This … WebNov 16, 2024 · It is proved that by imposing that the metric functions are the reciprocal of each other (grr = 1/gtt ), the f(Q) gravity theory reduces to the symmetric teleparallel equivalent of general relativity (plus a cosmological constant), and the metric takes the (Anti)de-Sitter-Schwarzschild form. WebIn this section, we first discuss the symmetric version of SNE (Section 3). Subsequently, we discuss the crowding problem (Section 3), and the use of heavy-tailed distributions to address this problem (Section 3). We conclude the section by describing our approach to the optimization of the t-SNE cost function (Section 3). 3 Symmetric SNE iosh catch the wave
