We also address a more general problem of matrix rank degeneration & non-isolated minima in the low-rank matrix optimization by using new type of regularizer which approximately enforces the or-thonormality of the learned matrix very efficiently .
 conjunction: matrix rank degeneration, non-isolated minima; feature of: matrix rank degeneration, low-rank matrix optimization; feature of: non-isolated minima, low-rank matrix optimization; used for: regularizer, low-rank matrix optimization; used for: regularizer, or-thonormality; feature of: or-thonormality, learned matrix
Given a phrase that describes the relationship between two words, extract the words and the lexical relationship between them. The output format should be "relation1: word1, word2; relation2: word3, word4". 
Option: conjunction, feature of, hyponym of, used for, part of, compare, evaluate for
