Hashing Project in Python to Extract Features of Names
You are given the following three functions. They take plain text names and covert then into features vefctors so that you can work with them in a classification system.
Let's check your understanding of Python function. Add notes to each line describing what is happening in these functions.
FUNCTION ONE:
def hashfeatures(baby, B, FIX):
"""
Input:
baby : a string representing the baby's name to be hashed
B: the number of dimensions to be in the feature vector
FIX: the number of chunks to extract and hash from each string
Output:
v: a feature vector representing the input string
"""
v = np.zeros(B)
for m in range(FIX):
featurestring = "prefix" + baby[:m]
v[hash(featurestring) % B] = 1
featurestring = "suffix" + baby[-1*m:]
v[hash(featurestring) % B] = 1
return v
FUNCTION TWO:
def name2features(filename, B=128, FIX=3, LoadFile=True):

Output:

- C++ Complete the program that will allow the user to enter data on 10 Halloween costumes. The program will create Costume objects and then store the Costume objects in a Hash Table. The Costume ID will be the key and a pointer to the Costume object will be the value. You are given Lab7.cpp, HashEntry.h, and Costume.h and you should not have to make any changes to these files at all. You will need to write HashTable.h, which implements the HashTable class. This should NOT be a template class. Your HashTable class should resolve collisions by linear probing and should use the HashEntry class for the linkedlist nodes. Because we’re using probing, there is no removal function. This is okay for this application, since we want to keep a record of costumes that are no longer being kept in stock. ---GIVEN--- Lab.cpp #include <iostream> #include "HashTable.h" #include "Costume.h" using namespace std; int main() { int size; int key; Costume *newCostume; string name; float price;…arrow_forwardshared ptr sPtr { make_unique () }; Should we expect an error?

Once you specify the type stored in a generic collection, any reference you retrieve from the collection will have that type. Instructions Write a program that inserts 25 random integers from 0 to 100 in order into Java’s LinkedList object (you must use Java’s LinkedList class to get any credit for this assignment). The program must: sort the elements, then calculate the sum of the elements, and calculate the floating-point average of the elements. For this assignments make sure that your screen shot(s) show your program running and that your runtime display shows your random list, sorted list, sum of the elements, and average of the elements. You only get credit for what you demonstrate. Below is a sample screen shot. Your output doesn’t have to look…arrow_forward
