W-Logistic and EqualLabelWeighting

Hi,

the W-Logistic operator throws an exception: "sum of weight of instances less than 1". I'm using the EqualLabelWeighting operator for assigning weights to examples. Shouldn't the summed up weights of all exampes be 1?

Thanks

    Hi,

    yes, in principal the weights created by the [tt]EqualLabelWeighting[/tt] operator should sum to 1 with the default parameter values. Did you check if the error occurs also when you set the [tt]total_weight[/tt] parameter to value greater than 1? Perhaps the weights do not sum exactly to 1 because of rounding errors?

    Regards,

    I tried  [tt]total_weight = 2[/tt] without any problems. I guess you're right with the rounding errors.
