Hands-On Unsupervised Learning with Python

Prescriptive analysis

The primary goal of this is to answer the question How can I influence the output of the system? In order to avoid confusion, it's preferable to translate this concept into pure machine learning language, hence the question could be Which input values are necessary to obtain a specific output?

As discussed in the previous section, this phase is often merged together with predictive analysis because the models are generally employed for both tasks. However, there are specific situations where the prediction is limited to a null-input evolution (such as in the temperature example) and more complex models must be analyzed in the prescriptive stage. The main reason resides in the ability to control all the causes that are ...
