What is a Recommendation system?

There are a lot of applications where websites collect data from their users and use that data to predict the likes and dislikes of their users. This allows them to recommend the content that they like. Recommender systems are a way of suggesting similar items and ideas to a user’s specific way of thinking.

There are basically two types of recommender Systems:

  • Collaborative Filtering: Collaborative Filtering recommends items based on similarity measures between users and/or items. The basic assumption behind the algorithm is that users with similar interests have common preferences.
  • Content-Based Recommendation: It is supervised machine learning used to induce a classifier to discriminate between interesting and uninteresting items for the user.

In this article, we will mainly focus on the Collaborative Filtering method.

Collaborative Filtering in Machine Learning

If this time you are watching a horror video on youtube then next time you will automatically see some more horror videos in your feed have you ever thought about how this thing works?  Like how an application was able to get to know about your choices and likes. This is exactly what is popularly known as Recommendation Systems.

What is Collaborative Filtering?

In Collaborative Filtering, we tend to find similar users and recommend what similar users like. In this type of recommendation system, we don’t use the features of the item to recommend it, rather we classify the users into clusters of similar types and recommend each user according to the preference of its cluster....

Advantages of Collaborative Filtering-Based Recommender Systems

As we know there are two types of recommender systems the content-based recommender systems have limited use cases and have higher time complexity. Also, this algorithm is based on some limited content but that is not the case in Collaborative Filtering based algorithms. One of the main advantages that these recommender systems have is that they are highly efficient in providing personalized content but also able t adapt to changing user preferences....
