Confusion matrix created using made-up data from spam and not-spam email classifiers. Each cell of the table contains counts of how often the situation was observed. Using the counts of each of these occurrences from our contingency table, we can compute precision, recall, or the f1 score (a combination of precision and recall):

The algorithm model evaluation is done using confusion matrix, Receiving Operating Characteristic charts, Cumulative charts, etc. The evaluation also has important metrics as accuracy, sensitivity, precision, etc. After comparing the performances of the algorithm, we save the model to the disk using Pythons pickle model and make use of it for ...

What changes would you expect in the confusion matrix for different values of t? State in particular why it might be useful to include such a “prior boost” factor in a naïve Bayes model For the remainder of the questions, consult the handout What you can do with corpora using just standard Unix command line tools? and the Ken Church ...

In the confusion matrix above, the precision for the class A would be calculated as:Precision. A = tp A /(tp A +e BA +e CA) = 25/(25+3+1) ≈ 0.86The number is reported by RDS as a value between 0 and 1.Recall. Recall is a measure of the ability of a prediction model to select instances of a certain class from a data set. It is commonly also ...
