How Do You Design an Email Spam Filter?

Building a spam filter involves the following process:

The email spam filter will be fed with thousands of emails

Each of these emails already has a label: ‘spam’ or ‘not spam.’
The supervised machine learning algorithm will then determine which type of emails are being marked as spam based on spam words like the lottery, free offer, no money, full refund, etc.
The next time an email is about to hit your inbox, the spam filter will use statistical analysis and algorithms like Decision Trees and SVM to determine how likely the email is spam
If the likelihood is high, it will label it as spam, and the email won’t hit your inbox
Based on the accuracy of each model, we will use the algorithm with the highest accuracy after testing all the models

🥏How Do You Handle Missing or Corrupted Data in a Dataset?
One of the easiest ways to handle missing or corrupted data is to drop those rows or columns or replace them entirely with some other value.

There are two useful methods in Pandas:

IsNull() and dropna() will help to find the columns/rows with missing data and drop them

Fillna() will replace the wrong values with a placeholder value

Why are elliptic curves used in cryptography?

🔸The elliptic curve provides security similar to classical systems (such as RSA), but uses far fewer bits
🔹Implementation of elliptic curves in cryptography requires a smaller chip size, less power consumption, an increase in speed, etc.
