SHARP optimizes large-scale model training by utilizing a Smooth Hamiltonian Ascent approach to find flatter minima and improve generalization.

Apple researchers developed SHARP (Smooth Hamiltonian Ascent for Resilient Protocol) to tackle the sharpness-aware minimization challenge in deep learning. By leveraging a Hamiltonian dynamics framework, the optimizer efficiently navigates loss landscapes to locate flatter minima, which directly correlates to better test-time performance. In benchmarks against standard SGD and Adam, SHARP demonstrates superior robustness across ImageNet and various Transformer architectures while maintaining computational efficiency (reducing the overhead typically associated with second-order optimization methods).

### [Reconstructing Memories with 3D Gaussian Splatting](https://hong-kong.aitinkerers.org/talks/rsvp_zmGEdhKSUks)

The Foundation: Using 3D Gaussian Splatting (3DGS) to recreate real-world environments with hyper-realistic fidelity with PostShot. Showing the PLY file on SuperSplat also showing how ply file structure. Meta SAM 3D: Integrating Meta’s SAM 3D to isolate and create specific 3D objects. Also showing the Spatial Reasoning ability and when it fails. Apple’s SHARP: Using Apple’s SHARP via CLI to transform flat, historical photos into 3D Gaussian volumes, effectively "re-spatializing" the past. Custom code for batch processing and potentially 4D gaussian splatting creation. Marble (World Labs): Implementing Marble (World Labs) to generate synthetic 3D environments that reflects subjective imagination.
