Making every user experience unique by adding a touch of personalization is no longer a luxury—it’s an expectation. From shopping online to social media feeds, users crave to see tailored experiences to his or her needs and wants. As experts summarize, “Personalization is no longer just about user experience; it’s about creating meaningful connections in a digital landscape.” Businesses need to transform to foster a deeper relationship with customers, and Machine Learning (ML) is a key player in this. 

With digital advancement, machine learning is vital in personalizing user experiences and reaching new heights. It enables businesses to customize their products and services to meet customers’ unique needs and preferences. 

Machine learning-based personalization offers a more accurate and scalable approach to achieving one-to-one user experiences by using algorithms, usually in terms of personalized recommendations of products or content. So, how does machine learning personalize user experiences? And what is the correlation between AI and machine learning personalization? Let’s find out!

Role of Machine Learning Algorithms for Personalization

Personalization can be described as a way to suggest the right things, products, content, or items to the right user. This helps encourage the user to spend more time interacting with the platform. With the help of machine learning algorithms and extensive user data, models can precisely predict customer intent and provide quality one-to-one recommendations.

A machine learning model comprises statistical and probabilistic models that work towards a defined end. It is basically finding a mapping between a set of input x and output y. The algorithms analyze voluminous datasets to identify trends. This helps in extrapolating what’s most likely going to happen or what type of experience will lead to a particular result.

Different machine learning algorithms are used for personalization, including Regression analysis, Association, Clustering, Markov Chains, and Neural Networks.

Recommendation System: Application of ML-Based Personalization

Recommender systems, or recommendation engines, are information filtering systems that provide individual or personalized recommendations in real life. They are based on ML models and algorithms to provide relevant suggestions to specific users by understanding their past behavior and predicting their current needs.

Based on the type of recommendation required, there are three approaches to building a recommender system:

• Content-based Filtering: It generates the prediction by analyzing the item attributes and searching the similarities between them. 
• Collaborative Filtering: It generates prediction by analyzing the user behavior and matching the users with the same preference. 
• Hybrid Filtering: It combines two or more models to provide recommendations.

Let’s see how these approaches work:

1. Content-based Filtering (CBF)

The CBF model works by using specific attributes of items to find similarities between them. Depending on the description information, which includes the characteristics of items or users, the model creates data profiles. These profiles are used to recommend similar items that users might like to watch or buy.

For example, let’s discuss movie recommendations. Common attributes include genre, film director, and cast. For instance, if a user has watched Inception, Interstellar, and Oppenheimer, then the CBF model will recommend the following recommendations:

• More movies by Christopher Nolan 
• More Sci-Fi and Thriller movies 
• More historical-based drama movies 
• More movies with complex narratives 

As the user goes on making choices, the CBF model tailors the recommendations as it gains a wide collection of attributes.

2. Collaborative Filtering (CF)

Collaborative filtering is the most commonly implemented method because it provides relevant recommendations based on interactions between different users with the same target items. This approach predicts how a person (a model has never interacted with before) would react to the items.

Hence, recommender systems based on this approach gather past user behavior information and then mine the items to display to other active users with the same taste. Let’s understand this with another movie example. There is a user, A, who has watched The Dark Knight (directed by Christopher Nolan), The Matrix (directed by the Wachowskis), and Fight Club (directed by David Fincher).

There is another user, B, who likes Pulp Fiction (directed by Quentin Tarantino) in addition to The Matrix and Fight Club. There is a good chance that user A might like Pulp Fiction and B might like The Dark Knight because of their shared interest in gritty, action-packed films with complex narratives.

In real life, a CF-based recommender system examines the interaction of millions of users.

3. Hybrid Filtering (HF)

Hybrid Filtering combines multiple recommendation techniques to achieve the highest recommendation accuracy while reducing the cons. All modern recommendation systems implement hybrid filtering. For example: a hybrid recommendation engine can be built by combining collaborative and content-based filtering approaches.

The engine collects and analyzes the behavior of different users and makes a cluster of users with the same taste. It also uses the attributes extracted from past behavior. It combines everything to provide the best recommendation.

Machine Learning in Customer Experiences

Employing machine learning, businesses deliver personalized customer experiences by processing and analyzing data to know what are trendy searches and patterns. To analyze customer patterns, machine learning algorithms use clustering, classification, and predictive modeling, enabling businesses to get better insights into their behavior, needs, and preferences. Now, you understand what machine learning algorithms are and their relevance in personalization. Let’s comprehend what is machine learning in customer experiences with real-world examples:

Netflix, Amazon, and Spotify all use machine learning to make their services better for users. 

• Netflix

With 277.65 million paid subscribers worldwide, Netflix is renowned for its intelligent recommendation systems. It uses machine learning algorithms to understand what you watch and like, then offers a “Recommended for You” section that suggests movies and TV shows you might enjoy based on your taste. This keeps users engaged and watching longer, which ultimately drives more subscriptions and income. 

• Amazon

Amazon deploys machine learning techniques like collaborative filtering and predictive analytics to learn what you buy and browse and recommend products you might want. Columns like “Customers Who Bought This Item Also Bought” and “Frequently Bought Together” use machine learning algorithms to offer relevant product recommendations, boosting cross-selling and customer satisfaction.
