Patch-based vision models face challenges in accurately inferring object boundaries due to tokenization issues, prompting Lambda to explore object-centric representations through Deep Latent Particles (DLP) modeling. This approach shifts focus from image patches to learning self-supervised object representations, addressing the visual binding problem effectively in both 2D and 3D contexts. Lambda's recent work, presented at ICML 2026, demonstrates the application of DLPs in 3D scenes by decomposing real, colored 3D observations into a set of interpretable particles that encapsulate 3D position, size, and appearance. They replaced the keypoint-proposal mechanism with an appearance-aware K-means prior to improve object surface alignment and implemented a chroma loss to prevent color collapse in reconstructions. Experiments showed that these 3D particles enhance performance in various tasks compared to traditional methods, and the framework offers dense, interpretable representations that facilitate language and cross-modal integration, marking a pioneering self-supervised approach for decomposing colored 3D scenes into object-centric particles without relying on annotations or pre-trained models.
