As businesses today must rely on personalizing user experiences, recommenders reduce the legwork for retail, entertainment, and e-commerce manufacturers, and in Alteryx, the data prep and analytics capabilities make building recommenders a streamlining exercise. We have for you the step-by-step guide on doing that using Alteryx.
Step 1: Understand your use case
A detailed understanding of your use case should be done before technical implementation begins. Do you build a system that recommends products, movies, or services? Outline your target audience – that is a count of users if possible – and the kind of data available, as well as the end-goal of your recommendation system.
Step 2: Gather and prepare data
Your data quality will be crucial in building a successful recommender system. Using Alteryx, you will be able to blend and clean your dataset efficiently.
- Data integration: The Input Data tool in Alteryx allows a connection to different types of data sources should they be databases, APIs, or spreadsheets.
- Data cleaning: Tools like Data Cleansing, Filter, and Select help remove missing values, duplicates, and inconsistencies.
- Feature engineering: Use Alteryx’s transformation tools to extract meaningful features like user demographics, product attributes, and past interactions.
Step 3: Select the recommendation method
In general, recommender systems feature one of the three methods outlined below:
- Collaborative Filtering: Leverages existing user behavior, like purchase history or ratings, to establish recommendations.
- Content-Based Filtering: Uses item attributes to recommend similar items to the user.
- Hybrid Method: A combination of collaborative and content-based methods that produce better accuracy.
Using Alteryx, you can take advantage of such methods through a workflow approach that combines data processing with analytics.
Step 4: Developing the recommender model
Collaborative filtering: You can use Association Analysis or predictive group tools in Alteryx to extract user behavioral patterns.
Content-based filtering: Analyze various product characteristics in Alteryx’s text analytics and similarity in functions, which will then compute recommendations.
Machine learning: Create more sophisticated recommendations in Alteryx using ML tools such as Decision Trees and Logistic Regression.
Step 5: Testing and evaluating the model
Use historical data to evaluate the performance of your recommender system. The Model Evaluation offers Alteryx tools such as the Confusion Matrix or Lift Charts that may help in determining accuracy and effectiveness.
Step 6: Deploy and automate
With the help of Alteryx workflow automation capabilities, put the machine learning models to production. This will make model’s predictions available to end users. Have fixed routine for workflows so that it will refresh the recommendations based on the new data. This will keep the system up to date over a period of time.
Step 7: Monitor and improve
Periodically measure the recommender system and compare it with various metrics like CTR, conversion rates and customer satisfaction and build the product to satisfy the customer needs.
The Alteryx framework helps from data preparation to the output in building a recommender system. The above steps will help create an effective and buildable recommender system and it delivers value added experience to users.
Alteryx makes it easy for employees with no data management experience or even an analyst to get the right results by converting raw data to actionable recommendations.
