💻 Practical Example

The following example shows how an AI model can classify emails as spam or not spam using a machine learning algorithm.

Simple AI Classification Example

from sklearn.naive_bayes import MultinomialNB
from sklearn.feature_extraction.text import CountVectorizer

emails = [
    "Congratulations! You won a prize",
    "Meeting scheduled for tomorrow"
]

labels = [1, 0]

vectorizer = CountVectorizer()
X = vectorizer.fit_transform(emails)

model = MultinomialNB()
model.fit(X, labels)

sample = vectorizer.transform(["Claim your free reward"])
prediction = model.predict(sample)

print(prediction)

📐 A Simple AI Performance Measure

One common way to evaluate a classification model is by calculating its accuracy.

A cc u r a cy = \frac{N u mb er o f C or r ec t P r e d i c t i o n s}{T o t a l N u mb er o f P r e d i c t i o n s}
