    Hello Pratul,
    Thanks for the sessions, very much appreciated. I am a bit confused about my r code for project 5 and would appreciate if you take a look before I submit. I ended up using the PC1 and PC2 for the modeling and I am not sure how to translate that into my predictor variable (GRE and GPA).

    thanks
    Dear Pratul. I couldn't access google drive materials. Please help me to catch up. I started late with R from Sri Sai Ethiopia. As I started late I will finish both the project & the exam a little late. Thank you

    Okay, that really great. In this project, you will be analyzing a data set containing GRE and GPA grades, and trying to predict if a student is accepted or not.

    At first, you will execute some EDA(Exploratory Data Analysis) in the form of basic descriptive statistics and visualisations and then you will dive into implementing a k-means algorithm,

    and a support vector machine (SVM). Thus we can address a question that is on every student’s mind when applying to graduate school!
    For the Practice project to build user based recommendation model for Amazon, yo finding out "What is the average rating for each movie? Define the top 5 movies with the maximum ratings."
    Do we need to calculate the weighted average (average rating based on moving rating and how many users have rated the movie) or simple average?
