Introduction Machine learning is an area of computer science whose aim is to create programs which improve their performance with experience. There are many applications for this, including: face recognition, recommendation systems, defect detection, robot navigation, and game playing. For this assignment, you will implement a simple machine learning algorithm called Nearest Neighbor which learns by remembering training examples. It then classifies test examples by choosing the class of the "closest" training example. The notion of "closeness" differs depending on applications. You will need to use the Nearest Neighbor algorithm to learn and classify types of Iris plants based on their sepal and petal length and width. There are three Iris types you will need to classify: Iris Setosa Iris Versicolour Iris Virginica The learning will be done by remembering training examples stored in a comma-separated file. The training examples include different measurements which collectively are called features or attributes, and a class label for different instances. These are: 1. sepal length in cm sepal width in cm 3. petal length in cm 4. petal width in cm Paco 5. class: - Iris Setosa -- Iris Versicolour Iris Virginica To see how well the program "learned", you will then load a file containing testing examples, which will include the same type of information, but for different instances. For each test instance, you will apply the Nearest Neighbor algorithm to classify the instance. This algorithm works by choosing a class label of the "closest" training example, where "closest" means shortest distance. The distance is computed using the following formula: dist(x,y) = -J(sl s1,)* + (swx - sw.)? + (plx ply)? + (pwx pw,)? where x,y are two instances (i.e. a training or a testing example), slz,sly are their sepal lengths, sw,,sw, are their sepal widths, plx.ply are their petal lengths, and pwx.pw, are their petal widths. After you finish classifying each testing instance, you will then need to compare it to the "true" label that is specified for each example and compute the accuracy. Accuracy is measured as the number of correctly classified instances divided by the number of total testing instances. Requirements You are to create a program in Python 3 that performs the following: 1. Loads and parses the training and testing dataset files into separate Numpy ndarrays. Given what you know, the easiest way to do this is to create four separate arrays: 2D array of floats for storing oring training example attribute values 2D array of floats for storing testing example attribute values 1D array of strings for storing training example class labels 10 array of strings for storing testing example class labels You can assume there are exactly 4 attribute values in the training and testing examples. 2. Classifies each testing example. You also need to output the true and predicted class label to the screen and save it into a new 10 array of strings. This is done by first computing the distance value for each pair of training and testing examples (their attribute values). Then, for each test example, find the training example with the closest distance. You can do all that easily with NumPy's vectorized functions - you shouldn't use loops for this. 3. Computes the accuracy. Go through the array of class labels for testing examples and compare the label stored in the array created in step (2). Count how many matches you get. Output the number of matches, divided by the number of testing examples as a percentage. Additional Requirements 1. The name of your source code file should be NearestNeighbor.py. All your code should be within a single file. 2. You cannot import any package except for Numpy. 3. Your code should follow good coding practices, including good use of whitespace and use of both inline and block comments. 4. You need to use meaningful identifier names that conform to standard naming conventions. 5. At the top of each file, you need to put in a block comment with the following information: your name, date, course name, semester, and assignment name. 6. The output of your program should exactly match the sample program output given at the end.
