Recommender systems come in various types, each with its approach to making recommendations
This type of recommender system suggests items based on the preferences and behaviors of similar users. It assumes that users who liked similar things in the past will continue to do so. For example, if two users have enjoyed similar movies in the past, collaborative filtering might suggest new movies to one user based on the other’s preferences.
Imagine you are using a movie streaming service like Netflix. Collaborative filtering would recommend movies to you based on what users with similar viewing histories and preferences have liked. For example, if you and another user both enjoyed action and adventure movies like “Indiana Jones,” the system might suggest “Jurassic Park” to you because it was well-received by users with similar tastes.
Content-based filtering recommends items to users based on the characteristics of the items and the user’s past interactions. For instance, in a music streaming service, if a user has liked rock songs in the past, the system might suggest more rock songs or artists with similar musical characteristics.
Let’s say you’re using a news app. Content-based filtering would recommend articles based on your past reading habits. If you often read technology articles, the system might suggest a new tech article that matches your interests, even if it’s from a different source.
Hybrid Recommender Systems
These systems combine multiple recommendation techniques to provide more accurate and diverse suggestions. For instance, a hybrid recommender system might use both collaborative filtering and content-based filtering to offer a wider range of recommendations.
Consider an e-commerce website like Amazon. Hybrid systems combine collaborative filtering and content-based filtering.
They might suggest products based on your past purchases (collaborative) and also consider the features of the products themselves (content-based) to offer a diverse set of recommendations.
This approach decomposes user-item interaction data into latent factors and then makes recommendations based on these factors. It’s commonly used in recommendation systems for movies, where it can identify hidden patterns in user preferences.
In the context of music streaming, matrix factorization could break down your music preferences into latent factors. For example, it might discover that you like upbeat songs with catchy melodies, even if you’ve never explicitly stated that. It would then recommend songs with similar latent factors.
Contextual Recommender Systems
These systems consider the context in which recommendations are made, such as the user’s location, time, or device. For instance, a contextual recommender might suggest nearby restaurants based on a user’s current location.
Think about a weather app on your smartphone. A contextual recommender system would provide weather-related recommendations based on your current location. If it’s raining, it might suggest bringing an umbrella or looking up indoor activities.
Association Rule Mining
This technique identifies associations or patterns in user behavior. For example, it might discover that users who buy diapers are also likely to buy baby wipes, leading to recommendations for both products together.
In an online retail store, association rule mining might discover that customers who buy a laptop are likely to purchase a laptop bag as well. So, if you buy a laptop, the system could recommend laptop accessories like bags or mouse pads.
Deep Learning Recommender Systems
Deep learning models, such as neural networks, can be used to learn complex patterns in user data. These systems are capable of handling vast amounts of data and are often used by large-scale platforms like Netflix and Amazon.
