TL;DR: Event2Vec is a new library for learning simple, additive embeddings of discrete event sequences, making history representation a sum of individual event vectors.
Summary: Event2Vec is a small library designed for learning embeddings of discrete event sequences, such as purchases or logs. Its core innovation is a deliberately simple, additive structure where a history is represented as the running sum of its event vectors. This approach allows for a linear score on a history to decompose exactly into per-event terms.
Why it matters: This offers a computationally efficient and interpretable method for modeling sequential data, beneficial for recommendation systems or user behavior analysis. AI builders should explore its potential for lightweight, explainable sequence modeling in resource-constrained environments.
