Regarding data sparsity in context aware datasets

[madhuriramesh]

Hello,

I am interested in the "In-car music" publicly available dataset and tried using it to train the CARSKit algorithm.
The dataset is very sparse and I need a solution for this so that the algorithm can give accurate results.
I already came across the option of deleting corresponding columns/rows with sparse values but thats not possible since mostly all rows and columns have lot of sparse values.
Please provide a solution to the problem .
Thanks in advance for your help.

Regards,
Madhuri
