Machine learning based recommendation system construction is a famous concept that provides an importance of recommendation framework in various applications such as music streaming, online purchasing and movie suggestions. Below, we describe the procedural flow to develop a recommendation framework:

  1. Problem Description:

Describe the type of recommendation framework that we intend to develop:

  • Collaborative Filtering: Based on customer-product communications, our work suggests products.
  • Content-Based Filtering: In this, by comparing content characteristics, we suggest products.
  • Integrated Model: We integrate collaborative and content-based filtering approaches.
  • Learning-to-Rank: Our project ranks the provided group of products for customers.
  1. Data Collection:
  • Initially, we begin with the datasets such as MovieLens dataset and also acquire datasets having customer-product communications (buying history, reviews, clicks, etc.).
  • Gather product metadata (for instance: item description, film categories), if we are dealing with a content-based approach.
  1. Preprocessing of Data:
  • In the preprocessing steps, we manage the missing values.
  • Our work encodes categorical information.
  • If required, we normalize or standardize number-based data.
  1. Exploratory Data Analysis (EDA):
  • We interpret the distribution of reviews or customer communications.
  • In customer activities, we detect patterns.
  • For content-based filtering, our project examines the distribution of product metadata.
  1. Feature Engineering:
  • Our work intends to transform product metadata into feature vectors (for example: TF-IDF for text-related data) in a content-based filtering approach.
  • We directly utilize customer and product IDs with techniques such as matrix factorization in collaborative filtering.
  1. Model Chosen:
  • Collaborative Filtering: In this approach, we employ deep learning frameworks like neural collaborative filtering and matrix factorization techniques (for instance: Singular Value Decomposition).
  • Content-based Filtering: Our work utilizes decision trees, Cosine similarity and Neural networks assist us to work on product features.
  • Integrated Model: We integrate the frameworks from the above two approaches.
  1. Training the Model:
  • Our project divides the data into training sets and validation or testing sets.
  • By using training dataset, we train our chosen framework
  1. Evaluation:
  • Root Mean Square Error (RMSE): We consider this for frameworks which forecast ratings.
  • Precision@k, Recall@k: For models which suggest a list of products, we utilize these metrics.
  • Mean Average Precision, NDCG: Our project considers this specifically for ranking tasks.
  1. Optimization:
  • In this process, we adjust the hyperparameters.
  • Our work considers the utilization of integrated techniques.
  1. Deployment:
  • With a mobile or web application, we combine our recommendation framework.
  • Our research offers customers with suggestions in actual-time or batch mode.
  1. Feedback Loop:
  • We capture the customer reviews on suggestions.
  • Our goal is to frequently reconstruct and retrain the framework through the utilization of these reviews.

Tools & Libraries:

  • Data Handling & EDA: For this purpose, we use Seaborn, NumPy, pandas or Matplotlib.
  • Collaborative Filtering: In this approach, our project considers TensorFlow, Surprise library or Keras.
  • Content-Based Filtering: We utilize Scikit-learn for cosine similarity and TF-IDF.


  • Cold Start Problem: It is difficult for us to manage the new customers or products without any communications. Therefore, at first, utilize integrated models or content-based suggestions.
  • Diversity: Make sure our framework doesn’t suggest similar kinds of products frequently, because it leads to a filter bubble.
  • Scalability: For huge-scale suggestion frameworks, we need distributed computing approaches such as Spark (with the use of ALS technique for collaborative filtering).

We conclude that the creation of a recommendation framework is a complicated one but it is a very beneficial attempt, providing its actual-world applications and effectively improving customer experience in several applications. Often we need to retrain our framework, integrate customer reviews and adapt to modify patterns and suggestions.
