    Thanks,
    Karthik

    Hi Prashanth,

    I'm working on the Movielens project. In the ML section I did not understand the use case. It just says to prepare histogram for movie id, age and occupation. Could you help me on this.

    Hi Prashant,

    Please see attached the Iris and Cars assignment and kindly point out any errors if any.

    On cars, I initially used 2 variables as given but the model score was too poor. I then added another variable and re-ran the model to a better result.

    Please see attached.
