**Use Cases**

**Recommendation engines** : Data filtering and they use collaborate or content based filtering.The retailers tend to use recommendation engines as one of the main leverages on the customers opinion.

**Market basket analysis**: Its basically Traditional tool of data analysis. Data mining analysis will be applicable here. This process mainly depends on the organization of a considerable amount of data collected via customers transactions.

**Warranty analytics : **Warranty analytics comes in picture of retail as a tool of warranty claims monitoring, detection of fraudulent activity, reducing costs and increasing quality. …

**A scenario :** Where student trying to learn formulas math problem. He is byhearting math prob. In exam for questions he is unable to answers..so there is an issue..!!!

Different Ways to Handle typical situation

1. We stop student memorizing numbers.

2. Check him if he memorizing numbers every step.

3. Give similar practice problems

4. Give only formulas to generalize

5. Make him practice only few aspects.

6. Adding ,previous problems so to check he is memorizing or not.

A **decision tree** where the target variable takes a continuous value, usually numbers, are **called** Regression **Trees**. The two types are commonly referred to together at CART (Classification and Regression **Tree**).

The **decision** to split at each node is made according to the metric **called** purity . A decision tree has many analogies in real life, and turns out that it has influenced a wide area of **machine learning**, covering both **classification and regression**. In decision analysis, a decision tree can be used to visually and explicitly represent decisions and decision making.
