This chapter examines the techniques for mimicking a statistical distribution using computer-generated random numbers. Which of the following assertions suggests that a computer is capable of generating really random numbers that pass all standards for randomness? Is it beneficial to study random number generators and their implementation strategies?
Correct answer will be upvoted else downvoted. Computer science. Allow us to signify by d(n) the amount of all divisors of the number n, for example d(n)=∑k|nk. For instance, d(1)=1, d(4)=1+2+4=7, d(6)=1+2+3+6=12. For a given number c, track down the base n to such an extent that d(n)=c. Input The principal line contains one integer t (1≤t≤104). Then, at that point, t experiments follow. Each experiment is characterized by one integer c (1≤c≤107). Output For each experiment, output: "- 1" in case there is no such n that d(n)=c; n, in any case.

Computer Science A way to avoid overfitting in Deep Neural Networks is to add an additional term R to the loss function L (for example L can be the cross entropy loss) as follows: L(w) + λR(w). (1) You know that one choice for R is the L2 norm, i.e. R(w) = ||w||2 2 . One friend of yours from the School of Maths told you however that there’s no need to use squares (i.e. powers of two) and that you can achieve the same effect by using absolute values, i.e. the L1 norm: R(w) = ||w||1. Would you agree with him? i.e. is the use of the L2 norm equivalent to using the L1 norm for regularization purposes? Justify your answer

As we've seen previously, the world population data spans from 1960 to 2017. We'd like to build a predictive model that can give us the best guess at what the world population in a given year was. However, as a slight twist this time, we want to compute this estimate for only countries within a given income group. First, however, we need to organise our data such that the sklearn's RandomForestRegressor class can train on our data. To do this, we will write a function that takes as input an income group and return a 2-d numpy array that contains the year and the measured population. Function Specifications: Should take a str argument, called income_group_name as input and return a numpy array type as output. Set the default argument of income_group_name to equal 'Low income'. If the specified value of income_group_name does not exist, the function must raise a ValueError. The array should only have two columns containing the year and the population, in other words, it should have a…
