Lab 7 Sample Output

Notes on sample output

Part of the lab is to be sure you can write the BinaryLabels class and the BagOfWordsFeatures class and use them to extract the X and y matrices. Therefore, there will be less guidance on how the sample output below was created. However, the command-line arguments used when running the program will always be shown.

Implementing your own Labeler

Assuming you run your program with the command-line arguments shown below, you should get the following for the y matrix extracted. The output below also assumes that the variable assigned to the instance of the BinaryLabels class is called labeler.

>>> y

[1, 1, 0, 1, 1, 0, 0, 0, 0, 0]

Here is another run with a larger set of articles.

>>> print(y)

[1, 1, 0, 1, 1, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 0, 1, 1, 1, 1, 0, 0, 0, 1, 0, 1, 1, 1, 1, 0, 0, 1, 1, 0, 0, 1, 0, 0, 0, 0, 1, 1, 1, 0, 0, 1, 1, 0, 0, 1, 1, 0, 0, 1, 0, 0, 0, 1, 1, 1, 1, 1, 0, 1, 0, 1, 0, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 1, 0, 0, 0, 0, 1, 1, 1, 1, 0, 0, 0, 1, 1, 1, 0, 1, 1, 1, 1, 1, 0, 0]

>>> print(sum(y))

>>> print(labeler.labels)

{'false': 0, 'true': 1}

Implementing your own Feature Extractor

It is harder to show the lil_matrix completely unless the vocabulary size is drastically limited and the training size is drastically limited. In addition, the lil_matrix doesn’t have a nice way of converting itself to a string for easy viewing, so the example below shows how to convert it to a dense matrix (for debugging very small cases only) so you can compare your output. The code below assumes that the variable assigned to the instance of the BagOfWordsFeatures class is called bow_features.

>>> print(repr(X))

<10x20 sparse matrix of type '<class 'numpy.uint8'>'

with 49 stored elements in List of Lists format>

>>> print(X.toarray())

Classifying data

Here are some sample runs on small sets using the MultinomialNB classifier with no optional arguments. The first set of sample runs uses 5-fold cross-validation and assumes that you set the return value of cross_val_predict to the variable class_probs, and your final prediction for each instance to the variable y_pred.
