Multivariate regresstion with variable size input

I want to fit a machine/deep learning model to fit below table data format F1-F5 are features and Y gets captured is a random time interval.

f1    f2    f3    f4    f5    y
11    12    13    14    15    
.                             
.                             
.                             
n1    n2    n3    n4    n5    2.3
n+11  n+12  n+13  n+14  n+15
.
.
n+x1  n+x2  n+x3  n+x4  n+x5  3.5

I am confused to go whether to go with CNN kind of approach, multiplying 1*5 sized kernel through every row from 11-n1 and try to learn by matching sum with Y. Kindly suggest me how to tackle such data.
