What are the two values in which the denominator is undefined in the following equation? f(x) = x/(x2 - x - 3) Determine the restricted values of y for the rational expression to be defined. \frac{2y - 3}{9y + 7} Create two different rational polynomial ...
We used logistic regression as the classification algorithm [19]. The loss function is the negative log-likelihood that is expressed by the following equation: 𝐸(𝛼)=−1𝑚∑𝑖=1𝑚⎧⎩⎨ 𝑤0𝑦𝑖log𝜎(𝛼,𝑥𝑖)+𝑤1(1−𝑦𝑖)log(1−𝜎(𝛼,𝑥𝑖))+...
As the score obtained when Equation (3) is applied should be zero, the formula is as follows: 0=𝑘·𝑛·1𝑚+𝑝·𝑛·𝑚−1𝑚0=k·n·1m+p·n·m−1m (4) Taking into account that 𝑚≠0:0=𝑘·𝑛+𝑝·𝑛·(𝑚−1)Taking into account that m≠0:0=k·n...
