Users of e-commerce systems generate vast amounts of unstructured, sequential data streams.Each sequence is a varying-length list of directional (timestamped) user-product interactions.There are hidden patterns within those sequences.Users tend to interact with similar products, and interactions change over time.Based on this behavior, we can recommend the sequence of products that the user may be interested in.
