Locally Linear Embedding (LLE) and Isomap are two frameworks to process and analyze highdimensional non-linear data domains, such as time and spatial series images. These techniques allow the creation of low-dimensional embeddings of the original data that are much easier to visualize and work with than the initial, high-dimensional data. In particular, the dimensionality of such embeddings is ...

LLE Review, Volume 115 113 Introduction The OMEGA EP chirped-pulse–amplification system at LLE requires two 1.5-m large-aperture grating compressors to achieve high-energy petawatt capability.1 The current state-ofthe-art multilayer dielectric (MLD) diffraction gratings cannot meet this size requirement.2 Several institutes have explored the possibility of tiling gratings.3–6 Kessler and Cotel ...
