Which algorithm is used for spam detection?
Some of the most popular spam email classification algorithms are Multilayer Perceptron Neural Networks (MLPNNs) and Radial Base Function Neural Networks (RBFNN). Researchers used MLPNN as a classifier for spam filtering but not many of them used RBFNN for classification.
What are some common algorithms used in unsupervised learning?
Below is the list of some popular unsupervised learning algorithms:
- K-means clustering.
- KNN (k-nearest neighbors)
- Hierarchal clustering.
- Anomaly detection.
- Neural Networks.
- Principle Component Analysis.
- Independent Component Analysis.
- Apriori algorithm.
Which algorithm is used in unsupervised machine learning?
k-means Clustering – Data Mining k-means clustering is the central algorithm in unsupervised machine learning operations. It is the algorithm that defines the features present in the dataset and groups certain bits with common elements into clusters.
How do you detect spam?
How to Identify Spam
- Check for typos or strange phrasing. This can be indicative of a spam email.
- Check for strange or unfamiliar links.
- Check for context.
- Be wary of emails asking for personal information.
- Check to make sure the From and Reply To address match.
- Does it sound too good to be true?
How do spam algorithms work?
When you mark a message as spam, it goes into a hopper with millions of messages that others have flagged. Algorithms churn through these messages to find similar characteristics, such as word proximity or misspellings, that show up frequently in spam.
What are machine learning algorithms used for?
At its most basic, machine learning uses programmed algorithms that receive and analyse input data to predict output values within an acceptable range. As new data is fed to these algorithms, they learn and optimise their operations to improve performance, developing ‘intelligence’ over time.

What is spam in information security?
Spam refers to unsolicited bulk messages being sent through email, instant messaging or other digital communication tools. Beyond being a simple nuisance, spam can also be used to collect sensitive information from users and has also been used to spread viruses and other malware.
