The main idea is to decorrelate data .这句子里decorrelate是什么意思呢?

"Decorrelate" 与 "correlate/correlation" 意思的相反:"The main idea is to decorrelate data"=主要的目的是除去数据的关连.
1.To establish or demonstrate as having a correlation:例句:"correlated drug abuse and crime."
2.A causal,complementary,parallel,or reciprocal relationship,especially a structural,functional,or qualitative correspondence between two comparable entities:例句 "a correlation between drug abuse and crime."
3.Statistics The simultaneous change in value of two numerically valued random variables:例句:the positive correlation between cigarette smoking and the incidence of lung cancer; the negative correlation between age and normal vision.

使分离，将。。。分开的意思。
correlate是相关性，de应该是否定前缀。 用这种方法改的这个词。实际没有decorrelate这个词。
correlate的反义词应该是dissociate。而不是decorrelate。是不是句子本身有问题。
