CosmicNet II: Emulating extended cosmologies with efficient and accurate neural networks
Sven Günther, Julien Lesgourgues, Georgios Samaras +4
In modern analysis pipelines, Einstein-Boltzmann Solvers (EBSs) are an invaluable tool for obtaining CMB and matter power spectra. To accelerate the computation of these observable…
Practical linear-space Approximate Near Neighbors in high dimension
Georgia Avarikioti, Ioannis Z. Emiris, Ioannis Psarros +1
The -approximate Near Neighbor problem in high dimensional spaces has been mainly addressed by Locality Sensitive Hashing (LSH), which offers polynomial dependence on the dimens…
High-dimensional approximate nearest neighbor: k-d Generalized Randomized Forests
Yannis Avrithis, Ioannis Z. Emiris, Georgios Samaras
We propose a new data-structure, the generalized randomized kd forest, or kgeraf, for approximate nearest neighbor searching in high dimensions. In particular, we introduce new ran…
