-> Question: How do you get assigned to SimClusters?
Answer: The assignment to SimClusters occurs through a Metropolis-Hastings sampling-based community detection algorithm that is run on the Producer-Producer similarity graph. This graph is created by computing the cosine similarity scores between the users who follow each producer. The algorithm identifies communities or clusters of Producers with similar followers, and takes a parameter k for specifying the number of communities to be detected.
After the community detection, different users and content are represented as sparse, interpretable vectors within these identified communities (SimClusters). The resulting SimClusters embeddings can be used for various recommendation tasks.
-> Question: What is needed to migrate from one SimClusters to another SimClusters?
Answer: To migrate from one SimClusters representation to another, you can follow these general steps:
Prepare the new representation: Create the new SimClusters representation using any necessary updates or changes in the clustering algorithm, similarity measures, or other model parameters. Ensure that this new representation is properly stored and indexed as needed.
Update the relevant code and configurations: Modify the relevant code and configuration files to reference the new SimClusters representation. This may involve updating paths or dataset names to point to the new representation, as well as changing code to use the new clustering method or similarity functions if applicable.
Test the new representation: Before deploying the changes to production, thoroughly test the new SimClusters representation to ensure its effectiveness and stability. This may involve running offline jobs like candidate generation and label candidates, validating the output, as well as testing the new representation in the evaluation environment using evaluation tools like TweetSimilarityEvaluationAdhocApp.
