Overview
Context
This Building Recommendation Engines with PySpark course offered by Data Camp will show you how to build recommendation engines using Alternating Least Squares in PySpark.
Using the popular MovieLens dataset and the Million Songs dataset, this course will take you step by step through the intuition of the Alternating Least Squares algorithm as well as the code to train, test and implement ALS models on various types of customer data.What you will do during this course:
- You will learn a very powerful way to uncover hidden features (latent features) that you may not even know exist in customer datasets.
- You will review basic concepts of matrix multiplication and matrix factorization, and dive into how the Alternating Least Squares algorithm works and what arguments and hyperparameters it uses to return the best recommendations possible. You will also learn important techniques for properly preparing your data for ALS in Spark.
- You will be introduced to the MovieLens dataset. You will walk through how to assess it's use for ALS, build out a full cross-validated ALS model on it, and learn how to evaluate it's performance. This will be the foundation for all subsequent ALS models you build using Pyspark.
