- TODO 13 Complete the following Standardization class. Recall that we want to compute the mean and STD for each column! Think about what value we need to set the 'axis' argument equal to in order to achieve this. In the fit() method, compute the mean of the input X using np.mean(). Store the output into the variable self.mean. In the fit() method, compute the STD of the input X using np.std(). Store the output into the variable self.std. In the transform() method, compute and return the standardization for the input X. In other words, convert the standardization general formula into code and return the output. class Standardization(BaseEstimator, TransformerMixin): def __init__(self): pass def fit(self, X, y=None): # TODO 13.1 self.mean = np.mean(X) # TODO 13.2 self.std = np.std(X) # Always return self return self def transform(self, X): # TODO 13.3 return scale = Standardization()scaled_df =…arrow_forwardYou will be using on RV related review comments to train a Sentence completion model. You could use the code below. The code is written in Jupyter notebook python. please follow the following instructions: 1. Build a working sentence completion model. Training data is provided in train.csv. This model should take partial sentences (e.g., "hey how ar," "hello, please") and provide completion for that sentence. Not every input needs to be completed into a correct sentence (e.g., "asdfauaef" does not need to have a sentence completion). For this model's purposes, a sentence is considered completed if an "end of sentence" character (like a full stop, question mark, etc.) occurs within the next five words OR. We predict up to 5 words from the input. 2. BONUS: If you use word vectors or other techniques from what we shared in class using character encoding and have a working model. 3. The test data (test.csv) will be used to evaluate the model. The test file contains partial sentences. Use…arrow_forwardImplement a function or class to solve the Black-Scholed Model Partial Differential Equation. It should be able to price both European and American-style derivatives of arbitrary payoff structure (i.e. the payoff function should be a Callable). Implement full functionality: That is, calculate the price of both European and American options on dividend-paying stocks and be flexible to price other options besides standard calls and puts. Provide documentation: Provide docstrings and example usage for your implementation. It should be easy for someone looking at your code to understand how to call it and what the parameters mean. A short README.md file or example script would be useful.arrow_forward
- Finally, we will do some simple analysis – ranking of words. Write a function word_ranking(corpus, n, sort_index) which takes input parameters corpus (type list), n (type int), and sort_index (type int) and returns a list containing tuples of words and their frequencies in the top n of words. Here, corpus is a list of sentences. n is the number of ranked words to return. The resulting list should then be sorted based on the sort_index; sort_index = 0 should sort the list of tuples in ascending alphabetical order, while sort_index = 1 should sort the list of tuples by the frequencies in descending order. All other numeric values for sort_index should return an empty list (don't need to consider non-integer inputs). For example, we have: corpus = ['hi hi hi hi', 'hello hello say bye', 'bye bye']n = 3sort_index = 1 The function should return: [('hi', 4), ('bye', 3), ('hello', 2)] While sort_index = 0 should return: [('bye', 3), ('hello', 2), ('hi', 4)] You can assume n would…arrow_forwardIn Kotlin, Write a recursive function called myZip, with an expression body. MyZip takes two Lists and returns a List of Pairs in which each value may be any type (I suggest your start by thinking out how to represent this data type). The pairs consist of corresponding elements in the two lists (the first element of the first list and the first element of the second list, etc). The base case should be that either (or both) of the original lists has length 1, so that, if the lists have different length, the zipping stops when the first list runs out of values.arrow_forwardIn Lisparrow_forward
- In matlabarrow_forwardWrite the code in python to define the function has_adjacent_repeats(mystr), which takes a string parameter and returns a boolean result. - If mystr has at least one instance of adjacent characters being equal, return True - Otherwise, return False Hint: You can iterate over the positive indices i for characters in mystr: 1, 2, 3, ...., len(mystr)-1 with a for loop. For each i, if the character at index i matches the character at index i - 1, return True. Otherwise, if no doubled character is found in the entire string, return False. For example: Test Result if not (has_adjacent_repeats("NOODLES") is True): print("error") if not (has_adjacent_repeats("Bananas") is False): print("shwoopsie") if not (has_adjacent_repeats("Hanoverr") is True): print("error")arrow_forwardIn writing a general-purpose sort method in Java, the sort method needs to compareobjects. There are two ways to give the sort method the code to compare objects,implementing the interfaces Comparable and Comparator respectively. Extend Article class toimplement Comparable interface so that the default sorting of the Articles is by its volumearrow_forward
- Write a C++ program with an EuropeanOption class (with fixed strike price K). It should hold information such as option type (call or put), spot price (of the underlying asset), strike price, interest rate, volatility (of the underlying asset) and time to maturity. Constructors don’t accept illegal values. Implement a getPrice() function which gives the price of the option using path independent simulation of the stock prices. Using the following dynamics for the stock price with the constant values: dSt= rStdt + σStdWt S0= 100 K = 105 r = 0.02 σ = 0.05 T = 10. Add more features to the class it should contain four member functions to compute the numerical Greeks (getDelta() for spot price, getRho() for interest rate, getVega() for volatility, and getTheta() for time to maturity) of a given option.arrow_forwardt for several problems you will modify some provided Python code to implement algorithms to solve the same instance of the knapsack problem. After implementing all of the code and solving the problem, you must provide a single table of all results similar to the following: Table 1: Example of results summary (numbers are not realistic) Algorithm Iterations Items Selected Weight Objective Local Search (Best Improvement) 3102 49 97 117 Local Search with Random Restarts (k = 100) Local Search with Random walk (p = 0.25) 9510 121 21 147 2102 87 32 184 etc. Knapsack Problem Definition Given n different items, where each item i has an assigned value (v.) and weight (w), select a combination of the items to maximize the total value without exceeding the weight limitations, W, of the knapsack. IMPORTANT!: When generating random problem instance set you must use the code provided and values: n = 150; max weight of 2500; and, use a seed value (for the random number generator) of 51132023.arrow_forwardWrite a recursive function, numMoves(), that takes a number representing the number of disks in the Hanoi problem, and returns the number of moves involved. I recommend you start writing this function by modifying the hanoi.py program given. Test cases: numMoves(3) should return 7 and numMoves(4) should return 15. Do not use any global variables. hanoi.pyarrow_forward
