Cauchy-Schwarz inequality(柯西-施瓦茨不等式) 描述:connecting the dot product of two vectors and their norms :|x^{T}y|\leq ||x||_{2} ||y||_{2}(Equality holds if and only if x and y are linearly dependent) Local and global minima(局部和全局极小值) global minimum:A \ point\ x^...
This protocol makes cycles involving locks, and therefore deadlock, impossible. If this strategy does not work (can't find a set of levels), it is likely that the lock-taking behavior of the program is so input-dependent that it is impossible to guarantee that deadlock can not happen in...

for are linearly dependent, where the is in the coordinate position associated to . One way in which this can occur is if one of the gradient vectors vanish identically. This occurs at precisely points, when is equal to for some , and one has for all (so in particular ). Let us refer...
We chose to (partially) replicate CV because that is a comprehensive study on entrepreneurs’ satisfaction with a large sample, and including many kinds of independent and three dependent variables. That provides a good platform to replicate a variety of targets, so that we can quickly learn ...
What do we mean when we say that two functions y1(x) and y2(x) are linearly dependent? What are vertical and horizontal reflections with functions? Which of the twelve basic functions are their own inverses...
The variance decreases linearly: Exercise 2 Establish the virial identity As the variance (which is proportional to ) cannot become negative, this identity shows that “finite time blowup” must occur – that the zeroes must collide at or before the time . Exercise 3 Show that the Stieltj...
How a flow indicator works is dependent on its manner of providing an indication. In most instances, something is moved by the flow or a sight glass is provided to observe the flow. For indicators with devices in them, the flow moves a ball, spins a paddle, flaps, or chains. Flow ...
Well, when things are related, we say that they are linearly dependent. In other words, they fit well into a straight regression line that passes through many data points. In the incidence of multicollinearity, it is difficult to come up with reliable estimates of individual coefficients for ...
Blockchain technology achieves decentralized security and trust in several ways. To begin with, new blocks are always stored linearly and chronologically. That is, they are always added to the “end” of the blockchain. After a block has been added to the end of the blockchain, previous bloc...
