This post discusses the limitations of using cosine similarity for compatibility matching, specifically in the context of a dating app. The author found that high cosine similarity scores didn't always translate to actual compatibility due to the inability of embeddings to capture dealbreaker preferences. They improved results by incorporating structured features and hard filters.
ow can you learn about the underlying structure of documents in a way that is informative and intuitive? This basic motivating question led me on a journey to visualize and cluster documents in a two-dimensional space. What you see above is an output of an analytical pipeline that begin by gathering synopses on the top 100 films of all time and ended by analyzing the latent topics within each document. In between I ran significant manipulations on these synopses (tokenization, stemming), transformed them into a vector space model (tf-idf), and clustered them into groups (k-means). You can learn all about how I did this with my detailed guide to Document Clustering with Python. But first, what did I learn?
