Project 9: See how Data Science is used in the field of engineering by taking up this case study of MovieLens Dataset Analysis. The pain point is: finding who purchased a vehicle in the given batch is manual and inaccurate, considering there are thousands of batches that need matching sales, it is very time-consuming and not sustainable. Meanwhile, as a data product, we need to make sure the system can evolve to update the needed parameters and always evaluate the performance along the way.

Using several well documented case studies, the guide then looks at applications and methods including data collection and analysis. So now, we can get the formula for the probability calculation: P(C=c1|V=v1) = P(V=v1|C=c1) / (P(V=v1|C=c1) + P(V=v1|C=c2) + P(V=v1|C=c3)). Data collection for a case study rating. For the specific one asked by our revenue team, the problem is: we cannot assign each sold vehicle to a customer, then we lose the revenue. 1. With this high-level representation, we can build the dependency lineage as Vehicle -> Customer -> Batch.
