Description:

Millions of visitors visit business websites every day and each one of them takes different set of steps in order to seek the right information/product. Yet most of them leave disappointed or dejected for some reason and very few get to the right page within the website. In this kind of situation, it becomes difficult to find out if the visitor actually got the information that he was looking for? Also, the individual journeys of these visitors can’t be compared to each other since every visitor has done different set of activities. So, how can we know more about these journeys and compare these visitors to each other? Sequence Embedding is a powerful way that offers us the flexibility to not only compare any two distinct visitors entire journey in terms of similarity but also to predict the probability of visitor’s conversion. Sequence embeddings essentially helps us to move away from using traditional features to make predictions and considers not only the order of the activities of a user but also the average time spent on each of the unique pages to translate into more robust features and used in Supervised Machine Learning across multiple use cases (next possible action prediction, converted vs non-converted, product classification) .Using traditional Machine learning models on the advanced features like sequence embeddings, we can achieve tremendous results in terms of prediction accuracy but the real benefit lies in visualizing all these user journeys and observing how distinct are these paths from the ideal ones.

This session will unfold the process creating sequence embeddings for each user’s journey in python and use them to build machine learning classification model to predict visitor conversion along with comparing all the user journeys in terms of similarity score.
