I recorded a brief introduction to the OTTO RecSys competition on Kaggle!

We start with the baseline and build on top of it by progressively adding more advanced ideas:

• co-visitation matrix
• manual reranking
• reranking using a model
• word2vec & matrix factorization for candidate generation and scoring

Meant as a brief introduction both to the OTTO competition and a couple of foundational ideas in RecSys.

Hope you find it a good watch! 🙂
