Project 1

## Finding Similar Movie Critics - Recommendation System

We are having a small data set of movie critics with their reviews/ratings for different movies. We will be building an algorithm using the basic concepts of python programming. It will find similar to a given critic's name based on their movie reviews.

• Variable declaration, assigning values to the variables and using print function.
• Conditional and loop statements - Use of if and for
• Use of different data types and handling the data
• Functions and use of user defined functions
• Euclidean Distance Algorithm

• What will be the output of the following code- DeZyre_DataScience_List = [1, 20, 3, 40, 5, 60]; DeZyre_DataScience_List.append ([“45”,”55”]);?

On executing the above python list append function both the values will be appended at the end of the list as a single element only. When using append for python lists, regardless of whether you have a single element or multiple elements- it will be added as a single element. To confirm this you can just try to print the length of the DeZyre_DataScience_List after executing the python list append function as shown above.

Print (“Number of Elements in the List is: len (DeZyre_DataScience_List));

Output:

Number of Elements in the List is: 7

• How do Random Forest Works?

Random forests are a combination of tree predictors such that each tree depends on the values of a random vector sampled independently and with the same distribution or all trees in the forest. The generalization error for forests converges as to a limit as the number of trees in the forest becomes large. The generalization error of a forest of tree classifiers depends on the strength of the individual trees in the forest and the correlation between them.
