- A police academy has just brought in a batch of new recruits. All recruits are given an aptitude test and a fitness test. Suppose a researcher wants to know if there is a significant difference in aptitude scores based on a recruits’ fitness level. Recruits are ranked on a scale of 1 – 3 for fitness (1 = lowest fitness category, 3 = highest fitness category). Using “ApScore” as your dependent variable and “FitGroup” as your independent variable, conduct a One-Way, Between Subjects, ANOVA, at α = 0.05, to see if there is a significant difference on the aptitude test between fitness groups. Identify the correct values for dfbetween and dfwithin A. dfbetween = 7 dfwithin = 7 B. dfbetween = 13 dfwithin = 2 C. dfbetween = 2 dfwithin = 13 D. dfbetween = 2 dfwithin = 2Correct answer will be upvoted else Multiple Downvoted. Computer science. You are given an integer n (n>1). Your assignment is to find a succession of integers a1,a2,… ,ak with the end goal that: every simulated intelligence is completely more prominent than 1; a1⋅a2⋅… ⋅ak=n (I. e. the result of this grouping is n); ai+1 is separable by simulated intelligence for every I from 1 to k−1; k is the most extreme conceivable (I. e. the length of this grouping is the greatest conceivable). In case there are a few such groupings, any of them is adequate. It tends to be demonstrated that somewhere around one substantial grouping consistently exists for any integer n>1. You need to answer t autonomous experiments. Input The primary line of the input contains one integer t (1≤t≤5000) — the number of experiments. Then, at that point, t experiments follow. The main line of the experiment contains one integer n (2≤n≤1010). It is ensured that the amount of n…Decision Tree PART 2: Using following columns build a model to predict the ff person would survive or not, • Pclass• Sex• Age 1.

Predicting tomorrow’s humidity Predicting the winner in a competition Predicting the price of a stock Predicting the vote counts of candidates in an electionV1 Implement a multilayer perceptron based neural network (two hidden layers) for 3-class classification. Both holdout (70, 10, and 20%) and 5-fold cross-validation can be used to evaluate the accuracy (both overall and individual accuracy). You can select the number of hidden neurons of each hidden layer and other MLP parameters using grid-search method. The dataset (use any input file, or I can send separately) contains 7 features and the last column is the output (class labels). Packages such as tensorflow, keras, Scikitlearn etc are not allowed
- Subject: Machine Learning Question Number 5 : What are Ensemble Algorithms? Write an algorithm for BOOSTING method. Assume that two individuals offer to sell you their predictive models M1 and M2. The confusion matrices produced by each model are as follows. What is the accuracy of each model? Assuming that precision is of paramount importance in your application, which of the two models would you buy? Why?You are given a dataset of continuous numerical features with a categorical target class. There is not any missing data or outliers. Which algorithm would you use to create a model? K-means clustering Logistic regression Decision Tree Linear regressionIn the context of evolutionary computing the goal function is known as the fitnessfunction and the problem is to maximize it. The typical formulation has to be changedin a simple way.min f (x) = − max[− f (x)] (4.9)Another requirement is that the goal function is positive.Phenotype evolution treats x as a phenotype and the goal function as the fitnessfunction. The typical framework for the method is as follows:
- Question 47.Random forests are one of the most famous machine learning methods. They are easy to understand,easy to implement and reach good prediction performances even without a hyper-parameter tuning. Which of thefollowing statements on random forest are correct?a) The prediction of a classification forest is made by a majority vote of the trees’ predictions.b) The prediction of a regression forest is the median of the tree predictions.c) Each single tree in the forest uses only a part of the data available.d) The training time of a random forest scales linear with the number of trees used.In this section we create the model object and define the loss function and optimizer. For the loss function use nn.CrossEntropyLoss() instead of the mean-squared loss done in class. Use the same optimizer as in class. learning_rate = 0.001 num_epochs = 5 device = torch.device("cuda:0" if torch.cuda.is_available() else "cpu") #this is to use gpu if available # **create your neural net model here, call the variable 'model'** # ** complete following lines of code to define loss function and optimizer #criterion = **complete this** #optimizer = **complete this**Question 18 Vis Which method is usually used for developing decision trees?
