Domain, in math, is defined as the set of all possible values that can be used as input values in a function. A simple mathematical function has a domain of all real numbers because there isn’t a number that can be put into the function and not work. An example in which the domain...
Find the domain and range of a function with Wolfram|Alpha x2+1x2-1domain At End of Start Fraction, Start numerator, ( Start Power, Start base, x , base End,Start exponent, 2 , exponent End , Power End +1) , numerator End,Start denominator, ( Start Power, Start base, x , ...
In mathematics, what distinguishes a function from a relation is thateach xvalue in afunctionhas one and onlyONE y-value. Since relation #1 has ONLY ONE y value for each x value, this relation is afunction. On the other hand, relation #2 has TWO distinct y values'a'and'c'for the s...
Computing the logarithm of zero or a negative number: In mathematics, the logarithm is not defined for zero or negative numbers. If you try to executemath.log(0)ormath.log(-5), you’ll encounter the same error. Calculating the arc cosine or arc sine of a number that’s not in the r...
Example: a simple function like f(x) = x2 can have the domain (what goes in) of just the counting numbers {1,2,3,...}, and the range will then be the set {1,4,9,...} And another function g(x) = x2 can have the domain of integers {...,-3,-2,-1,0,1,2,3,......
I'm new to using themathlibrary in Python. The purpose of this script is to show my "working out" ofCross-Entropyerror function. I have checked my parentheses and operators and cannot see anything wrong, with my noob eyes. The error occurs on the last line. ...

Codomain of f is a set that contains all the output values of the function. While all outputs must lie in Codom(f), not every number in codom(f) need to be an output value. Codomain的定义一定要跟后边的range区分开来. 我们用下面一张图来解释: 函数f:X->Y 的定义域是图中红色的部分,...
然后假设我们用binary CrossEntropy来进行优化h,那么entropy越少,d_\mathcal H(D_S, D_T)就越少,说明两个domain的数据分布在这个hypothesish空间上差距不大。 经验样本预测? 用经验误差\hat{d}来预测d,这里我没花时间研究,直接给出结论。对于任意的\delta \in (0, 1),hypothesis是d维,在至少1-\delta的...
