What does a unexpected "Constant" row mean in output file "scores.txt"? #29

Closed blueblued closed 7 years ago

Hi, Arielf, I got something like this(factors in chinese):

FeatureName HashVal MinVal MaxVal Weight RelScore Constant 142054 1.00 1.00 -0.02 -100.00 花生 247270 1.00 10.00 -0.01 -73.55 素三鲜白菜 176662 1.00 20.00 -0.00 -23.43 韭菜鸡蛋饼 86006 1.00 20.00 -0.00 -22.81 ......

I don't have any factor "Constant", is it a bug?

blueblued commented 7 years ago

I try to replace the chinese factor name to numeric id, and get the same result (The "Constant" row).

Hers is the raw data (with factors' name in numeric format), may you check it and give me any suggestion? Thanks!

Not a bug. Constant is the name of your bias term (aka the intercept of the linear regression) Also there's no need to replace names by numeric IDs and back.
