In the proposed HyperGCN model, we only train the autoencoder with reconstruction loss of the input gene expression matrix \(X\), and do not consider the VGAE loss. Both Import mode and Direct Lake models can page data in and out of memory as required, so the whole model may not be in memory at any given time. However, in order for a query to run, the data it needs must be in memory and cannot be paged out until the query has finished with it. Therefore out of all the memory consumed by a semantic model, at any given time, some of that memory is “evictable” because it isn’t in use while some of it is “non-evictable” because it is being used.

Key of lexical semantics include identifying word senses, synonyms, antonyms, hyponyms, hypernyms, and morphology.
