- A deck of cards contains 52 cards with four suits: club, diamond, heart and spade ranging in values from 2, ... to 10, Jack, Queen, King and Ace. Ace has the highest value in the same suit. Cards can be compared using their face values. A card with higher face value is bigger than a card with lower face value. If two cards have the same face value, then the suit determines the order. Club is smaller than diamond which is smaller than heart which is smaller than spade. For example: club 2 < diamond 2 < heart 2 < spade 2 if compared.Write an interactive Java program that allows you play cards with a computer. For this project, we are going to focus on one suit of the deck of cards. There are only 13 cards (value: 2, ... to 10, Jack, Queen, King and Ace) in a suit. To play:(a). You first pick a suit at random from the four suits (club, diamond, heart and spade), and display the suit. (b) Then you randomly draw a card from the suit, and let computer draw a card from the same…Bus timetables specify to the second the exact arrival and departure time of each bus on each stop. You need to pay for the full fare of every bus you ride and different bus lines charge different fees , but they are flat fees (independent of distance travelled on the line) A travel plan is a sequence of stop-time pairs where stop is a location of a bus stop and time is when we arrive at that stop. The plan is feasible if for any two consecutive pairs (a, t) and (b, t′) in the plan there exists a bus that departs after t and arrives at b at exactly t′. That is, a travel plan does not allow us to walk between stops. Assuming that no two buses arrive at the same time at the same stop, a feasible plan uniquely identifies the bus lines that we need to take to realize the plan. The cost of the plan is the sum of the fares we need to pay. Your task is to design an efficient algorithm that given a departure time t, an arrival time t′, an origin stop a and a destination stop b, finds the…Computer Science Exercise: shape [★★★] Write a function same_shape : 'a tree -> 'b tree -> bool that determines whether two trees have the same shape, regardless of whether the values they carry at each node are the same. Hint: use a pattern match with three branches, where the expression being matched is a pair of trees. please use Ocaml for the coding
- A deck of cards contains 52 cards with four suits: club, diamond, heart and spade ranging in values from 2, ... to 10, Jack, Queen, King and Ace. Ace has the highest value in the same suit. Cards can be compared using the face value. A card with higher face value is bigger than a card with lower face value. If two cards have the same face value, then the suit determines the order. Club is smaller than diamond which is smaller than heart which is smaller than spade. For example: club 2 < diamond 2 < heart 2 < spade 2 if compared. Write an interactive Java program that allows a user to randomly pick a card from the deck of 52 cards (using a random number between 1 and 4 to represent the four suits: club, diamond, heart and spade and then another random number to represent the face value) to play. Show the suit and face value of the user card. Then the program acts as a card dealer which randomly draws another card and displays the card (again showing the suit and face value of…The Paper Tree store wants a program that calculates and displays the number of single rolls of wallpaper needed to cover a room. The salesclerk will provide the room’s length, width, and ceiling height, in feet. He or she also will provide the number of square feet a single roll will cover. Complete an IPO chart for this problem. Desk-check the algorithm using 10, 12, 8, and 30 as the room’s length, width, ceiling height, and number of square feet a single roll will cover, respectively. Then desk-check it using your own set of data.You are given a Binary Search Tree Program. Uses the Decision Table Test Method to find the Rules, Conditions, and methods. 10 14
- A decision tree with better splits means that: a. all the branches have binary splits. b. the tree has higher accuracy in prediction. c. the branches are of equal depth. d. the tree has more branches.Method: Python Dataset: Census Income Source: https://archive.ics.uci.edu/ml/datasets/Adult Objective The objective of this task is to implement from scratch Decision Tree classification method to predict whether the incomes exceed $50K/yr based on census data. Thus, this is a binary classification problem. The training and test sets are pre-defined in the data set (i.e., in "adult.data" and "adult.test"). Requirements (1) Implement two DT models by choosing any two (2) split criteria from Information Gain, Gain Ratio, Gini Index and Variance. Note that you can use either binary-split or multiple-split. (2) Use (approximately) 2/3 records in "adult.data" for training, and 1/3 records in "adult.data" for post-pruning. (3) Report the accuracy of each model. (4) All DT models must be self-implemented. You CANNOT use any machine learning library in this task. (5) It is recommended that your implementation includes a "tree induction function", a "classification function" and a…The Paper Tree store wants a program that calculates and displays the number of single rolls of wallpaper needed to cover a room.
