i review a class of exact string backgrounds, which appear in hierarchies, where the boundary of the target space of an exact sigma model is itself the target space of another exact model. from the worldsheet viewpoint this is due to the existence of ( 1, 1 ) operators based on parafermions. from the target space side,... | arxiv:hep-th/0612243 |
many clustering algorithms are guided by certain cost functions such as the widely - used $ k $ - means cost. these algorithms divide data points into clusters with often complicated boundaries, creating difficulties in explaining the clustering decision. in a recent work, dasgupta, frost, moshkovitz, and rashtchian ( ... | arxiv:2106.15566 |
