Radius & liblinear parameter C

[SimonTPT]

Hi,

Thanks for your work ! Here are my questions :

• How did you determine "params.max_raio_radius" values? Did you do a cross-validation at some point ?
• How did you find that the optimal cost parameter C for liblinear regression is 1/(size(binaryfeatures, 1) ? Is it optimal for any dataset ?

Thanks

Hi, thank you for the interest. Regarding to your questions:

1. I indeed did some cross-validation to find the ratio_radius for the model;
2. I did remember exactly how to determine the value of C, but it worked well in my experiments.
