title: Cosine similarity with BigQuery SQL?
body: <p>I have vectors stored in BigQuery (see <a href="https://stackoverflow.com/questions/47028576/how-can-i-compute-tf-idf-with-sql-bigquery">How can I compute TF/IDF with SQL (BigQuery)</a>), and I want to find the most similar between them. How can I compute the cosine similarity with BigQuery standard SQL?</p>
