I need some serious help with this decision tree algorithm for my machine learning class. Be sure to read the code requirements below, because i need to write some parts from scratch. Any and all help would be VERY appreciated. Thank you!

Decision Tree Lab In [ ]: from sklearn.base import BaseEstimator, classifierMixin from sklearn.tree import DecisionTreeclassifier import numpy as np import matplotlib.pyplot as plt 1. (40%) Correctly implement the ID3 decision tree algorithm, including the ability to handle unknown attributes (You do not need to handle real valued attributes). Code Requirements/Notes: Use standard information gain as your basic attribute evaluation metric. (Note that normal ID3 would usually augment information gain with gain ratio or some other mechanism to penalize statistically insignificant attribute splits. Otherwise, even with approaches like pruning below, the SSE type of overfit could still hurt us.) You are welcome to create other classes and/or functions in addition to the ones provided below. (e.g. If you build out a tree structure, you might create a node class). It is a good idea to use a simple data set (like the lenses data or the pizza homework), which you can check by hand, to test your algorithm to make sure that it is working correctly.
