Type: new Abstract: Self-supervised learning in fluorescence microscopy often relies on 2D projections, despite the inherently three-dimensional nature of cells. We present a systematic comparison of 2D and 3D masked autoencoders (MAE-2D vs. MAE-3D) on volumetric microscopy data. Under matched architectures and training protocols, MAE-3D consistently outperforms 2D max-projection and slice-based variants on downstream single-cell tasks. We further align visual representations with a pretrained protein language model (ESM2) and show that cross-modal supervision yield
The continuous advancements in AI and microscopy technologies, specifically in self-supervised learning and volumetric imaging, are now converging to create more sophisticated biological analysis tools.
This development significantly enhances the ability to robustly analyze complex 3D cellular data, which is crucial for drug discovery, disease understanding, and the broader synthetic biology field.
The ability of 3D masked autoencoders to consistently outperform 2D methods means that more accurate and detailed cellular representations can be derived, shifting the paradigm for biological insights.
