查询词典 unique factorization domain

When giving a new sample, DNMF makes use of the code matrix and base matrix factorized from the original dataset to initialize the factorization of new samples set.

This kind of parallel processing hugely improves the computational speed, and can change some NP problems that cannot be accomplished by classical computers, i.e., the complexity of the problems exponentially increases with the increase of bits, to P problems, i.e., the complexity of the problems polynomially increases with the increase of bits. In 1994 Peter Shor at Bell Laboratory proved that quantum computers could efficiently solve the problem of Large Number Factorization, which was the security footstone of nowaday classical cryptosystems, while none of any classical computers could implement this.

这种并行处理极大地提高了计算速度，可以把一些经典计算中无法计算的NP问题即问题的复杂度随着比特位数的增长而指数上升，变成P问题即问题的复杂度随着比特位数的增长以多项式上升。1994年，Bell实验室的Peter Shor证明量子计算机可以有效解决经典计算机所不能解决的大数因子分解问题，而这恰恰是目前经典密码的安全性基础。

Metaphor is the cognitive way to conceptualize an abstract category on the basis of the experiences in another category within a different domain, and metonymy is the cognitive way to activate one cognitive category by referring to another category within the same domain.

隐喻是人类将其某一领域的经验用来说明或理解另一类领域的一种认知方式，转喻是同一认知域内相关联的两个事物中，一个突显事物替代另一事物的认知方式。
