This talk is a step-by-step introduction to purchase prediction, also applicable to survival analysis and churn prediction including implementation in PySpark.
When dealing with survival analysis, the model’s success is predicting death correctly. But it can also predict an engine failure, abandonment, or even purchases.
In purchase prediction, survival analysis, or churn prediction, the data is usually labeled or artificially labeled by a set of rules, such as inactivity for 30 days equivalent to churn. But the data structure is different from classical machine learning, and the data handling and modeling are different, too.
This lecture covers the data structures and aggregations for such analysis, focusing on time aggregations using Pyspark and how NLP is involved.
